The final answer is correct.

Answer:

f(5.5)≈27.32

Step-by-step explanation:

The exponential function which satisfy the f(4.5) = 23 and f(8) = 42 will be 10.60([tex]1.19^{x}[/tex]).

In mathematics, an exponential function is a relationship of the type y = ax, where x is an independent variable that spans the entire real number line and is expressed as the exponent of a positive number.

Suppose the exponential function is f(x) = a[tex]b^{x}[/tex].

As per the given,

f(4.5) = 23

Put x = 4.5 as

23 = a[tex]b^{4.5}[/tex]               (1)

As per the given,

f(8) = 42

Put x = 8 as

42 = ab⁸                  (2)

Divide equation (2) by (1) as,

ab⁸  / a[tex]b^{4.5}[/tex] = 42/23

[tex]b^{8-4.5}[/tex] = 42/23

b = 1.19

Again put into (2)

42 = a(1.19)⁸

a = 10.60

Thus, the function will be f(x) = 10.60([tex]1.19^{x}[/tex]).

Hence "The exponential function which satisfy the f(4.5) = 23 and f(8) = 42 will be 10.60([tex]1.19^{x}[/tex])".

Answer:

She gotta pay $550 or $551.25.

Step-by-step explanation:

To find percent, u gotta multiply 500 by .05, since it's 5 percent, nd 5 percent is .05. When I did that, I got 25, nd 25 is for one year, but u wanna kno for two years, so 25 + 25 is 50. $500 + $50 is $550.

After one year, the total price is $525, so Ian kno if u was supposed to do %5 of $525, but ehrn I did I got $551.25.

Ion really kno nun bout interest rates, but I kno one of these answers is right.

Answer:

b. 14 + (112 ÷ n)

Step-by-step explanation:

En esta pregunta la opcion que deberiamos elegir seria 14 + (112 ÷ n). En esta expresion primero se divide 112 por algun numero que es representado por el variable n. Luego de obtener el cociente de esta division, se le agrega 14 al cociente. Esto nos daria un valor nuevo y representa perfectamente la frase en esta pregunta... catorce más que el cociente de ciento doce y algún número

Answer:

First, let's define some variables.

x = # of cell phones sold.

y = total weekly income.

y = $5.25x + $80

Another way is

If $80 is her standard income per week, then there is no variation in how much she's earning for that chunk of money. The phones however are $5.25 per phone shes sold, and that exact number could vary, so we’d represent that with “x.” the correct equation to solve this would be y(total weekly income)= $5.25x + 80

Answer:

Step-by-step explanation:

Answer:

1.) slope = 2

2.) slope = [tex]-2\frac{2}{3}[/tex]

3.) slope = [tex]\frac{2}{3}[/tex]

4.) slope = [tex]\frac{1}{4}[/tex]

5.) slope = [tex]1\frac{8}{9}[/tex]

6.) slope = -2

7.) slope = -3

Step-by-step explanation:

In order to find the slope we have to divide they "y" value (the number of units by which the piece of antler goes up) by the "x" value the number of units by which the piece of antler goes to the side). Notice the if the antler moves to the left as it foes up then the "x" value is negative.

Now as I said before we know this......

Let "m" be the slope, then....

[tex]m = \frac{y}{x}[/tex]

So now we just have to plug in the y and x values for each antler and we will get the slopes for each one of them.

1.)

[tex]m = \frac{y}{x}[/tex]

[tex]m= \frac{4}{2}[/tex]

[tex]m = 2[/tex]

2.)

[tex]m = \frac{y}{x}[/tex]

[tex]m = \frac{4}{-1.5}[/tex]

[tex]m = -2\frac{2}{3}[/tex]

3.)

[tex]m = \frac{y}{x}[/tex]

[tex]m = \frac{2}{3}[/tex]

4.)

[tex]m = \frac{y}{x}[/tex]

[tex]m = \frac{1}{4}[/tex]

5.)

[tex]m = \frac{y}{x}[/tex]

[tex]m = \frac{8.5}{4.5}[/tex]

[tex]m = 1\frac{8}{9}[/tex]

6.)

[tex]m = \frac{y}{x}[/tex]

[tex]m = \frac{2}{-1}[/tex]

[tex]m= -2[/tex]

7.)

[tex]m = \frac{y}{x}[/tex]

[tex]m = \frac{3}{-1}[/tex]

[tex]m = -3[/tex]

Answer:

Step-by-step explanation:

As per the diagram we got:

As FH = 7x + 4 and EH = 9x - 2, we solve the following equation for x:

So each segment is:

Therefore:

So the variables are:

-x-y=-9

-3x-2y=-28

eliminate the x first

multiply the first system of equations by 3

(3)(-x)=-3x

(3)(-y)=-3y

(3)(-9)=-27

-3x-3y=-27

-3x-2y=-28

eliminate the systems of equations by subtracting

-3x--3x-3y--2y=-27--28

-3x+3x-3y+2y=-27+28

-y=1

multiply -1 for -y=-1  to get positive y

(-y)(-1)=(1)(-1)

y=-1

substitution method by using y=-1 into one of the system of equations

-x-y=-9

-x--1=-9

-x+1=-9

move +1 to the other side

sign changes from +1 to -1

-x+1-1=-9-1

-x=-10

multiply by -1 for -x=-10 to get positive x

(-x)(-1)=(-10)(-1)

x=10

answer:

x=10, y=-1
