Answer: No. both are independent quantity. Therefore, the number of books purchased does not affect the value of m.
Step-by-step explanation:
Given: Julio and his sister bought 8 books and m magazines for $1 each.
The amount of money that Julio spent is represented by the expression 1/2(m+8)

Step-by-step explanation:
2x-3y=-10
y=4x
Since the y is already isolated, you can use substitution to find the answer to this equation. Simply replace any y values in the first equation with 4x:
2x-3(4x)=-10
2x-12x=-10
-10x=-10
x=1
y=4(1)=4

Answer:
Step-by-step explanation:
(2x + 3) (-x - 2)
distribute first term, to the second term:
2x(-x) + 2x(-2) + 3(-x) + 3(-2)
multiply:
+ (-4x) + (-3x) + (-6)
combine the like terms:
- 4x - 3x - 6
-7x
- 7x - 6
final answer :
- 7x - 6
hope this helped !!
