Answer:</h2>
By Substitution Method
<h2>
Step-by-step explanation:</h2>
Solve by Substitution :
We have two equations
y = 5x ---------------> Equation 1
y = 2x - 15 ------------> Equation 2
y= 2x - 15 and y= 5x
So Put the value of y in Equ 2
(5x) - 2x = -15
3x = -15
Solve equation [1] for the variable x
3x = - 15
x = - 5
Now
y = 5x
x = -5
Use the x value to solve for y
y = 5(-5) = -25
Solution :
{y,x} = {-25,-5}
So y= -25 and x= -5
-32
Step-by-step explanation:
Step 1:
The rate of change over an interval is got by finding the change in g(x), the change in x and dividing it.
Step 2:
Given, x denotes the number of miles walked by Marcus for the fund raiser
g(x) denotes the amount of money he has left to raise after x miles of walking
g(x) for the interval [6,10] is 408,280
Change in x = 10-6 = 4
Change in g(x) = 280-408 = - 128
Rate of change = -128/4 = -32
Hence the average change in rate over the given interval is -32
