What’s your question/what do you need help with?
Answer:
BRAINLY PLEASE
Step-by-step explanation:
y=-3x+2
This is a neat little question. I don't think I've seen it before.
Step one
=======
Find c
3^2 + 4^2 = c^2
9 + 16 = c^2
c^2 = 25
c = 5
Step 2
====
Set up your first equation for b^2
a^2 + 4^2 = b^2 from triangle XWY
Step 3
=====
Set up your second equation for b^2
25 +b^2 = (a + 3)^2 from triangle XWZ
Step 4
=====
Put the results of Step 2 into step 3 and solve
25 + a^2 + 16 = (a + 3)^2 Collect the like terms on the left.
41 + a^2 = (a + 3)^2 Expand the brackets on the right
41 + a^2 = a^2 + 6a + 9 Transfer the 9 to the left.
32 + a^2 = a^2 + 6a Subtract a^2 from both sides.
6a = 32 Divide by 6
a = 32 / 6
a = 5 2/6
a = 5 1/3
I’m not sure if this is the answer you are looking for because the question is confusing but I have done the maths.
For plan 1 you are able to watch 3 movies and pay the annual fee for a total of $52.50 . (Meaning you can only watch 3 movies a year) (annual means per year, so that means that every month it is $3.75 per month ($45 divided by 12) with additional costs of $2.50 per movie)
For plan 2 you are able to watch 14 movies a year with a total of $52.50.
The answer that only made sense to me is (0,0)
