Answer:

So you have the multiplication and substitution right. It's just the subtraction.

Step-by-step explanation:

Now, the equation was y = 4x - 2

In the first one x = -3

So it will be 4(-3) - 2

Note: Anytime you see a bracket it means multiplication.

4× -3 = -12 and

-12 - 2 = -14

This is because a negative number minus another number is always negative.

And when dealing with negative numbers you add them but you negate the answer.

For example;

The second one will be -8 - 2

And 8 + 2 = 10

But since the numbers are negative we just negate the 10 making it - 10.

I hope this helps

vova2212 [387]

First add 24.95 and 35.99. You get 60.94 (Remember This!)

Now you take 49.95 divided by 2. you should get: 24.975.

add 24.975 with 60.94. You get 85.915

take 85.915 and multiply it by 0.15. You get 12.88725.

Subtract 85.915 by 12.88725. You should get 73.02775.

Now multiply that by 0.045. you should get 3.28624875.

Add that onto 73.02775, and you get 76.31399875.

Round that to the nearest hundredth, and your done! (The answer is: 76.31!)

The answer will be the B.
