Answer:

For the first one it is y = -5x because for it to be direct it can't have a b-intercept. it must start at 0.

Second question: y2 - y1/x2 - x1

13-(-8)/(-4)-3

21/(-7)

-3 is the slope

y= -3x + b

13 = -3(-4) + b

13 = 12 + b

12 - 13 = b

b = -1

y=-3x-1

0 = -3x - 1

1 = -3x

1/-3 = -3x/-3

x= -1/3

y=-3x-1

y=-3(0)-1

y= -1

The answer to the 3rd question is y = 1x + 2 because the rise over run is one and the line crosses the y-intercept at 2.

I am not sure if these answers are correct.

Answer: A forest covers 41,000 acres. A survey finds that 0.4?% of the forest is? old-growth trees. How many acres of? old-growth trees are? there?

Alrighty, let me help you out, make things easier! The ANSWER is going to be 24,600, by this process, just take 41,000 and multiply that by 0.4. that gives you 16400, and since you are trying to find a portion of the forest, you subtract 16400 from 41,000 total acres. Hope that helps!

Write the sentence as an equation. 373 plus the product of 169 and u is t Type a slash ( / ) if you want to use a division sign.
Masja [62]
373 + (169 * u ) = t

The equation above is your answer.

Just remember "product" means the answer to a division problem and "is" usually means that you should insert an equals sign.
