We can solve by using the substitution method
y=-5/3x+3
y=1/3x-3
They are equal to each other because they are both equal to y
-5/3x+3=1/3x-3
Subtract both sides by 1/3 and subtract 3 from both sides
-5/3x-1/3x=-3-3
-2x=-6
Divide both sides by -2
x=3
Plug in x into one of the equation to solve for y
y=1/3(3)-3
y=1-3
y=-2
(3,-2)
41.25 because you divide the cost into the profit and that equals 41.25
Answer:
27 inches
Step-by-step explanation:
We can use a ratio to solve
10 15
---- = ----
18 x
Using cross products
10x = 15*18
10x=270
Divide each side by 10
10x/10 = 270/10
x = 27
Answer:
(7, - 2 )
Step-by-step explanation:
a translation of 2 units right means add 2 to the x- coordinate
a translation of 3 units up means add 3 to the y- coordinate
(5, - 5 ) → (5 + 2, - 5 + 3 ) → (7, - 2 )
