To find this you need to divide 7.50 by 3. You then get $2.5, which is the unit rate for one apple.
At x=-4,, that is where y=0 and y has to be positive
that is where the slope of graph changes, because that is the vertex
so basically we flip the graph at x=-4
it is positive for x>-4
fliped for x<-4
so basically graph
y=x+4 in x<-4
y=-x-4 in x<-4
1. <u><em>a=-1+b/7 is the right answer.</em></u> First you had to add by b from both sides of equation, and it gave us,
. And then simplify, and it gave us,
. Divide by 7 from both sides of equation, and it gave us,
. Finally simplify, and it gave us the answer is a=-1+b/7 is the right answer.

2. <em><u>a=-b-1/2 is the right answer.</u></em> First you had to add by 2b from both sides of equation, and it gave us,
. And then simplify, and it gave us,
. Next you can also divide by -4 from both sides of equation, and it gave us,
. Finally simplify, and it gave us the answer is a=-b-1/2 is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

X equals 62 because you take 147 and subtract it from 180 and that gives you 33.
then you add 33 and 85 together to give you 118. Then you subtract 118 from 180 and that gives you 62.
x=62
