what is 3-4y=19 for math 8

Functions can be reflected on the x-axis, the y-axis, or both axes. For example, function reflection y= f(x) can be written as y= -f(x) or y= f(-x) even y= -f(-x). There are four types of function or graph transformations: reflection, rotation, translation, and dilation. In mathematics, especially geometry, mirror or mirroring means flipping, so basically, the mirroring of a function is the mirror image of a given function or graph. Hence the reflection function is commonly known as the reflection function.

The reflection of the given function should be similar in size and shape to the original function.

In an equilateral triangle, all the four points (circumcenter, incenter, orthocenter, and centroid) coincide.

The incenter is important for angle bisectors; the orthocenter is important for perpendicular bisectors; the circumcenter is important for altitudes; and the centroid is important for medians.

All four points (circumcenter, incenter, orthocenter, and centroid) of an equilateral triangle coincide.

The circumcenter is the point at which the perpendicular bisectors of all three sides of a triangle intersect. The circumcenter of an obtuse-angled triangle is located outside the triangle.

All four points of convergence can be concurrent. Only an equilateral triangle has the same centroid, circumcenter, incenter, and orthocenter at all times.

The 'orthocenter' is the point at which the altitudes of a triangle coincide. The orthocenter of a triangle is the point at which the triangle's three altitudes intersect.

Answer:

Frictional force (F(frict)) = 17.1 N

Normal force (F(norm)) = 78.0 N

Gravitational force (F(grav)) = 63.7 N

Acceleration (a) = 1.2 ms⁻²

Step-by-step explanation:

Newton's second law:

[tex]\boxed{F_{net}=ma}[/tex]

where:

Use trigonometry to resolve the 28.5 N force into its horizontal and vertical components since it is acting on the particle at 30°:

[tex]\implies F_x=28.5 \cos 30^{\circ}[/tex]

[tex]\implies F_y=28.5 \sin 30^{\circ}[/tex]

Due to the particle's mass, m, and the acceleration due to gravity, g:

[tex]\boxed{W=mg}[/tex]

Given:

[tex]\begin{aligned}W & = mg\\\implies W & = 6.5 \times 9.8\\W & = 63.7\;\sf N\end{aligned}[/tex]

The particle is moving parallel to the plane (the horizontal), so acceleration perpendicular to the plane is zero.

Resolving forces vertically (taking ↑ as positive):

[tex]\begin{aligned}F & = ma\\\implies R-W-28.5 \sin 30^{\circ}&=6.5 \times 0\\R-W-28.5 \sin 30^{\circ}&=0\\R & = W+28.5 \sin 30^{\circ}\\R & = 6.5(9.8)+28.5(0.5)\\R & = 63.7+14.25\\R & = 77.95\\R & = 78.0 \;\; \sf N\; (1\:d.p.)\end{aligned}[/tex]

When a moving object is acted on by a frictional force, fiction is limiting, and the frictional force F is at its maximum value:

[tex]\boxed{F = \mu R}[/tex]

(Where μ is the coefficient of friction and R is the normal reaction).

[tex]\begin{aligned}F & = \mu R\\\implies F & = 0.22 \times 77.95\\F & = 17.149\\F & = 17.1 \;\; \sf N\;(2\:d.p.)\end{aligned}[/tex]

Friction always acts in the opposite direction to motion (or potential motion).

Resolving forces horizontally (taking → as positive):

[tex]\begin{aligned}F & = ma\\\implies 28.5 \cos 30^{\circ}-F & = 6.5a\\28.5 \left(\dfrac{\sqrt{3}}{2}\right)-17.149 & = 6.5a\\\dfrac{57\sqrt{3}}{4}-17.149 & = 6.5a\\7.532724008 & = 6.5a\\a & = 1.158880617\\a & = 1.2\; \sf ms^{-2}\;\;(1\:d.p.)\end{aligned}[/tex]

The answer type is interval and the interval is (-∞,5).

The value of x is the domain for which the function is defined. Function in this case can use value from (-∞,5).

Graphs can be used to specify the domain and set of functions. The domain of a graph is made up of all the input values displayed on the x-axis since the term "domain" refers to the set of potential input values. The range is the collection of potential output values, as displayed on the y-axis. Remember that the domain and range of the graph may be larger than the values seen if the graph extends beyond the area that is visible.

Consider the function y = f(x), which has the independent variable x and the dependent variable y. A value for x is said to be in the domain of a function f if it successfully allows the production of a single value y using another value for x.

If m FH = (31x + 3°), m GH = (33x + 3°) and m ∠FHG = (28x − 3°) then the measure of ∠FGH is 48°.

