Answer:
A.
Step-by-step explanation:
The negative gives a reflection in the x-axis.
The 2 is a vertical stretch factor 2.
2x-3=0
because once you subtract 4.5 from both sides to get 0 on one side then you get 2x-3=0
The answer is 4x²-48x + y²= -140
Answer:
x = 6
y= 24
Step-by-step explanation:
90+ (3y+18) = 180. reason [being co-interior angle
(15x+30)+10x = 180. reason [being co-interior angle
Answer:
8
Step-by-step explanation:
7x/4 -3x/8=11
lets simplify the left hand side 7x/4 -3x/8
first the lcm which is 8
(2)7x-3x/8 = 14x-3x/8 = 11x/8
11x/8 = 11
cross multiply
11x = 8 x 11
divide both sides by 11
x = (8x11)/11 = 8
