(x⁴ -11x² + 30)(x +2) = (x⁴ -11x² + 30)*x + (x⁴ -11x² + 30)*2
= x⁴*x - 11x²*x + 30*x + x⁴*2 - 11x²*2 + 30*2
=x⁵ - 11x³ + 30x + 2x⁴ - 22x² + 60
= x⁵ + 2x⁴ - 11x³ - 22x² + 30x + 60

What is an equation for the line that passes through points (2.-3) and (1, 2)? (+ 3) = -5(x - 2) b. (y - 3) = 5(x ! 2) (y - 3) = -5(.x + 2) d. (+3) = S(x - 2)
Answers
Answer:
A. y + 3 = -5(x - 2)
Step-by-step explanation:
The slope is:
2 - (-3) / 1 - 2 = 5 / -1 = -5.
Then, put it in point slope form (which was [tex](y - y1) = m(x-x1)[/tex] where m is the slope, and (x1, y1) is the coordinate point it gives you. You can use m = -5, x1 = 2 and y1 = -3.)
y + 3 = -5(x - 2)

Marcy is baking blueberry pies to sell at her bakery. She starts with 8 3/4 cartons of blueberries, of which she uses 1/2 for the first batch of pies. How many cartons of blueberries does Marcy use for the first batch of pies?
Answers
Answer: Marcy used [tex]\dfrac{35}8[/tex] cartons of blueberries for the first batch of pies.
Step-by-step explanation:
Given: Quantities of blueberries = [tex]8\dfrac34[/tex] cartons
[tex]=\dfrac{8\times4+3}{4}=\dfrac{35}{4}[/tex] cartons
Blueberries used for first batch = [tex]\dfrac12[/tex] of (Total)
[tex]=\dfrac12\times\dfrac{35}{4}\\\\=\dfrac{35}{8}[/tex]cartons
Hence, Marcy used [tex]\dfrac{35}8[/tex] cartons of blueberries for the first batch of pies.

Answer:
The answer to the system of equations is x = 2 and y = -1
Step-by-step explanation:
We can substitute the variables and see how they work with the equations.
2 (-1) = (2) - 4
-2 = 2 - 4
-2 = -2
4 (2) + 3 (-1) = 5
