Look at the graph of the linear function. On a coordinate plane, a line goes through 4 points. Point A is (negative 2, negative
kondor19780726 [428]

Using it's concept, the rate of change between point C and point D is of 2.

<h3>What is the average rate of change of a function?</h3>

The average rate of change of a function is given by the <u>change in the output divided by the change in the input</u>. Hence, over an interval [a,b], the rate is given as follows:

r = \frac{f(b) - f(a)}{b - a}

Considering the points of the given linear function, we have that:

  • Point C: f(1) = 2.
  • Point D: f(2) = 4.

Hence the rate of change between point C and point D is given by:

r = (4 - 2)/(2 - 1) = 2.

Goshia [24]

Find common denominators. 10 is the common denominator. Multiply 2 to numerator and denominator of -3/5

(-3/5)(2/2) = -6/10

x + 1/10 = -6/10

Isolate the x. Subtract 1/10 from both sides

x + 1/10 (-1/10) = -6/10 (-1/10)

x = -6/10 - 1/10

x = -7/10

-7/10 is your answer for x

hope this helps

The dimensions of the nations smallest post office are 8 ft 4 in x 7 ft 3 in. Why would you use the measurement 8 ft 4 in. inste
allsm [11]

Answer:

The explanation in the procedure

Step-by-step explanation:

we know that

1\ ft=12\ in

In this problem is correct to use the measurement 8\ ft\ 4\ in instead of 7\ ft\ 16\ in  

because

16\ in=12\ in+4\ in=1\ ft+4\ in

therefore

7\ ft\ 16\ in=7\ ft\ +1\ ft+4\ in=8\ ft\ 4\ in
