What you must do for this problem is to re-imagine the equation in "vertex form"
Vertex form:
where "h" shifts the graph to the right if "h" is positive" and to the left if "h" is negative. K shifts the graph up and down.
a=1
h=1
k=0
So, your final answer should be:
Answer:
y=0
Step-by-step explanation:
R=3x+9y
(given)
21=3(7)+9y
21=21+9y
9y=21-21
9y=0
y=0
so their product is 112, so tis just a matter of doing some quick prime factoring and combining the factors about.
Reflect triangle ABC across the (y) axis, then transfer (x-7). Then ABC will be at ABC.2
