Answer:
X=6,x=-2
Step-by-step explanation:
To solve this question we will have to follow the step by step procedure
(x-6)(x+2)
x^2+2x-6x-12
Let's continue
x^2-4x-12
Let's factorise
x^2-6x+2x-12
x(x-6)+2(x-6)
(x-6)(x+2)
so to solve further that is to get the value for x
x-6=0
Add 6 to both sides
x=6
x+2=0
Substrate 2 from both sides
x=-2
Therefore x=6,x=-2
Answer:
465 Dollars
Step-by-step explanation:
15h+40f = Amount Charged
if: h = 7
f = 9
15(7)+40(9) = Amount Charged
105 + 360 = Amount Charged
465 = Amount Charged
He will charge 465 dollars.

Answer:
3
Step-by-step explanation:
subtract
Answer: X = y - yi - 7i
Y = (x + 7i)/(1 - i)
Step-by-step explanation: for the case of (X) you only need to pass the 7i to the other side with the subtraction sign (-7i), then we get this equation:
x + 7i = y − yi
X = y - yi - 7i
in the case of the (Y), first we select the common multiple.
y - yi = y(1 - i)
if we replace it in the original expression, we get the following equation:
x + 7i = y(1 - i)
after that you can pass the value (1 - i) to the other side dividing,
Y = (x + 7i)/(1 - i)
