Answer:
3y is the expression that represents the product of 3 and y
Answer: the heart works to pump through the body systems
Answer:
y = - 2(x - 1)² + 18
Step-by-step explanation:
- 2x² + 4x + 16 ← factor out - 2 from the first 2 terms
= - 2(x² - 2x) + 16
using the method of completing the square
add/subtract ( half the coefficient of the x- term)² to x² - 2x
= - 2(x² + 2(- 1)x + 1 - 1) + 16
= - 2(x - 1)² + 2 + 16
= - 2(x - 1)² + 18 ← in vertex form
16a+1 is the answer to your question
First, convert 3 into a fraction with denominator 8.
(3 pizzas)(8/8 pizzas)=24/8 pizzas
Then, divide 24/8 pizzas by 2/8 pizzas per 1 person.
(24/8 pizzas)(2/8 pizzas/person)
Dividing by a fraction is the same as multiplying by the reciprocal:
(24/8)/(2/8)=(24/8)×(8/2) the 8s cancel and you are left with 24/2=12
3 pizzas will feed 12 people.
