Answer is D
(1.5,3)
Explanation:
Substitute
1) 3-2(1.5)=0
So 0=0
2) 3=8(1.5)-9
So 3=3
For #3, it's 5.4 because you divide the total amount of money made by the amount of money earned per hour.
49.95/9.25=5.4 hours
The answer is 45.9 you Add it
Equate real part and imaginary part:
LHS:
real part -- 12
imaginary part -- 5y
RHS:
real part = 4x
imaginary part = 25
Equating::
12 = 4x
x = 12/4
x = 3
Again:
5y = 25
y = 25/5
y = 5
So,
x = 3
y = 5
