The given options are:
- (A)x+y = 20
- (B)7 apps and 14 movies
- (C)x-y= 20
- (D)y=-x+ 20
- (E)8 apps and 12 movies
- (F)xy= 20
Answer:
- (A)x+y = 20
- (D)y=-x+ 20
- (E)8 apps and 12 movies
Step-by-step explanation:
If Elizabeth has a combined total of 20 apps and movies.
Where:
Number of apps=x
Number of Movies =y
Then:
Their total,
If we subtract x from both sides
x+y-x=-x+20
In Option E
8 apps and 12 movies add up to 20. Therefore, this could also apply.

3. 2x^2 - 5x -7
4. (2x + 1)(x - 5)
Step-by-step explanation:
Step-by-step explanation:
2x-y=6 --------(1)
x+y=6 -------(2)
_____ Adding (1) and (2)
3x = 12
x=4
Substitute x on equation (2)
4+y=6
y=2
Answer:
