Answer:
To make the equation complete square , we have to add 11 .
Step-by-step explanation:
Given as :
The linear equation is
x² + 4 x - 5 = 2
Now, move the constant to left side of equation
So, x² + 4 x - 5 - 2 = 0
Or, x² + 4 x - 7 = 0
<u>Now, to make equation complete square , let add 11 both side</u>
So, x² + 4 x - 7 + 11 = 11
Or, x² + 4 x + 4 = 11
Now, applying mid-term break
So, x² + 2 x + 2 x + 4 = 11
Or, x ( x + 2) + 2 (x + 2) = 11
Or, (x + 2) ( x + 2) = 11
Or, (x + 2)² = 11
Hence, To make the equation complete square , we have to add 11 . Answer
First, you have to distribute the -1 throughout the parentheses, which gives you 7x-3x-10=-46.
Then, you combine 7x and -3x, which gives you 4x-10=-46.
Then, you add 10 to both sides of the equation, which gives you 4x=-36.
FInally, you divide both sides of the equation by 4, which gives you x=-9.
Answer:
x = 2 and y = -2
Step-by-step explanation:
We must first eliminate the y-variable:
2x + 3y = -2
3x - 6y = 18
4x + 6y = -4
3x - 6y = 18
_________
7x = 14
x = 2
Since we know x=2, we plug that back into one of the original equations to find y:
2x + 3y = -2
2(2) + 3y = -2
4 + 3y = -2
3y = -6
y = -2
Therefore, x = 2 and y = -2
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
75 (7) = 525
<span>72 + 79 +74 + 76 + 76 + 75 = </span>452
525 -452 = 73
answer
