So you divide by 2 because there is 2 buildings. You get 760. Now, just take 200 away from one building, and 200 away from the other, and you get 560 for Building A, and 960 from Building B.
Answer: 11
Step-by-step explanation: write the equation.
2(x+4)=30
Divide by 2
x+4=15
Subtract 4
x=11
The answer is D because you open the parabola downward and you go down instead of to the left.
Answer:
F y=12
Step-by-step explanation:
cant be an 'x=' line because that would parallel not perpedicular to y axis
given y coordinate is 12 so y=12
Answer:
a = 23
b = 10
Step-by-step explanation:
The general formula is
y = 3x + 5
Just to check, let x = 2
y = 3*2 + 5
y = 6 + 5
y = 11
And a confirmation check
x = 3
y = 3*3 + 5
y = 9 + 5
y = 14
So for a
x = 6
y = 6*3 + 5
y = 18 + 5
y = 23
For b, you know y
35 = 3x + 5
<u>- 5 -5 </u> Subtract
30 = 3x Divide by 3
30/3 = 3x/3
x = 10
