does anyone know how to do this?

Step-by-step explanation:

Determine points

We can use  f (5) = 7 and f (-2) = 0 to write two points.

(5 , 7)  &  (-2 , 0)

Find Slope

Slope  = (y₂ - y₁) ÷ (x₂ - x₁)

           = (7 - 0) ÷ (5 - (-2))

           = 1

Write the equation

equation in point-slope form (y - y₁) = m (x - x₁)

                                                (y - 0) =  1 (x - (-2))

                                                      y  =  x + 2

The answer is 11.

Step-by-step explanation:

You replace x with the value of 3 and solve.

Answer:

23

Step-by-step explanation:

3 × 2 × 4 - 3 + 2

Part A

x = amount of money she starts with

(4/9)x = cost of the dress

(5/9)x = amount of money leftover after buying the dress

note that 4/9 and 5/9 add to 1 to represent 100% of her money

(3/4)*(5/9)x = (15/36)x = (5/12)x = amount spent on shoes

We see that she spent 5/12 of her original amount of money on shoes.

-----------------------

We can look at a more concrete example if the previous section does not make sense.

Let's multiply the denominators 9 and 4 to get 9*4 = 36. Doing this trick will mean that the later steps won't involve decimal values.

Let's say she starts off with $36

Multiply that with 4/9 to get (4/9)*36 = 16. So in this hypothetical situation, the dress costs $16 and she's left with 36-16 = 20 dollars.

Multiply that 20 by 3/4 to get (3/4)*20 = 15

In this situation, the shoes cost $15

We'll then divide the cost of the shoes (15) over the original amount of money she started with (36)

15/36 = (3*5)/(3*12) = 5/12

-----------------------

=======================================================

Part B

From the first section in part A, we found that:

Add those two expressions

(4/9)x + (5/12)x = (16/36)x + (15/36)x = (31/36)x

This indicates that buying the dress and shoes will cost (31/36)x dollars, where x is the original amount of money Jing has to start with.

The amount left over is (5/36)x because 5/36 adds with 31/36 to get 1.

Take 1/3 of this to get:

(1/3)*(5/36)x = (5/108)x

Then set this equal to 18 and solve for x

(5/108)x = 18

5x = 18*108

5x = 1944

x = 1944/5

x = 388.80

--------------------

Let's check the answer

If she starts with 388.80 dollars, then the dress costs (4/9)*388.80 = 172.80

She's left with 388.80 - 172.80 = 216 dollars after buying the dress.

She then spends the remaining 3/4 of that on shoes. So (3/4)*216 = 162 dollars is spent on the shoes.

Jing now has 216 - 162 = 54 dollars left over.

1/3 of which is spent on the shoe bag, meaning it costs (1/3)*54 = 18 dollars

This confirms our answer.

Answer:

6 2/15

or 92/15

Step-by-step explanation:

To subtract mixed numbers, subtract the whole number parts of the mixed numbers and then subtract the fraction parts in the mixed numbers. Finally, combine the whole number answer and the fraction answer to express the answer as a mixed number. Subtract. Simplify the answer and write as a mixed number.

Answer:

6 2/15

Step-by-step explanation:

7 1/3 - 1 1/5

turn fractions in to common denominators

1/3 x 5 = 5/15

1/5 x 3 = 3/15

Now subtract fractions

7 5/15 - 1 3/15

= 6 2/15

Answer:

x^2 - y^2

Step-by-step explanation:

In the following problem, we can use the distributive property to simplify:

(x + y)(x - y)

We can start by multiplying the x's together, giving us x^2.

Next is the first x multiplied by -y in the second parenthesis. This gives us -xy.

Now, we can move on the the y in the first parenthesis: y times x(in the second parenthesis) is xy.

Lastly, we have y times -y which gives us -y^2.

(This process is shown in the image attached)

If we aa these together we get:

x^2 - xy + xy - y^2

If we add -xy and xy it would be 0 because if you add a number with it's opposite, they cancel out. We are just left with x^2 - y^2.

The Correct choices are :

Answer 45^(1/2)

Step-by-step explanation:

Use the pythagorean theorem to calculate the distance of the hypotenuse formed by the two siz=des that can be calculated from the given 2 points.  X is 3: (-2 -(-5)) = 3

y is 6: (9-3) = 6

We want the hypotenuse:  z^2 = x^2  + y^2

z^2 = 9 + 36

z = [tex]\sqrt45}[/tex]

It asks for the exact answer, so 45^(1/2) sems to be the only way to express this.

Answer: the vertical shift

Step-by-step explanation:

The vertical shift because the first equation j(x) is shifted up 11 while k(x) is shifted down 11. D in the equation y=acos/sin(bx-c)+d indicates if an object is moving vertically up or down.

The graph of k(x) have Vertical shifted down and graph of j(x) Vertical shifted up 11.

Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.

For example, this transformation moves the parallelogram to the right 5 units and up 3 units. It is written ( x , y ) → ( x + 5 , y + 3 ) .

Given:

j(x) = = 7 sin (6x- pi/2) +11

k(x) = 7 sin(6x- pi/2) - 11.

The +11 in j(x) shows the Vertical shift up.

and, the '-11' in k(x) shows the Vertical shifted down 11.

Hence, the difference is of the vertical shifting up or down.

Minibus

Line 1 = 3

Line 2 = 4

Total: At least 24

Media-blue

Line 1 = 13

Line 2 = 4
