Answer:
By using completing the square method, equation (x - 12) (x + 4) = 9 can be solved as x = (4 + √ 73) or (4 - √ 73)
I line that is perpendicular is a line with reversed slopes like 2/1 is perpendicular to -1/2. So find the slope by getting the y by itself and reverse it. Remember to switch the signs too! P.S. if you don't know how to get the y by itself just take and subtract 3x from -5y and -4 then divide by 5. Hope I helped!
Answer:
The total money in account after 8 months is $72 + $8 x
Step-by-step explanation:
Given as :
Total money available in saving account = $72
The money saves each month in account = $x
So, The money saves in account after 8 months = $x × 8 = $8 x
Let The total money in account after 8 months = $A
Or, A = money available in saving account + money saves in account after 8 months
i.e A = $72 + $8 x
So, The total money in account after 8 months = A =$72 + $8 x
Hence, The total money in account after 8 months is $72 + $8 x Answer
