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
Given:
4x + 7 = 23
Let's solve for x.
First Step:
Subtract 7 from both sides
4x + 7 - 7 = 23 - 7
4x = 16
Next Step:
DIvide both sides by 4
ANSWER:
x = 4
Your answer would be 8 when you do all the calculations
Remember that you can do anything ot an equaiton as long as you do it to both sides
-8+x=0
add 8 to both sides
8-8+x=0+8
0+x=8
x=8
answer is B. 8
