Answer:

b. y = −0.5x + 5.5

Step-by-step explanation:

Well first we need to find the slope of line CD.

To do that we'll use the following formula,

\frac{y^2-y^1}{x^2-x^1}

We'll use the points (1,1) and (3,5)

So y2 is 5 y1 is 1 so 5-1 = 4

3-1 = 2

<u>Slope = 2x</u>

If the slope of line CD is 2x we can cross out choices C and D.

Two lines that are perpendicular to each other have reciprocal slopes,

meaning is the slope of line CD is 2 then its perpendicular lines slope should be -.5.

If the perpendicular line goes through point (-1,6), the y intercept would be, 5.5.

Look at the image below ↓

<em>Thus,</em>

<em>the answer is option b. y = −0.5x + 5.5.</em>

<em>Hope this helps :)</em>

What is the slope of the line? Please explain your answer.

The answer is D

At first glance we can see the slope of the line is negative. Automatically A and C are incorrect. Slope is y/x, we go 1 space down and 5 spaces to the right. (Run over rise)

Taylor ran 2 1/4 miles and walked 2 4/5 miles. How far did she run and walk
irinina [24]
Okay. So, we should convert fractions to the least common denominator, which is 20. That would be 2 5/20 and 2 16/20. Add both of those numbers up to get 5 1/20. Taylor ran and walked 5 1/20 miles.

How do you make 'a' the subject of the formula: ab - cd = ac
xxTIMURxx [149]
First bring all terms in 'a' to the left side of the formula by subtracting ac from both sides

ab - ac - cd = ac - ac 
ab - ac - cd = 0
now add cd to both sides
ab - ac -cd + cd = cd
ab - ac = cd
now factor the left side by taking out the 'a' 
a(b-c) = cd
now divide both sides by (b-c)
a = cd / (b-c)
done
