Answer:
72
Step-by-step explanation:
The
slope is the change in y divided by the change in x.
The
slope is the ratio of rise to run.
The
slope is the rate of change of the function at a certain point.
The
slope is the first derivative of a function.
Accordingly, the slope of this line <span>d=420-65t is the coefficient of variable "t" if we consider that d for the dependent variable and t for the independent
Therefore
slope =
- 65</span>

Answer:
a = 22
b = 7
Step-by-step explanation:
Let the two numbers be represented as a and b.
a + b = 29
a - b = 15
Using elimination method
Add both equations
2a = 44
Divide both sides by 2 to get a
2a/2 = 44/2
a = 22
Now substitute a = 22 in any of the equations to get b .
Using the first equation, we have
a + b = 29
22 + b = 29
Subtract 22 from both sides of the equation
22 - 22 + b = 29 - 22
b = 7
Therefore the two numbers are 22 and 7
