Answer:
2:10 2/10 2 to 10 10:2 10/2 10 to 2 12:1 12/1 12 to 1
Step-by-step explanation:
F(x) = 4.25x + 50
for 6 hrs....x = 6
f(6) = 4.25(6) + 50
f(6) = 25.50 + 50
f(6) = 75.50 <==
Answer:
y = 3x² - 6x - 72
Step-by-step explanation:
Since the roots are x = - 4 and x = 6 then the factors are
(x + 4) and (x - 6) and the quadratic function is
y = a(x + 4)(x - 6) ← a is a multiplier, in this case 3, so
y = 3(x + 4)(x - 6) ← expand factors and distribute by 3
y = 3(x² - 2x - 24)
y = 3x² - 6x - 72
For this case we have the following equation:
We apply distributive property to the terms within parentheses:
We subtract 
and on both sides of the equation:
We subtract 
on both sides of the equation:
We divide by 3 on both sides of the equation:
