Here's a graph of a linear function. write the equation that describes that function.

Answer:

613.87 dollars

Step-by-step explanation:

Times 400 by 1.055 and you'll get 422 dollars. Keep doing this with the product (Result of you multiplying the previous answer by 1.055) eight times and you'll get 613.87 dollars

Answer:

A = $400e^(0.055·8) ≈ $621.08

Answer:

Step-by-step explanation:

From the question, we are to relate the amount the teacher spent to the expression 9(7-x).

Since the teacher does not have to spend all the $36, this means that he spent amount less than $36 but not equal to $36. Hence the best inequality sign that relates both expression is a less than sign (<) as shown;

9(7-x) < 36

hence the required inequality is 9(7-x) < 36

Answer:

v=9

Step-by-step explanation:

-18 = 7v + 9 - 10v

combine like terms

-18 = -3v + 9

-9             -9

-27 = -3v

divide both sides by -3

9 = v

or

v = 9

Step-by-step explanation:

Makes NO sense

Answer:

B.x+2

Step-by-step explanation:

Answer:

3+2w=l

2(l+w)=7 1/3

2(3+2w+w)= 7 1/3

6+6w= 7 1/3

-6 both sides

6w=1 1/3

/6 both sides

w=2/9

2/9*2=4/9+3=3 4/9

4/9*3 4/9= 1 43/81

1 43/81

Answer:

a) 3.55 k.m

b) 10.75 k.m

c) 33.o6 k.m

Answer:

1) y = 0.3x + 1000

2) slope = 0.3

The slope is the fraction of the monthly sales that is added to your salary.

3) y-intercept = 1000

The y-intercept is the fixed part of the salary, $1000.

4) The salary is $2500

Step-by-step explanation:

1)

monthly salary = fixed part + variable part

The fixed part is $1000. Every month you receive $1000 no matter the amount of sales.

The variable part varies according to the amount of sales. You get 30% of the of the monthly sales. Let the monthly sales be x. The variable part is 0.3x

Let the monthly salary = y.

y = 1000 + 0.3x

y = 0.3x + 1000

2)

slope = 0.3

The slope is the fraction of the monthly sales that is added to your salary.

3)

y-intercept = 1000

The y-intercept is the fixed part of the salary, $1000.

4)

In this case, x = 5000

y = 0.3x + 1000

y = 0.3(5000) + 1000

y = 1500 + 1000

y = 2500

The salary is $2500.

Answer:

3

Step-by-step explanation:

To find the slope of a line going through two points, (x₁, y₁) and (x₂, y₂), we can use the following formula: [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]. Note that it doesn't really matter which points we call (x₁, y₁) or (x₂, y₂).

Let's call (x₂, y₂) = (0, 5) and (x₁, y₁) = (-2, -1). Now, we can plug in the values for x, y₁, x₂, and y₂ into the formula.

We have:

[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{5-(-1)}{0-(-2)} =\frac{5+1}{0+2} =\frac{6}{2} =3[/tex]

Therefore, the slope of the line is 3. Hope this helps!

Answer:

[tex]\sqrt{77}[/tex]

Step-by-step explanation:

[tex]\sqrt{7} \sqrt{11}[/tex]

Apply radical rule: [tex]\sqrt{a} \sqrt{b} =\sqrt{a*b}[/tex]

[tex]\sqrt{7}\sqrt{11} =\sqrt{7*11}[/tex]

[tex]=\sqrt{7*11}[/tex]

Multiply the numbers: [tex]7*11=77[/tex]

[tex]=\sqrt{77}[/tex]

Answer:

y = 8

x = -2

Step-by-step explanation:

(If you are cancelling the y form the equation to find x first then subtract the equation as the signs are the same or else if you are cancelling the x first then add the equations as the signs are different)

y-12x=12 l cancelled the x from the equation to

y+2x=4 find y

_____

2y = 16

y= 16/2

y=8

8 in eqn no 1

y-2x=12 replace the y with 8 and find x

8-2x=12

8-12=2x

-4=2x

-4/2=x

-2=x

Answer:

Wheres the picture?

Step-by-step explanation:

Hello!

Solve for x.

2x+3y=z

Step 1: Add -3y to both sides.

2x+3y+−3y=z+−3y

2x=−3y+z

Step 2: Divide both sides by 2.

2x/2=−3y+z/2

Answer:

0.34 gallons of water

Step-by-step explanation:

Mr Percuoco is working the fish bowl toss

He used 13.6 gallons of water to fill 40 fish bowls

Therefore the gallons of water in each fish bowl can be calculated as follows

= 13.6/40

= 0.34

Hence there are 0.34 gallons of water in each fish bowl
