Answer:
(6, -4) does not fit with these two equations
Step-by-step explanation:
y = 8 - 2x
x + 3y = 12
fit (6, -4) into the equations
-4 = 8 - 2(6)
8 - 2(6) = 8 - 12 = -4
works for this one
6 + 3(-4) = 12
6 + 3(-4) = 6 - 12 = -6
doesnt work for this one
Answer:
The last 2.
Step-by-step explanation:
Answer: B
Step-by-step explanation:
4(x+3)+2x=6(x+2)
4x+12+2x=6x+12
6x+12=6x+12
12=12
All real solutions
5+2(3+2x)=x+3(x+1)
5+6+4x=x+3x+3
11+4x=4x+3
11=3
No solution
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
