Answer:
A- 12 percent
Step-by-step explanation:
You can see on the graph that the charged percentage of capacity changes from 40 to 50 in 5 minutes. Then the increase in 6 minutes will be slightly more than 10 percent.
The linear rate is (10%)/(5 min) = 2%/min, so in 6 minutes it will be
(2%/min)×(6 min) = 12%
This calculation is consistent with our observation from the graph.
Every 6 minutes, 12 percent is added to the capacity.
Answer:
x = -3
Step-by-step explanation:
y = -x + 2
7x + 4y = -1
Subsitution method: (Substitute y)
7x + 4(-x+2) = -1
Expand.
7x + (-4x + 8) = -1
One plus and one minus make one minus. Two plus makes a plus.
7x -4x + 8 = -1
Simplify.
3x + 8 = -1
Isolate 3x.
3x = -1-8
= -9
Find x.
x = -9 ÷ 3
= -3
We have been given an equation 
that represents umber of walls, w, that Joe can paint in t hours. We are asked to find the number of hours it will take Joe yo paint 7 walls.
To solve our given problem, we will substitute 
in our given equation as:
Let us solve for t.
Therefore, it will take 
hours Joe to paint 7 walls.
Answer:
- Any of x = {-3, 5, -1, 0}
Step-by-step explanation:
Since the relationship in the table is not a function, Rae could put any values for x that is already in the table.
This will result in repeat of x-values with different corresponding y-values.
