Using complete sentences, explain how to find the average rate of change for f(x) from x = 4 to x = 7.

1 answer:

4 0

Really you just need to plug in each one. So 4 plugged into x in the equation comes out to be 87. And if you plug in 7 it comes out to be 93. so if you take 93 subtract 87 from it, it comes to be 6. and if you take 7 and subtract 4 from it you get 3. So when we plug it in it doubles. So the average rate of change(slope) is 2. because 6/3=2. Average rate of change is the exact same thing as slope.

Answer:

Step-by-step explanation:

We can graph the line using the y and x-intercepts. To find the y-intercept, we substitute x = 0 into y = -2x - 2 so the y-intercept is (0, -2). To find the x-intercept, we substitute y = 0 into y = -2x - 2 so the x-intercept is (-1, 0). The line that goes through both of these points is line B.

The perimeter of a rectangle is 37. The length is 1 less than 12 times the width. What is the length and width of the rectangle

iren [92.7K]

Width = W
Length = 12W - 1
Perimeter = 2L + 2W = 37

In the perimeter equation substitute the length equation in for L to get the equation in terms of W
2L + 2W = 37
2(12W - 1) + 2w = 37

Distribute
2(12W - 1) + 2w = 37
24W - 2 + 2w = 37
26W = 39
W = 3/2 = 1.5
Width = 1.5

Lastly, solve for length
L = 12W - 1
L = (12 • 1.5) - 1
L = 18 - 1
L = 17
Length = 17

If the purchase price for a house is $218,500, what is the monthly payment if you put 3.5% down for a 30 year loan with a fixed

artcher [175]

218,500 - (3.5% down payment) =
210,852.50
30 years = 360 months
rate 6.5%
Use the loan payment formula (REALLY complex - see attached).
rate = 6.5/1,200 = 0.005416667 

monthly payment = (rate + [rate / (((1 + rate)^months) -1)] * principal
monthly payment = (0.005416667 + [0.005416667 / (((1.005416667)^360)-1)] * principal
monthly payment = (0.005416667 + [0.005416667 / (((1.005416667)^360)-1)] * principal
monthly payment = 0.005416667 + [(0.005416667 / 6.9917988084 -1)] * 210,852.50 
monthly payment = 0.005416667 + [(0.005416667 / 5.9917988084)] * 210,852.50 
monthly payment = 0.005416667 + [(0.005416667 / 5.9917988084)] * 210,852.50 
monthly payment = (0.005416667 + 0.0009040135) * 210,852.50
monthly payment = 0.0063206805 * 210,852.50
monthly payment = 1,332.73
