Answer:
1 job / 2 hours + 1 job / 3 hours = 1 job / time it takes for both when working together
time it takes for both when working together = 1.2 hours
Step-by-step explanation:
You can't use 1 point on a line to make a full slope. To make a full slope you would need 2 points on a line. To make more than one slope you would need more than 2 points on a line.
Hope this helped! :D
Answer:
Sketch the following three graphs:
1) y = (x + 3)²
2) y = -(x + 3)²
3) y = x + 3
First two are parabolas with vertex at (-3,0)
Third one is a line which intersects both the parabolas as (-3,0)
4/5 x = 64
multiply both sides by 5/4
5/4 *4/5 x = 5/4 * 64
x = 80
Given:
The algebra tiles of an equation.
To find:
The equation represented by the given model.
Solution:
On the left side of the model we have 4 tiles of (-x) and 3 tiles of (-1). So,
On the right side of the model we have 8 tiles of (-1). So,
Now, equate the LHS and RHS to get the equation.
Therefore, the equation for the given model is .
