One solution!
Step-by-step explanation:
If we make a graph of the given equations, the lines will intersect at a point. We know that whenever lines intersect, it means the equations have one solution or a unique solution.
Answer:
406 pieces. If you multiply 58 times 7 you get 406. 406 divided by 58 is 7.
Answer:
$18.24 (C)
Step-by-step explanation:
15.20 x 0.20 = 3.04
3.04 + 15.20 = 18.24

(B) - Yes, because the amount owed changes by 2.25 every time the miles change by 1.
Starting at 1 mile the price is 2.5 dollars.
Mile 2 is 4.75 dollars. What is the difference between 4.75 and 2.5? 2.25
Mile 3 is 7 dollars. What is the difference between 7 and 4.75? 2.25
Mile 4 is 9.25 dollars. What is the difference between 9.25 and 7? 2.25
Mule 5 is 11.5 dollars. What is the difference between 11.5 and 9.25? 2.25
The change is always 2.25 dollars.
The change is 2.25 dollars per mile.
One way to solve for this is (11.5 - 2.5)/(5-1)=2.25
This is (y2-y1)/(x2-x1). By picking 2 points, (x1,y1) and (x2,y2) you can solve for the slope (rate of change) between them.
