B. Between 5 and 10 years old
Answer:
first one
Step-by-step explanation:
Tracey bought 10 movies
some cost 13 and the others 16
Let x be the movies that cost 13 and y ones that cost 16
we can state that
since Tracey both ten
since the total price is 139
so the system is :

Answer:
you have to use multiplication maybe division and addition
Step-by-step explanation:
Answer:
Assuming the other side is 30, x=12
Step-by-step explanation:
X+(X+6)=30
2x+6=30 (open the brackets by distributing the plus sign inside)
2x=24 (subtract 6 from both sides)
x=12 divide both sides by 12
This makes sense because of x is 6, and x+6 is 18, 6+18=30.
Answer:
First Graph:
Slope = - 4/5
Point-Slope Form: y - 3 = - 4/5 (x + 2)
Point: (-2, 3)
Second graph:
Slope = 4
Point-Slope Form: y + 6 = 4 (x + 1)
Point: (-1, -6)
Step-by-step explanation:
First graph has two points: (-2, 3) & (8, -5)
Use the two points to find the slope using the Slope-Formula
Slope-Formula: y2 - y1/x2 - x1
m = slope
m = - 5 - 3/8 - - 2
m = - 8/10
m = - 4/5
The slope of the line will be - 4/5
Now for Point-Slope Form, we’ll need to use the two points with the slope to identify the Point-Slope Form of the graph
Two points: (-2, 3) & (8, -5)
Slope: - 4/5
Point-Slope Formula: y - y1 = m (x - x1)
Point-Slope Form: y - 3 = - 4/5 (x + 2)
The point will be: (-2, 3)
