Answer:
The coordinates of point C are (8,8.5)
Step-by-step explanation:
The picture of the question in the attached figure
Let
----> coordinates of point C
we have that
The horizontal distance AB is equal to

The vertical distance AB is equal to

Find the horizontal coordinate of point C
we know that

so

----> equation A
----> equation B
substitute equation A in equation B



so
The x-coordinate of point C is equal to the x-coordinate of point A plus the horizontal distance between the point A and point C

Find the vertical coordinate of point C
we know that

so

----> equation A
----> equation B
substitute equation A in equation B



so
The y-coordinate of point C is equal to the y-coordinate of point A plus the vertical distance between the point A and point C

therefore
The coordinates of point C are (8,8.5)

Answer:
x=-5
Step-by-step explanation:
-3x+25=40. You want to isolate x so you have to subtract 25 from both sides. -3x=15. We then want x to be isolated so we have to divide both sides by -3 to make x by itself. x=-5. Therefore, x=-5.

Answer:
C. 200 minutes, $260
Step-by-step explanation:
The equations would look like this
Lynn = y = 1.10x + 40
Heather = y = 1.15x + 30
Now just plug in.
Lynn
260 = 1.10(200) + 40
260 = 220 + 40
260 = 260
Heather
260 = 1.15(200) + 30
260 = 230 + 30
260 = 260
