Answer:
3/b^4
Step-by-step explanation:
b^0 = 1
3b^(-4) / b^0 = 3b^(-4) / 1 = 3b^-4
Since you are instructed to write only positive exponents, the answer is 3/b^4
Answer:
8x² + 8
Step-by-step explanation:
Given
(x² + 3)² - (x² - 1)² ← expand both factors using FOIL
= + 6x² + 9 - ( - 2x² + 1) ← distribute by - 1
= + 6x² + 9 - + 2x² - 1 ← collect like terms
= 8x² + 8
Answer:
C. 873.67
Step-by-step explanation:
399.17 + 150 + 69 + 200 + 55.5 = 873.67
Part A: The shading is in between the lines. The line for y<4x-2 is dotted, while the line for y<span>≥(-5/2)x-2 is solid</span>. The solution area is below the line y=4x-2 and above the line y=(-5/2)x-2.
Part B: (-2,-2) is not in the solution area. We can plug (-2,-2) into the inequalities: -2<4(-2)-2, and -2<(-5/2)(-2)-2. However neither of these are true so it is not a solution.
