Question

What is the answer to b in #10

Answer 1

Answer:

X=5 (Or (5,0))

Step-by-step explanation:

The Y intercept is when X=0

The X Intercept is when Y=0

Our equation is y=-4200x+21000

So let's rewrite it... First subtract 21,000 (Also, remember Y is 0)

0-21000=-4200x

-21000=-4200x

Now to get X alone, divide -21000 by -4200

This will give us 5=x, which is the same as x=5. There is your answer!
