Answer:
D
Step-by-step explanation:
y_2 - y_1 / x_2 - x _1
4 - 2 / 3 - (-1) = 2/4 = 1/2
y +4 = 1/2 (x + 3) distributive property
y + 4 = 1/2x + 1.5
y= 1/2x - 5/2 subtraction (you subtract 4 from both sides) (-5/2 = -2.5)
therefore your equation is y = 1/2x - 5/2
hope this helps :)
Step-by-step explanation:
Using Binomial Expansion,
(x + y)³
= 3C0 * x³ + 3C1 * x²y + 3C2 * xy² + 3C3 * y³.
Therefore the coefficient of xy² is 3C2 = 3.
2a - b....a = 2 and b = 3
2(2) - 3 =
4 - 3 =
1

Number 4
Step-by-step explanation:
Option B would yield more in the short term but after Option A surpasses it, it would become more profitable.
Answer:
The amount of punch mix to use is 3/4 gallons
Step-by-step explanation:
Let
x ----> parts of water
y ---> parts of punch mix
we know that
----> equation A
That means ---> The parts of water is 8 times the parts of punch mix
If we have 6 gal of water
then
substitute in the equation A
solve for y
Simplify
therefore
The amount of punch mix to use is 3/4 gallons
