The initial payment per month being 30 and each movie being 2.50 means that if the total payment is 45 then you pay for 6 movies per month, 30x+6(2.5x)
Answer:
Directly proportional: as one amount increases, another amount increases at the same rate.
Inversely Proportional: when one value decreases at the same rate that the other increases.

Answer:
![(-9,16]](https://tex.z-dn.net/?f=%28-9%2C16%5D)
Step-by-step explanation:
we know that
The domain of x is equal to the interval--------> ![(-2,3]](https://tex.z-dn.net/?f=%28-2%2C3%5D)
All real numbers greater than 
and less than or equal to 
Let
For 
For 
so
The range of the function is the interval-------->
Answer:
A. -10
B. -1
C. 5
Step-by-step explanation:
A. 3x-4 = 3(-2)-4 = -10
B. 3x-4 = 3(1)-4 = -1
C. 3x-4 = 3(3)-4 = 5
Step-by-step explanation:
a) 3x + 5y = 8
4x - 3y = 1
• using the elimination method:
3x + 5y = 8 (×4)
4x -3y = 1 (×3)
12x + 20y = 32
12x -9y = 3
subract 12x from both equation:
20y - - 9y= 32 -3
20y +9y = 29
29y= 29
y= 29/29
y= 1
- substituting y= 1 in :
4x - 3y= 1
4x - 3(1) = 1
4x -3 = 1
4x = 1 + 3
x = 4/4
x= 1
b) 6p+ 4q = 20
5p - 2q = 6
• using the elimination method:
6p + 4q = 20
5p - 2q = 6 (×2)
6p + 4q = 20
10p - 4q = 12
add 4q + -4q to eliminate q.
6p+ 10p = 20+12
16p = 32
p = 32/ 16
p = 2
- subtituting p = 2 in :
5p - 2q = 6
5(2) -2q =6
10 -2q = 6
-2q = 6 - 10
q = -4 / -2
q = 2
