You’d set up a proportion. I did 25/15=7x-40/18.
Then you would cross multiply to get 15(7x-40)=450
Distribute the 15.
105x-600=450
Add 600 to both sides, so the -600 cancels out.
Then you’re left with 105x=1050
Divide both sides by 105 and you get x=10
Could be y=8x + 16?
The gradient is 8 bcause each time x increases by one y increases by 8
Answer:
B
Step-by-step explanation:
A give me 2'zero
b give me 9'zero
c give 8'zero
d gives 5 zero
e give me 4'zero
for example it give me two zero it 100
or if five 5 zero it 100000
hope this helps
