Answer:
(2, 1 )
Step-by-step explanation:
Given the 2 equations
y = 6x - 11 → (1)
- 2x - 3y = - 7 → (2)
Substitute y = 6x - 11 into (2)
- 2x - 3(6x - 11) = - 7 ← distribute and simplify left side
- 2x - 18x + 33 = - 7
- 20x + 33 = - 7 ( subtract 33 from both sides )
- 20x = - 40 ( divide both sides by - 20 )
x = 2
Substitute x = 2 into (1) for corresponding value of y
y = 6(2) - 11 = 12 - 11 = 1
Solution is (2, 1 )
Answer:
-15
Step-by-step explanation:
3550 cds divided by 15 cds/ rack = 236.66667
Meaning that there will be 236 full racks and the last rack will only have 10 cds
Answer:
D. y = 4x
Step-by-step explanation:
y = 4x
Plug in The point (-1,-4) into the equation
when x = -1, y = 4(-1) = -4
So (-1,-4) is the solution of y = 4x
