Answer:
Step-by-step explanation:
First let's re-write the equation:
f(x) = 3x² - 5x + 4
If f(-2). then we can re-write the equation as:
f(-2) = 3(-2)² - 5(-2) + 4
We must solve for exponent first: (-2)² = 4
f(-2) = 3(4) - 5(-2) + 4
Then solve for multiplication:
f(-2) = 12 + 10 + 4
Finally addition:
f(-2) = 26
that means that in a function, if X = -2, then F is equal to 26
Answer:
x = 31
So 2x-7 = 55
x + 4 = 35
Step-by-step explanation:
I think 8.0km is the answer
When multiplying two negative numbers the product will be positive. For example, 5*3=15 and -5*-3=15, but 5*-3=-15 likewise -5*3=-15.
Answer:
2x² + 3x - 5
Step-by-step explanation:
(2x + 5)(x - 1)
2x² - 2x + 5x - 5
2x² + 3x - 5
