Answer:
Step-by-step explanation:
The average rate of change is the slope. Slope has a formula that is the change in y over the change in x, which is a fraction. The only time a fraction can have a vlue of 0 is where the numerator of the fraction is equal to 0 (since we are not allowed to have a denominator of 0). If the change in y is in the top of the slope fraction, then we have to find the interval where the y values are the same. I'll show you one where the y values are not the same so you can compare it to the slope where the y values are the same. We will find the slope of choice A.
When x = -3, y = 0 so the coordinate is (-3, 0).
When x = 5, y = 5 so the coordinate is (5,4). Now let's find the slope (aka average rate of change) between those 2 coordinates:
and the top of the fraction is a 1, not a 0, so the average rate of change between these 2 points is 1/2, not 0. Now let's do D.
When x = -3, y = 0 so the coordinate is (-3, 0).
When x = -1, y = 0 so the coordinate is (-1, 0). The slope between these 2 points is
This fraction is equal to 0 because the numerator is 0. Choice D is the one you want.
Answer:
294 inches squred
Step-by-step explanation:
3 x 10 = 30
3 x 9 = 27
10 x 9 = 90
2(30) + 2(27) + 2(90) = 294
Answer:
thats the answer D

$70 for 5 hours = 70/5 for 1 hour.
70 / 5 = 14
That means $14 for 1 hour.
To find how much for 12 hours, multiply the price of 1 by 12 to get the price of 12 hours.
1 hour = $14
12 hours = 14 * 12
14 * 12 = 168.
That means the price of working for 12 hours is $168.
Hope this helped☺☺
Answer:
x = 51/4 or x = 12.75
Step-by-step explanation:
(2x - 1)2 = 49
4x - 2 = 49
4x = 49 + 2
4x = 51
x = 51/4 or x = 12.75
Hope you are able to understand it!
