Answer:
y=-9x-17
Step-by-step explanation:
27x+3y=50
3y=-27x+50
y=-9x+50/3
m=-9
y+11=-9(x+2/3)
y+11=-9x-6
y=-9x-17
Square both sides
9(x + 2) = x + 4
Expand
9x + 18 = x + 4
Subtract x from both sides
9x + 18 - x = 4
Simplify 9x + 18 - x to 8x + 18
8x + 18 = 4
Subtract 18 from both sides
8x = 4 - 18
Simplify 4 - 18 to -14
8x = -14
Divide both sides by 8
x = -14/8
Simplify 14/8 to 7/4
<u>C. x = -7/4</u>

Answer:
To find how tall he was at the end of the school year, you add his height at the beginning of the year and during the school year. First you should just add the inches.
2 1/4 + 7/8
The common denominator is 8.
2 2/8 + 7/8
2 9/8
3 1/8
Put back in the 5 ft.
So, Jerry was 5ft and 3 1/8 inches at the end of the school year.
Hope this helped! :)
