Movies = x
Video Games = y
1st Month = 5x+3y = 26 (1)
2nd Month = 7x+9y = 64 (2)
(1) x 3; 15x+9y = 78 (3)
(3)-(2);
15x+9y-(7x+9y) = 78-64
15x+9y-7x-9y = 14
8x = 14
x = $1.75
Therefore substituting x in (1);
5x1.75+3y = 26
8.75+3y = 26
3y = 26-8.75
y = $5.75
Hope i helped! Please mark Brainliest if you can :)
Answer:
A. (3x^2 + 1)(x + 3)
Step-by-step explanation:
3x3 + 9x2 + x + 3
I will factor by grouping
Factor out a 3x^2 from the first two terms
3x^2 (x+3) + (x+3)
Then factor out an x+3
(x+3)(3x^2+1)

C. is true because if A=F and B= G, AB=FG
D. is true because of what I said for A.
Hope this helps.
