Cube root of 128 = 5.0396842 mm
Answer:
(21, 2 )
Step-by-step explanation:
Given the 2 equations
y = - x + 9 → (1)
y = x - 12 → (2)
Substitute (2) into (1)
x - 12 = - x + 9 ( add x to both sides )
x - 12 = 9 ( add 12 to both sides )
x = 21
Substitute x = 21 into either of the 2 equations and evaluate for y
Substituting into (2)
y = × 21 - 12 = 14 - 12 = 2
Solution is (21, 2 )
<h3><u>(f - g)(x) = -2x^2 + 10x</u></h3>
x^2 + 6x - 1 - (3x^2 - 4x - 1)
Distributive -1 to each term in parentheses.
x^2 + 6x - 1 - 3x^2 + 4x + 1
Combine like terms.
-2x^2 + 10x
