Let the number = x

6x - 21 = 117

6x = 138

x = 138/6 = 23

Number is 23

Answer:

(1) 56 miles/hour

Step-by-step explanation:

We need to find the average rate of change from t = 2 to t = 9.

At t = 2 hours, d = 106 miles.

At t = 9 hours, d = 498 miles.

The average rate of change in function f(x) from x = a to x = b is

[f(b) - f(a)]/(b - a)

average rate of change from t = 2 to t = 9 =

(498 - 106)/(9 - 2) = 392/7 = 56

Answer: (1) 56 miles/hour

If x varies inversely as y, and x = 7 when<br> y=3, find y when x = 9.
RSB [31]

Step-by-step explanation:

x=k/y------(1)

k=xy

k= 7×3

k=21

from equation 1

x=k/y

y=k/x

y=21/9

y = 2.33

The equation of a circle uses the following formula:

(x - h)^{2} + (y - k)^{2} = r^{2}

The center of the circle is given by (h,k). Therefore, h = -2, and k = -5. r = 1, so we can find the equation from the information given to us.

Plug in your values.

(x + 2)^{2} + (y + 5)^{2} = 1^{2}

1^{2} = 1

The equation of this circle is as follows:

(x + 2)^{2} + (y + 5)^{2} = 1
