Answer:
e
Step-by-step explanation:
let x be the number of one- bedroom and y the number of two - bedroom apartments , then create 2 equations and solve simultaneously.
x + y = 12 ( subtract y from both sides )
x = 12 - y → (1)
360x + 450y = 4950 → (2)
substitute x = 12 - y into (2)
360(12 - y) + 450y = 4950 ← distribute parenthesis and simplify left side
4320 - 360y + 450y = 4950
4320 + 90y = 4950 ( subtract 4320 from both sides )
90y = 630 ( divide both sides by 90 )
y = 7
there are 7 two- bedroom apartments
Answer:
4(x-9)² - 17
Step-by-step explanation:
if moving left or right, the a value for (x-a) + b changes, and if it move up or down, the b value for (x-a) + b changes
So you times the -2 with the bits inside the bracket so:
-2 x t= -2t
-2 x 4 2/3 = -9 1/3
So then that makes:
-2t - 9 1/3= 9 1/2
So to get what t equals you have to get it by itself so you add the -9 1/3 to both sides of the equation to get:
-2t=18 5/6
So then you divide by -2 on both sides to get
t=-9 5/12
Which is the answer. :-D
