Find the rate of change for the direct variation using the formula y = kx

Solve for k: 10 = k2

K = 10/2

K = 5

Now solve for y when x is 8:

Y = 5(8)

Y = 40

Answer:

the answer is y=30x

Step-by-step explanation:

however many inches times 30 is the consistent answer to the equation    

Answer:

y=30x

Step-by-step explanation:

We can start out by writing our slope-intercept form equation: y=mx+b. In this case, our y-intercept is 0, so we can write y=mx.

Let's find the slope. We can take the points (1,30) and (2,60). We can use the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] to find our slope. Plug these values in, and we get [tex]\frac{60-30}{2-1}[/tex]. Evaluate this, and our slope is 30. So, our equation is y=30x.

12 + 3 = 15

Angle 1 + Angle 2 = 180°

(7x)° + (x + 20)° = 180°

(8x + 20)° = 180°

8x = 180 - 20

8x = 160

x = 160/8

x = 20

7(20) = 140° and 20 + 20 = 40°

Answer: 40° and 140°

Which proportion can be used to find the arc length, s, in units?

Answers

Answer:

Option B

Step-by-step explanation:

Formula to be used to calculate the length of an arc,

Length of arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]

Here, θ = Angle subtended at the center by the arc

r = radius of the circle

By substituting values in the formula,

s = [tex]\frac{150}{360}(2\pi )(42)[/tex]

[tex]\frac{s}{2\times 42\pi }=\frac{150}{360}(\frac{2\times 24\pi }{2\times 24\pi } )[/tex]

[tex]\frac{s}{84 \pi }=\frac{150}{360}[/tex]

Therefore, Option B will be the answer.

Rewrite this expression without using absolute value
I nEeD hElP qUiCk!

Answers

Answer:

Step-by-step explanation:

Normally when you are doing an absolute value question, you do it like this

y = abs(4x - 12) and you write the absolute value equation as

y = 4x - 12 and

y = - 4x + 12

These two are shown in graph27a

to show both wings of the absolute value curve

This is slightly different.

I think you would write this as

y = 4x - 12 {r <3} where the restriction is outside the equation written with curly brackets. You should see both graphs together. The discussion of r<3 is shown in graph 27b

Answer:

Step-by-step explanation:

Since this triangle is a right triangle, the two acute angles are always going to be complementary (adding up to 90 degrees). So we can set up an equation: 2x+3x+5=90. Solve this and we get x=17.
