Answer:
y = -2x^2 -4x +1
Step-by-step explanation:
y-3 = -2 (x+1)^2
Foil (x+1)^2
(x+1)(x+1) = x^2 +x+x+1 = x^2 +2x+1
Substitute this back in
y-3 = -2(x^2 +2x+1)
Distribute
y-3 = -2x^2 -4x -2
Add 3 to each side
y-3+3 = -2x^2 -4x -2+3
y = -2x^2 -4x +1
Answer:
Inequality: 8p ≤ 50
Answer: p ≤ 6
Step-by-step explanation:
Step 1. Write an equation
$8 per person = 8p (where 8 is the cost per person and p is the number of people)
8p ≤ 50
Step 2. Solve
8p ≤ 50
÷8 ÷8
p ≤ 6.25 ≈ p ≤ 6 (your final answer is 6 because you cannot have 1/4 of a friend)
Step-by-step explanation:
(-10-5)/([-5-(-1)]=
-15/-4=15/4=3.75
The probability of not drawing one is 6/11
Answer:
Step-by-step explanation:
1) Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd.
2) Collect like terms.
3) Simplify.
Therefor, the answer is, 10x^3 - 26x^2 - 12x.
