Answer:
(2/3, 13/3) (Exactly one solution)
Step-by-step explanation:
Write these equations in a column:
x+y=5
2x-y=-3
Note that we can eliminate y immediately by adding these two equations together. We get:
3x = 2, so that x = 2/3.
Substituting 2/3 for x in the first equation, we get:
2/3 + y = 5. Clear out fractions by multiplying all three terms by 3:
2 + 3y = 15, or 3y = 13. Then y = 13/3, and the solution is
(2/3, 13/3) There is exactly one solution.
B. If square-foot is on the x-axis then we can substitute for x in the equation and solve, and when we do, we get 2473.302 which is is B when rounded.
Answer:
d
Step-by-step explanation:
Standard form is x + y = number
y + 4 = -6(x + 6)
y + 4 = -6x + -36
y = -6x - 40
6x + y = -40
Answer:
x = 46 degree
Step-by-step explanation:
x + x + 88 = 180
2x + 88 = 180
2x = 180 - 88
2x = 92
x = 92/2
x = 46
