Step 1: Subtract 3x from both sides.
−x+7=−52
Step 2: Subtract 7 from both sides.<span><span><span><span>

There are many. For example, 32 x 0.5 is 16. You can multiply 4 x 4 to get 16, so it is rational.
Answer:
student A- can run 2/3 mile in six minutes
1/9 mile/min
student B- can run 1/2 mile in 4 minutes
Speed=1/8 mile/min
student C- can run 4/5 mile in 8 minutes
speed=1/10 mile/min
Step-by-step explanation:
Answer:
m<v' is 133 m<x' is 102 m<y' is 136
Step-by-step explanation:
when reflecting the shape doesn't change shape or size so the angle measure will stay the same
Answer:
y = - x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 2, 2) and (x₂, y₂ ) = (2, - 2) ← 2 points on the line
m = 
= 
= - 1 , thus
y = - x ← equation of line
