(intro) Slope is change in y divided by change in x (axes). Here, the y axis is depth and the x axis is hours. So, the slope is change in depth between any two points, divided by the change in hours between the same points. The slope of this line is half a foot depth divided by 2 hours.
a) So, the slope is 0.5 / 2 = 0.25, or 1/4.
b) The graph shows a constant rate of change because the line is straight (it increases at the same speed. If the line was curving, it would not be a constant rate of change).
c) Yes, because the line has a constant rate of change now.
Answer:
Dori:3x+3y=11.25
Nemo:4x+2y=10
Step-by-step explanation:
Let x and y represent tacos and double Deckers respectively.
For three tacos and three double Deckers, Dori pays $11.25
Writing an equation the statement, we obtain
3x+3y=11.25
Also,for four tacos and two double Deckers, Nemo pays $10
This implies
4x+2y=10
The answer is c I hope that helps
Answer:
k= -8
Explaining:
Move variable to the left-hand side and change its sign.
2.25k - 6.5k - 20= 6.5k - 6.5k + 14
Since two opposites add up to zero, remove them from the expression.
2.25k - 6.5k - 20= 14
Collect like terms!
-4.25k = 14 + 20
Add the numbers
-4.25k = 35
Divide both sides of the equation by -4.25
So you will get the answer: k= -8
