Answer:
-3
Step-by-step explanation:
y=1/2x-3
y=mx+b where m=slope and b=y-intercept
b=-3
Answer:
(0, -3)
explanation:
- original coordinates of C: (0, -7)
If reflected over y axis, there will be additive inverse in x unit
use the formula: (x,y) → (−x, y)
Then if translated vertically, there will be change in y axis:
(0, -7+4) → (0, -3)
The simplified expression is c^5
In both problems, the sum of side lengths is the perimeter. Opposite sides of a parallelogram (or rectangle) are equal in length, so you can find the perimeter by doubling the sum of adjacent sides.
25. 2(x +(x +15)) = (x +45) +(x +40) +(x +25)
