Answer:
y=-10/7x+4
Step-by-step explanation:
10x+7y=28
-10x -10x
7y=-10x+28
7/7y=-10x/7+28/7
y=-10/7x+4
Answer:

Answer:
C(8,14)
Step-by-step explanation:
initial point (-3,-5) and terminal point (5,9)
vector form=(change in x, change in y)
V=(Xf-Xi,Yf-Yi)
V=[5-(-3), 9-(-5)]
V=(8,14)

Answer: 37</h3>
====================================================
Work Shown:
T = tens digit of the original number
U = units digit of the original number
U+T = 10 since the digits add to 10. Solve for U to get U = 10-T
10T+U = original number
10U+T = new number where digits are reversed
-----------
new number = (old number) + 36
10U+T = (10T+U)+36
10U+T = 10T+U+36
10(10-T)+T = 10T+10-T+36 ... plug in U = 10-T
100-10T+T = 10T+10-T+36
-9T+100 = 9T+46
100-46 = 9T+9T
54 = 18T
18T = 54
T = 54/18
T = 3 is the tens digit of the original number
U = 10-T
U = 10-3
U = 7 is the units digit of the original number
10T+U = 10*3+7 = 30+7 = 37 is the original number
73 is the reversed number.
73-37 = 36 is the difference, showing that 37 increased by 36 leads to 73. The answer is confirmed.
