To find the difference of the given expression, first step is to get rid of parenthesis. So, distribute negative sign to each terms of the second parenthesis. Hence,
(9x² + 10x + 4) - (9x² + 5x - 1)
= 9x² + 10x + 4 - 9x² - 5x + 1.
= (9x² - 9x²) +(10x - 5x) + (4 + 1) Group the like terms.
= 0 + 5x + 5 Combine the like terms.
= 5x + 5.
So, first choice is correct.
Hope this helps you!

Step-by-step explanation: What is 5 pounds of aluminum cans worth?
f is defined as
• f(4) = -8
• f(-7) = -1
• f(-5) = -4
This means the inverse is defined as
• f ⁻¹(-8) = 4
• f ⁻¹(-1) = -7
• f ⁻¹(-4) = -5
Answer:
19

19-10=9
Answer:
D)x = 2y ^ 2
Step-by-step explanation:
y = 2x ^ 2
To find the inverse exchange x and y
x = 2 y^2
Then solve for y
Divide by 2
x/2 = 2y^2 /2
x/2 = y^2
Take the square root of each side
±sqrt(x/2) = y
