Y = 3x - 4
y = 3(-1) - 4
y = -3 - 4 = -7
Graph pair is (-1, -7)
y = 3(0) - 4
y = 0 - 4 = -4
Graph pair is (0, -4)
y = 3(2) - 4
y = 6 - 4 = 2
Graph pair is (2, 2)
y = 3(4) - 4
y = 12 - 4 = 8
Graph pair is (4, 8)
Answer:
(- 3, 4)
Step-by-step explanation:
given the 2 equations
2x - y = - 10 → (1)
y = 4 → (2)
Substitute y = 4 into (1) and solve for x
2x - 4 = - 10 ( add 4 to both sides )
2x = - 6 ( divide both sides by 2 )
x = - 3
solution is (- 3, 4 )
Answer:
16
Step-by-step explanation:
x+2x=24
x=8
2x=raisins=16
