How do you find the correct equation? Follow these steps.
First, plug 0 in for X and solve for Y . Does the y value match what is on the graph? 0 in this case?
a. 0 = -2(0) True - This could be an answer
b. 0 = 0 + 4 False - This cannot be an answer
c. 0 = 2(0) True - This could be an answer
d. 0 = 0 - 4 False - This cannot be an answer
Now we are down to 2 possible answers A and C. Now take another point on the line, say x=-2 and repeat, does the answer match what is on the graph? (4).
a. 4 = -2(-2) True
c. 4 = 2(-2) False
As only A matches, A must be the answer. With graphing problems, when you have to find the correct equation, always choose X=0 as the first point (assuming it has a Y value) and eliminate answers. I hope this helps.
Answer: A and D
Step-by-step explanation:28 x 43=860
20 x 3=60
860-60=800
20 x 40=800
all of this equals 860
Answer:
Step-by-step explanation:
<u>Distance between two points</u>
Substituting points into the distance formula and solving for d:
12) 10.77 + 2.09 + 0.75 = 13.61
13.61 x 1.07 = $14.56
total amount = $14.56
14) C shows the possible combinations
