Y = 3x - 1 ---- (1)
x - y = -9 ---- (2)
From Equation 2:
x - y = - 9
x + 9 = y
y = x + 9 --- (2a)
(1) - (2a):
0 = 3x - x - 1 - 9
0 = 2x - 10
2x - 10 = 0
2x = 10
x = 5 ---- sub into (1)
y = 3(5) - 1
y = 15 - 1
y = 14
I believe tye answer is C
Answer:
y = 4x+ 3
Step-by-step explanation:
Answer:
15 ft
Step-by-step explanation:
If every 1/4 of an inch is a foot, than every inch is 4 feet.
1 inch = 4ft
3 inches = 12ft
1/4 + 1/4 + 1/4 = 3/4
3/4=3 ft
12+3=15ft
