Answer:
If you consume less energy you pay less with respect to the amount of energy you saved. If you saved 16% of total energy you should expect to lower your bill by 16%. Count how much is left -> 1900-1900*0.16=1596$
Answer:
(4,4)
Step-by-step explanation:
y = 2x - 4 -------eqn 1
4y = x + 12 ------eqn 2
From eqn 1 y = 2x - 4; insert in eqn 2
4 (2x-4) = x + 12 (open the bracket)
8x - 16 = x + 12 (taking like figures to the same side, sign changes)
8x - x = 12 + 16
7x = 28
x = 28/7
x = 4
From eqn 1
y = 2x - 4
y = 2(4) - 4
y = 8 - 4
y = 4
(x,y) = (4,4)
I’m pretty sure it’s 60 because if you look at angle 1 is next to the angle that measures 120 degrees and 60+120= 180
The answer is A) P’(5,4)Q’(2,7)
hope this helped .
They must equal 180°. Supplementary angles equal 180°
