6x + 11 - 16x = -21
6x-16x = -32
-10x = -32
x = -32/-10
x = 3.2
Answer:
So, we purchased 9 songs and 4 games for 20.1$.
So, we purchased 10 songs and 6 games for 25.5$.
So, we purchased 10 songs and 10 games for 33.9$.
Step-by-step explanation:
We have receive a $35 gift certificate from an online retailer that sells digital music and games. Each song costs $1.29 and each game costs $2.10.
First case:
So, we purchased 9 songs and 4 games for 20.1$. We have 13 items for 20.1$.
Second case:
So, we purchased 10 songs and 6 games for 25.5$. We have 16 items for 25.5$.
Third case:
So, we purchased 10 songs and 10 games for 33.9$. We have 20 items for 33.9$.
Answer:
A) increasing x > -1 ; decreasing x <-1
Step-by-step explanation:
We use the given graph to find the intervals where the function is increasing , decreasing and constant
We analyze the graph from the left
From the left the graph starts decreasing and it is decreasing till -1
From the point (-1,0) the graph changes direction and starts increasing
So we can say that the function is decreasing from -infinity to -1
and increasing from -1 to infinity
decreasing from -infinity to -1 means decreasing x <-1
increasing from -1 to infinity means increasing x > -1

Answer:
x=-7/2, y=1
Step-by-step explanation:
y=-2x-6
y=x+9
I'm going to use elimination.
2y=2x+9
y=-2x-6
3y=3
y=1
Enter y into one of the equations to find x.
2=2x+9
2x=-9+2
2x=-7
x=-7/2
