5n + 4 = 39
5n = 39 -4
5n = 35
n = 35:5
n = 7
The function's input value is 2.
f(x) = 2x² + 3x + 5
f(x) = 2(2)² + 3(2) + 5
f(x) = 2(4) + 6 + 5
f(x) = 8 + 11
f(x) = 19
Answer:
x=-3
Step-by-step explanation:
This is a one step solution all you do is divide 5 into -15
-15/5 = -3
so -3 = x
Answer:
x ≤ 0
Step-by-step explanation:
2x² ≤ 0
2x² / 2 ≤ 0 / 2
x² ≤ 0
x²/ x ≤ 0 / x
x ≤ 0
