Answer:
23
Step-by-step explanation:
Since it says f(x) that means that when we see f(-6) we are substituting x for -6.
This means that the equation will become
f(-6) = -3(-6) + 5
First multiply -3 and -6 (18)
f(-6) = 18 + 5
Next add 18 and 5 (23)
This means that f(-6) = 23
$9 + $9 + $9 + $9 + $9 + $3 = $48
5 + 5 + 5 + 5 + 5 + 1 = 26 hamburgers.
Hope that helps :)
Answer: c = 520
Step-by-step explanation:
f(2) = 578 means that when x = 2, the value is equal to 578. We will plug these knowns in and then solve for c.
Given:
f(x) = 4x³ + 7x² - x + c
Substitute:
578 = 4(2)³ + 7(2)² - (2) + c
Distribute:
578 = 4 * 2³ + 7 * 2² - 2 + c
Raise to the power of 3 and 2:
578 = 4 * 8 + 7 * 4 - 2 + c
Multiply:
578 = 32 + 28 - 2 + c
Add:
578 = 60 - 2 + c
Subtract:
578 = 58 + c
Subtract 58 from both sides:
520 = c
Reflexive property:
c = 520
