Answer:

y = 3x

Step-by-step explanation:

the equation of a line passing through the origin is

y = mx ( m is the slope )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (2, 6) ← 2 points on the line

m = [tex]\frac{6-0}{2-0}[/tex] = [tex]\frac{6}{2}[/tex] = 3

Answer:

False

Step-by-step explanation:

The rate of change/slope of the linear equation is 8.

The y-intercept is the point where x has no value and y does.

And in the linear equation y = 8x+3, the y-intercept is 3.

According to the question, to calculate the probability of the event which states that tossing a coin to get either head or tail

The total number of a coin is [tex]1[/tex]

And total number of possibilities are {H,T}

Therefore, the total number of favorable outcomes in which either head or tail can come: [tex]1[/tex]

As per question, the probability can be written as:

P(h or t) = P(h) + P(t)

            [tex]= \frac{1}{2} +\frac{1}{2} =1 = 100%[/tex]

Hence, the probability of getting either head or tail is [tex]1[/tex].

The given event is mutually exclusive because it has [tex]100[/tex] percent which is close to tenth of a percent. And these two events cannot happen at the same time also, so they are mutually exclusive.

The equation of the circle for a circular irrigation field with radius 12 and center at (7 , -10) is (x - 7)^2 + (y + 10)^2 = 144.

The general form of the equation of  circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.

Given the radius and center of the circular irrigation field, substitute these values to the general form of the equation of the circle.

(x - h)^2 + (y - k)^2 = r^2

where (h , k) = (7 , -10)

r = 12

(x - 7)^2 + (y - -10)^2 = 12^2

The solution to given equation 2x / 3 - 1/2 = 2x + 5/6 is x = -1

In this question, we have been given an equation.

2x / 3 - 1/2 = 2x + 5/6

We need to find the solution of given equation.

⇒ 2x / 3 - 1/2 = 2x + 5/6

⇒ (4x - 3)/6 = (12x + 5)/6

⇒ 4x - 3 = 12x + 5

⇒ 4x - 12x = 5 + 3

⇒ -8x = 8

⇒ x = -1

We need to check above solution.

so, substitute x = -1 in LHS of given equation.

LHS

= 2(-1) / 3 - 1/2

= -2/3 - 1/2

= -(2/3 + 1/2)

= -[(4 + 3)/6]

= -7/6

Now, substitute x = -1 in RHS of given equation.

RHS

= 2(-1) + 5/6

= -2 + 5/6

= (-12 + 5)/6

= -7/6

For x = -1, LHS = RHS

Therefore, the solution to given equation 2x / 3 - 1/2 = 2x + 5/6 is x = -1

The probability for the arrow that land in the number 3 is 1/8.

Probability:

Basically, the word probability means the possibility of occurring the required event.

Given,

The spinner is divided into 8 equal sections.

Here we need to find if the arrow lands on a number, what is the probability that it will land on 3.

Let us consider that the spinner has 8 equal-sized sections numbered 1 to 8.

Since the sections have equal size, each section is equally probable.

The probability of falling on each section is therefore 1/8.

We know that, in the 8 sections,

There is only one 3 in this list.

So, the possibility of the event = 1

Hence, probability is

=> 1/8

Therefore, the probability for the arrow that land in the number 3 is 1/8.

Step-by-step explanation:

The required distance between the third and first fret would be 64.390 mm.

Arithmetic functions are defined as adding, subtracting, dividing, and multiplying built-in functions.

- Subtraction operation: calculates the difference between the right-hand and left-hand operands.

for example 4 -2 = 2

+ Addition operation: on either side of the operator, additional significances are added.

For example 4 + 2 = 6

We have been given that the distance between the first and second frets is 33.641 mm.

The distance between the second and third frets is 31.749 mm.

So the distance between the third and first fret will be:

⇒ 33.641 + 31.749

Apply the addition operation, and we get

⇒ 64.390 mm

Therefore, the required distance between the third and first fret would be 64.390 mm.

Answer:

Let r be the number of rides and g be the number of games.

2.50g + 4.00r = 52.50

r = 2g

The equations are 2.5g +4r = 52.5 and g=2r.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

Cost of game = $2.50

Cost of ride = $4

let g be the number of games

and, let r be the number of rides taken

total they played = $52.50

So, the equation can be

2.5g +4r = 52.5

and,  number of rides she went on is twice the number of games she played.

So, g = 2r

Using the definition of slope, the points (3 , -5), (-3 , 3), and (0 , 2) are not collinear.

Three or more points are said to be collinear if they lie on a single straight line.

To determine whether the given points are collinear, use the definition of slope. The slope, m, determines the steepness of a line. It can be measured by the vertical distance from one point to another divided by the horizontal distance of the same points.

m = (y2 - y1)/(x2 - x1)

Getting the slope of each pair of points:

(3 , -5) and (-3 , 3)

m = (y2 - y1)/(x2 - x1)

m = (3 - -5)/(-3 - 3)

m = 8/-6

m = -4/3

(-3 , 3) and (0 , 2)

m = (y2 - y1)/(x2 - x1)

m = (2 - 3)/(0 - -3)

m = -1/3

(3 , -5) and (0 , 2)

m = (y2 - y1)/(x2 - x1)

m = (2 - -5)/(0 - 3)

m = 7/-3

m = -7/3

Since collinear points lies on the same line, the slope of any pair of points should be the same. Since the slopes of each pair of points is not equal with each other, then they are not collinear.

Answer:

x = 2, x = -6

Step-by-step explanation:

Given quadratic function in vertex form:

[tex]f(x)=(x+2)^2-16[/tex]

The zeros of a function occur when f(x) = 0:

[tex]\implies (x + 2)^2 - 16 = 0[/tex]

Add 16 to both sides:

[tex]\implies (x + 2)^2 - 16+16 = 0+16[/tex]

[tex]\implies (x + 2)^2 =16[/tex]

Square root both sides:

[tex]\implies \sqrt{ (x + 2)^2} =\sqrt{16}[/tex]

Subtract 2 from both sides:
