Answer:

Step-by-step explanation:

Answer: X = - 5

Step-by-step explanation:

21 / - 4.2 = -5

Answer:

[tex]\huge\boxed{\sf x = -5}[/tex]

Step-by-step explanation:

-4.2x = 21

Divide both sides by -4.2

-4.2 x / -4.2 = 21 / - 4.2

x = -5

We gotta divide -4.2 instead of 4.2.

Answer:

The answer is A.

Step-by-step explanation:

This is because the Triangle is being rotated counter clockwise 90 degrees, then reflected over the Y axis.

So, point (-6, 8) would become (-8, -6), and so forth.

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:

Step-by-step explanation: 85

Answer:

Step-by-step explanation:

Use the vertex form to determine the values of

a

,

h

, and

k

and use these values to find the direction the parabola opens, vertex, focus, axis of symmetry, and directrix.

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]

-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  

Answer:

The final answer is correct.

Answer:

The notation g(10) means g(x=10).  So just set the x-value in g(x) equal to 10:

g(x) = -3x + 1

g(10) = -3*10 + 1

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