Given: m FH = (31x + 3°), m GH = (33x + 3°) and m ∠FHG = (28x − 3°)

Based on the above information, we get

m FG = 2(m ∠FHG) = 2(28x - 3)°= (56x - 6)°

The arcs in the circle add up to 360 degrees, then

m FG + m FH + m GH = 360°

120x = 360°

x = 3

Substitute the value of x in  m ∠FHG in we get

28(3) - 3 = 81°

The measure can be found using the triangle sum theorem (all angles in a triangle must add up to 180°).

Firstly, it is known that ∠GFH would be an inscribed angle if the chord from F to G is drawn, and the arc GH would be twice its measure.

m GH = 33(3) + 3 = 102°

Half of that would be m ∠GFH = 51°

According to the triangle sum theorem all angles of the triangle must add up to 180°:

Therefore, m ∠GFH+ m ∠FGH +m ∠FHG= 180°

m ∠FGH = 48°

Therefore, the measure of ∠FGH is 48°.

The complete question is:

Equation of a Straight Line

5.2     Solve   5y-92x-4459  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  5y-92x-4459  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 4459/5 so this line "cuts" the y axis at y=891.80000

 y-intercept = 4459/5  = 891.80000

Calculate the X-Intercept :

When y = 0 the value of x is 4459/-92 Our line therefore "cuts" the x axis at x=-48.46739

 x-intercept = 4459/-92  = -48.46739

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 891.800 and for x=2.000, the value of y is 928.600. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 928.600 - 891.800 = 36.800 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = 36.800/2.000 = 18.400

Geometric figure: Straight Line

 Slope = 36.800/2.000 = 18.400

 x-intercept = 4459/-92 = -48.46739

 y-intercept = 4459/5 = 891.80000

The equation of the line y = -3x + 17 would have a graph that is shown in the diagram attached below.

Given that the line y = -3x + b goes through the point B(5, 2), it means that the slope (m) of the line would be -3, while the line would intercept the y-axis at b.

To find the value of b, substitute (x, y) = (5, 2) into y = -3x + b:

2 = -3(5) + b

2 = -15 + b

16)a)4/13

b)8/13

c) 7/13

Here,  slope is 0 and y-intercept is zero too as line y=0

A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.

The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.  

Therefore,

m =  y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.

Be aware that tan ∅ = y/x

We also refer to this tan as the line's slope

We know that the equation for slope(m) and y - intercept(c) of a line is given by :

y = mx + c

As here y is 0

then, 0 = (0)x + 0

Therefore, slope is 0 and y - intercept is zero too

An arithmetic progression or arithmetic sequence ( AP ) is a sequence of numbers such that the difference between the consecutive terms is constant.

From the given information:

a₁ = -8

an = an-1+4

Then

second term = -8+4

second term = -4

And

Third term = -4+4

Third term = 0

And

Fourth term = 0+4

Fourth term = 4

And

Fifth term = 4+4

Fifth term = 8

And

Sixth term = 8+4

Sixth term = 12

And

7th term = 12+4

7th term = 16.

So, In the A.P. Series the 7th term is a 16.

Answer:

Perimeter = 2(Length + Width)     | Formula for perimeter

102 = 2(3m + m)                             | Plug in value of length and width

102 = 2(4m)                                    | Combine like terms

102 = 8m                                        | Distribute 2

8m = 102                                        | Flip LHS and RHS

m = 12.75m                                    | Divide by 8 on both sides

Answer m = 12.75 ft

Both Fahrenheit and Celsius scales will have the same reading at temperature -40⁰.

The equation to convert temperature reading from Celsius to Fahrenheit degree is:

     F = (9/5) C + 32

Where:

F = Fahrenheit reading

C = Celsius reading

The equation tells us that the ratio of increment in Fahrenheit to Celsius scale is 9 : 5, and there is an offset 32 degree in Fahrenheit scale.

Suppose a specific temperature has the same number reading on both scales, then:

F = C

Substitute this into the equation:

F = (9/5) C + 32

C = (9/5) C + 32

C - (9/5) C = 32

-4/5 C = 32

C = 32 . (-5/4) = -40

Hence, both Fahrenheit and Celsius scales have the same reading at temperature -40⁰.

The order from least to greatest is negative 7.7 repeating, negative seven and one sixth,  forty-four sixths and square root of 60

To determine the order from least to greatest is to arrange the values in an ascending order.

Given the values as;

This is expressed as;

√60 = 7. 75

-7. 7

44/ 6 = 7. 33

-7 1/6 = -43/ 6 = -7. 17

The order from least to greatest is -7. 7, -7. 17 , 7. 33 and 7. 75
