As the second equation is equivalent if you divide the entire equation by 2
A) Let x = cost of t-shirt:
x= 22.95-12.25
B) x = 22.95 -12.25 = 10.70
C) the t-shirt cost $10.70
Answer: i think you're talking about dilations and there are specific formulas depending on the situation.
for example: the dilation of (x,y) is (-1/2x, -1/2y).
you'd probably need to subtract 2 from whatever measurements of the shape you're working with. i'm not completely sure though
No steps are wrong. To solve this equation, you need to isolate the y. So, you would add 4.6 to both sides to cancel out the 4.6 on the right side and isolate the y.
Answer:
A. -f(1/2 x)
Step-by-step explanation:
Reflextion about the x-axis is
f(x) -> -f(x)
and horizontal dilation is
f(x) -> f(-x/b) where b is the factor of dilation.
so the proper answwer is
A. -f(1/2 x)
