<h3>
Answer: 29</h3>
==========================================================
Explanation:
We replace every copy of x with -2. From there, use PEMDAS to simplify
y = 3x^2 + 17
y = 3(-2)^2 + 17
y = 3(4) + 17
y = 12 + 17
y = 29
Therefore, x = -2 pairs up with y = 29.
Put another way, the point (x,y) = (-2, 29) is on the function curve.
Answer:
4 vests
Step-by-step explanation:
Larry has 9 yards of fabric, in which 2 are needed to make a vest.
Divide 9 with 2: 9/2 = 4.5
However, note that you cannot have half a vest, so you must round down.
4.5 becomes 4.
4 vests is the maximum Larry can make with 9 yards of fabric.

Answer:
Jamie has 44 pairs of shoes
Step-by-step explanation:
Let
Jamie= x pairs of shoes
Suzie= 33 less than twice the amount of shoes Jamie has
2x - 33 = 55
Solve:
2x - 33 = 55
Collect like terms
2x = 55 + 33
2x = 88
Divide both sides by 2
2x / 2 = 88 / 2
x = 44
Jamie = x = 44 pairs of shoes
Therefore, Jamie has 44 pairs of shoes
Answer:
Given: BD is an altitude of △ABC .
Prove: sinA/a=sinC/c
Triangle ABC with an altitude BD where D is on side AC. Side AC is also labeled as small b. Side AB is also labeled as small c. Side BC is also labeled as small a. Altitude BD is labeled as small h.
Statement Reason
BD is an altitude of △ABC .
Given △ABD and △CBD are right triangles. (Definition of right triangle)
sinA=h/c and sinC=h/a
Cross multiplying, we have
csinA=h and asinC=h
(If a=b and a=c, then b=c)
csinA=asinC
csinA/ac=asinC/ac (Division Property of Equality)
sinA/a=sinC/c
This rule is known as the Sine Rule.
