1. added four to both sides
2. divided both sides by two
7.5 i believe. not very good at math tho lol
The point with a coordinate of (2,5) will be translated into y=-x line. The transformation for y=-x would be:
1. x'= -y
2. y'= -x
For x=2 and y=5 would be:
x'= -y
x'= -5
y'= -x
y'= -2
The translated coordinate would be: (-5, -2)
13. Your answer is 18,000 - 7,500
14. 72 (B)
15. $3.15 (C)
16. 1 1/8 pounds (C)
Answer:
Step-by-step explanation:
Parallel equations have same slope
Therefore slope of 3x + y = -2 is same as slope of other equation.
Slope of 3x + y = -2 is
m=-3
Now we have write equation having slope -3 and passing through point (5, -5)
