Answer:
25
Step-by-step explanation:
Divide 500/20
29% = 0.29
Multiply 1.89 with 0.29
1.89 x 0.29 = 0.5481
Note that it is a markdown, so subtract 0.55 (rounded) with 1.89
1.89 - 0.55 = 1.34
The spark plug now costs ~ $1.34

Answer:
1. Option A
2. Option B
Step-by-step explanation:
I would like to elaborate on the answer to the second question, since the first answer is actually option a. Why? The question asks for a parametric equation, not set, so it would be choice a.
2. x=3t + 5 - isolate t
t=(x-5)/3 - substitute into the second equation
y = [(x-5)/3]^2 - 1
your solution is option b
Answer:
Yes, because the x's do not have more than one y.
Step-by-step explanation:
x y
0 0
5 10
6 12
10 20
(That's meant to be a table). Looking at the x and y table values, you can see that none of the x's have two y's. So, this relation is a function.
