Answer:
C
Step-by-step explanation:
<span>9 hamburgers and 3 fries for 24.75 and 6 hamburgers and 4 fries for 19.50 can be represented by
9h + 3f = 24.75 and
6h + 4f = 19.5
Multiply by 4 36h + 12f = 99
and multiply by -3 -18h -12f = -58.5
12f and -12f cancel each other out
36h - 18h = 99 -58.5
18h = 40.5
h = 2.25
hamburgers cost 2.25
9h + 3f = 24.75
9(2.25) + 3f = 24.75
3f = 24.75 - 20.25 = 4.50
f = 150
fries cost 1.50
One hamburger and one fries can be represented by :
h + f
2.25 + 150 = 3.75</span>
Answer:
Yes, they are similar. The answer you would click is Yes, the corresponding sides are proportional.
Step-by-step explanation:
The second figure is a dilation of the first, making them similar. The dilation is by a factor of 2 and a half.
the equation of the line is
y = -3x + 6
slope is m = -3
as we know that for parallel lines, the slope is always equal.
so the slope of the new line is also m = -3
it is also passing through (-4,9)
so the equation of the line i s
m= -3
so the answer is y = -3x - 3
