Write an equation of the line graphed in slope-intercept form using the variables x and y.

Answer:

y = -0.5x + 5

Step-by-step explanation:

To find the slope you can look at the graph at tell that the line goes down 2 and to the right 1. It looks like this in fraction form -1/2. If we divide -1 by -2 we get -0.5. This is a downward slope so the slope is negative. The y-intercept is where the line intercepts the y-axis which is 5. Slope-intercept form is y = mx + b.

Zoe counts 5 times as many black kittens as white kittens for sale at the pet store. she counts a total of 25 kittens how many m

malfutka [58]

Let us say that:

a = black kittens

b = white kittens

We know that:

a = 5 b

a + b = 25

Therefore:

5 b + b = 25

6 b = 25

b = 4.17

But we cannot have a fraction value for the number of kittens, so round off:

b = 4

So a is:

a = 25 – 4 = 21

<span>Hence Zoe counts additional 1 black kitten.</span>

If 7x=3y and 5y=7z then X/Z?

Aleks04 [339]

Answer:

3/5=x/z

Step-by-step explanation:

7x=3y

7(3)=3(7)

21=21

5y=7z

5(7)=7z (plug in the seven from the first step)

35=7z

then divide both sides by 7

5=z

therefore, X/Z=3/5

A sector with a radius of 8 cm has an area of 56pi cm2. What is the central angle measure of the sector in radians?

Maurinko [17]

Answer:

$\frac{7\pi}{4}$ .

Step-by-step explanation:

Given information:

Radius of circle = 8 cm

Area of sector = $56\pi\text{ cm}^2$

Formula for area of sector is

$A=\dfrac{1}{2}\theta r^2$

where, r is radius and $\theta$ is central angle in radian.

Substitute $A=56\pi$ and r=8 in the above formula.

$56\pi=\dfrac{1}{2}\theta (8)^2$

$56\pi=\dfrac{64}{2}\theta$

$56\pi=32\theta$

$\dfrac{56\pi}{32}=\theta$

$\dfrac{7\pi}{4}=\theta$

Therefore, the measure of the sector in radians is $\frac{7\pi}{4}$ .
