Answer:

x = 10

Step-by-step explanation:

BF is two times AX so

2 ( 2x+10) = 5x+10

4x + 20 = 5x + 10

x = 10

1. the sum of the first n odd positive integers is 64. what is the value of n ?

77julia77 [94]

Step-by-step explanation:

1. 64=1+3+5+7+9+11+13+15 that is a total of 8 odd numbers so n=8

2.((new-old)/old)×100%=percentual difference

so ((new-$55)/$55)×100%=20%

new-$55=$55×0.2

new=$55+$55×0.2=$66

Select the correct function. Select the function with an average rate of change of 3 over the interval [1, 3].

Dovator [93]

Answer:

Function g(x)

Step-by-step explanation:

Given

See attachment for functions

Required

Which has an average rate of 3 over [1,3]

The average rate of change (m) is calculated as:

$m = \frac{f(b) - f(a)}{b -a}$

Where:

$[a,b] = [1,3]$

So, we have:

$m = \frac{f(3) - f(1)}{3 -1}$

$m = \frac{f(3) - f(1)}{2}$

From the table f(x), we have:

$f(3) = 6\\ f(1) = -2$

So:

$m = \frac{6 - -2}{2}$

$m = \frac{8}{2}$

$m =4$

From the graph of g(x), we have:

$g(3) = 4\\ g(1) = -2$

So:

$m = \frac{g(3) - g(1)}{2}$

$m = \frac{4 - -2}{2}$

$m = \frac{6}{2}$

$m =3$

Since only one of the function has an average rate of change of 3 over the given interval,

Then g(x) answers the question
