The work shows the first steps of writing a partial fraction decomposition. Which equations can be used in a system of equations to solve for the unknowns. Check all that apply.

A = 2

–6A + B = 2

3A – B + C = 1

B = 0

9A – 3B + C = 1

It's the first and last one

What is the value of y? round to the nearest tenth

Arianna is buying plants for her garden. she buys 15 flowering plants for $96. pink flowering plants sell for $8, and purple flowering plants sell for $5. how many pink flowering plants did arianna buy? i figured out the answer! the answer is 7. 8x +5y = 96 plug in 7 for x 8 (7) + 5y = 96 56 + 5y = 96 subtract 56 from both sides 5y/y = 40/5 y = 8 she bought 7 pink and 8 purple plants

Factor the following expression. 27y3 – 343 a. (3y + 7)(9y2 + 2ly + 49) b. (3y – 7)(9y2 + 2ly + 49) c. (3y – 7)(932 – 217 + 49) d. (3y + 7)(92 – 2ly + 49)
