Answer:
x = 1 if the perimeter is 42
Step-by-step explanation:
Given
s = 4x + 10
when Perimeter = 42, what is x?
Solution
Perimeter = 3s
Perimeter = 3(4x +10) Remove the brackets
Perimeter = 12x + 30
Let the Perimeter = 42
42 = 12x + 30 Subtract 30 from both sides
42-30 = 12x + 30-30 Combine
12 = 12x Divide by 12
12/12 = 12x/12
x = 1

The general form of a linear equation is y - y1 = m(x - x1) then the point-slope form exists y - 5 = 3(x - 9)
What is point-slope form?The general structure of a linear equation exists y - y1 = m(x - x1). It draws attention to the line's slope and one of the line's points (that exists not the y-intercept).
Given: (x1, y1) = (9, 5) and (x2, y2) = (8, 2)
The point-slope form exists given by,
y - y1 = m(x - x1)
m = (y2 - y1)/(x2 - x1)
substitute the values in the above equation, we get
m = (2 - 5)/(8 - 9)
m = 3
The value of m = 3.
y - 5 = 3(x - 9)

Which expression is equivalent to quantity negative three and one fourth times d plus three fifths end quantity minus quantity two and seven eighths times d plus seven tenths end quantity? negative forty nine over 8 times d minus one tenth forty nine over eight times d minus one tenth negative three eighths times d minus one and three tenths negative three eighths times d minus one tenth
Answer:
Step-by-step explanatio -3/8d-1 3/8
The expression "quantity negative three and one fourth times d plus three fifths end quantity minus quantity two and seven eighths times d plus seven tenths end quantity" or (-3 1/4d + 3/5) - (2 7/8d + 7/10) is equivalent to "negative forty nine over 8 times d minus one tenth" or -49/8d - 1/10.
An algebraic expression is a number, variable, or the combination of both and operational symbols.
To determine the equivalent of the expression "quantity negative three and one fourth times d plus three fifths end quantity minus quantity two and seven eighths times d plus seven tenths end quantity" or simply (-3 1/4d + 3/5) - (2 7/8d + 7/10), combine all like terms and perform the necessary operations.
(-3 1/4d + 3/5) - (2 7/8d + 7/10)
⇒ -3 1/4d + 3/5 - 2 7/8d - 7/10
⇒ (-3 1/4 - 2 7/8)d + 3/5 - 7/10
⇒ (-13/4 - 23/8)d + 6/10 - 7/10
⇒ (-26/8 - 23/8)d - 1/10
⇒ -49/8 d - 1/10
Hence, the equivalent expression is "negative forty nine over 8 times d minus one tenth" or -49/8d - 1/10.

COORDINATE GEOMETRY Find the distance from P to l .Line l contains points (0,-2) and (1,3) . Point P has coordinates (-4,4) .
According to the given statement the perpendicular distance form the point (-4,4) is 66.3.
What Exactly Is Coordinate Geometry?Coordinate Geometry can be used to define points in space. The primary axis labeled a x- and y-axes is defined first, and then the points were measured and labelled in relation to these points. Furthermore, numerous geometric forms such as a line, curve, circle, ellipse, and hyperbola can be plotted inside the coordinate axes and their attributes studied.
According to the given data:the equation for line ℓ.
Begin by finding the slope of the line through the given points,(0,-2) and (1,3):
m = (Y₂ - Y₁)/(x₂ - x₁)
= (3 - (-2))/(1 - 0)
= 5/1
= 5
The equation of the line using point (1,3) on the line:
Y - Y₁ = m(x - x₁)
putting value we get: (m = 5)
Y - (-2) = 5(x - 1)
Y + 2 = 5x - 5
Y = 5x - 3
The equation of the line w perpendicular to line ℓ through P(-4,4).
The slop of line l is 5. Write the equation of the line using point P(-4,4) on the line.
Y - Y₁ = m(x - x₁)
Y - 4 = 5(x - (-4))
Y - 4 = 5x + 4
Y = 5x + 8
Solve the system of equations to determine the point of intersection. Subtract both sides of (1) and (2) to eliminate y.
5x + 8 = 5x - 3
5x + 8 - 5x + 3 = 0
x = 11
putting the value of x to find y:
Y = 5x + 8
Y = 62
Applying the formula to find the distance of a points:'
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
d = √((11 - 4 )² + (62 + 4)²)
d = √(4405)
d = 66.3
According to the given statement the perpendicular distance form the point (-4,4) is 66.3.

Please help me with this.
Step-by-step explanation:
a)
high positive x (x going to +infinity) would create high positive y (also +infinity).
while high negative x (x going to -infinity) would create high negative y (also -infinity), x⁵ with its odd exponent is negative for negative x and positive for positive x.
the graph is showing just the opposite behavior.
so, it cannot be the right graph.
b)
the degree of the polynomial is the highest exponent of the input variable x. in our case : 5
a polynomial of degree n must have n zeros (or roots).
in our case we need 5 zeros. but there are only 3. no matter how we shift it up or down, the x-axis will not intercept it more than 3 times.
so it cannot be the right graph.

The postulate of equality or inequality that is illustrated is the transitive postulate of equality
How to determine the postulate of equality or inequality that is illustrated?The illustrated expression is given as
If 1/4 + 1/4 = 2/4 and 2/4 = 1/4 then 1/4 + 1/4 = 1/2
In the above expression, we do not have any inequality sign
This means that the expression is an equation i.e. equality
The transitive postulate of equality states that
if a = b and b = c, then a = c
The given equality expression illustrates the transitive postulate of equality
i.e.
If 1/4 + 1/4 = 2/4 and 2/4 = 1/4 then 1/4 + 1/4 = 1/2
if a = b and b = c, then a = c

Describe a sequence of translations, rotations, and
reflections that takes polygon P to polygon Q.
Use the digital tracing paper if it helps you with your
thinking?
The polygon P is translated and rotated respectively to obtain polygon Q.
A translation is a geometric transformation when each point in a figure, shape, or space is moved in a specific direction by the same amount. A translation can also be thought of as moving the origin of the coordinate system or as adding a constant vector to each point.
Each point in a figure is transformed into a rotation by rotating it a specific amount of degrees around another point.
ABCD and EFGH are polygons P and Q respectively.
We will briefly outline each step required to convert each Polygon P into its corresponding Polygon Q in this question.
In this case, there is translation along a vector between point A and point H.

Do invariant points sometimes, always, or never occur in a rotation? Explain your reasoning.
Points that map onto themselves are said to be invariant points. Invariant points can occasionally appear during a rotation.
Do rotations have invariant points?
The axis of rotation is a line of invariant points that defines the rotation of a three-dimensional figure in space. Since rotation does not alter the shape of the figure being rotated, it is referred to as an isometric transformation along with translation and reflection.Points that map onto themselves are said to be invariant points. Invariant points can occasionally appear during a rotation.
The point of rotation is invariant when a figure is rotated about that point. There are no invariant points in a rotation of a figure centered on a point that is not on the figure.
