Answer:
<u>$25</u>
Step-by-step explanation:
10*2=20
20+5=25
Answer:
Step-by-step explanation:
a.
2y - 3x = 5
2(-2) - 3x = 5
-4 - 3x = 5
-3x = 9
x = -3
(-3,-2) is another solution
b.
(-1,1)
2y - 3x = 5
2(1) - 3(-1) = 5
2 + 3 = 5
5 = 5
true, the point is a solution to the equation because the equation is true after substituting x and y with the point (-1,1)
(4,1)
2y - 3x = 5
2(1) - 3(4) = 5
2 - 12 = 5
-10 = 5
not true, the point is not a solution to the equation because the equation is not true after substituting x and y with the point (4,1)
c. You can use the points from the given (-1,1) and (-3,-2) to form a line. You then shade whichever half solves the solution using points on the graph.
Answer: 
and 
Step-by-step explanation:
Observe the number line attached.
In order to find which numbers are a distance of 
from 
on a number line, you can follow these steps:
First step: You must locate the number on the number line.
Second step: Move to the left. Notice that the distance between the numbers and is
Third step: Move to the right. Observe that the distance between the numbers and is
You can also verify this through the following addition and subtraction:
Therefore, the numbers that are a distance of from on a number line, are:
and
