Answer:
10 hours
Step-by-step explanation:
f(h) = 15h + 75 = 225
subtracting 75 from both sides and simplifying:
15h +75-75 = 225-75 =150
15h = 150
Dividing both sides by 15:
15h/15 = 150/15
h = 10 hours
Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (5, - 3) and (x₂, y₂ ) = (- 9, - 6)
m = 
= 
=
The answer is 15. There are more girls than boys. 27 divided by 2 is 13.5. As the ratio is 5:4 the number of girls must be higher than 13.5, which cancels out 12 and 9. 54 is too great so the answer is 15.
yah it's not probably it's not 2 mmmm
9 because 9⁴ gives you that result, you can try on a calculator ;)
