A = 1/2 h (a+b)
A / 1/2 h = a + b
A / 1/2 h - b = a
a = A / 1/2 h - b
Hope this helps
Answer:
x = -7
Step-by-step explanation:
The vertical line through (-7, -5) will be of the form ...
x = constant
To make the line go through the given point, the constant must be the x-coordinate of that point:
x= -7
-9x^2-15x. Each one is divided by -7xy
Answer:
The house is increasing in value by 2% each year.
Correct the increase is 1.02 per year the value of b>0 and the percentage of increase each year is:
Step-by-step explanation:
For this case if we have this expression

We have the same functional forma like the exponential model given by:

Where a = 210000 represent the constant or initial value and b = 1.02 represent the base.
So let's analyze the possible options:
The house has a starting value of 1.02.
False the starting value for this case is 210000 since if x=0 then we see that the value is 210000
The house is decreasing in value by 2% each year.
False the increase is 1.02 each year so then in % we have

We have an increase of 2% each year
The house is increasing in value by 2% each year.
Correct the increase is 1.02 per year the value of b>0 and the percentage of increase each year is:
The value of the house is changing by 0.02% each year.
False the increase is 2% per year
Answer:
x =8
The angles are
3x= 24
7x+4 = 60
13x-8 =96
Step-by-step explanation:
The sum of the angles of the triangle is 180
3x+ 7x+4 + 13x-8 =180
Combine like terms
23x -4 = 180
Add 4 to each side
23x -4+4 =180+4
23x =184
Divide by 23
23x/23 = 184/23
x =8
The angles are
3x= 3*8 =24
7x+4 = 7*8+4 = 56+4 = 60
13x-8 = 13*8-8 =104-8=96
