Find the inverse of f(x) = -4+7/2x

Answer:

B. False

Step-by-step explanation:

Answer:

Step-by-step explanation:

General equation of a line is y= mx+b,

where m is the slope and b is the y- intercept

For points (-5, -8) and (-4, -6) the slope is

m= difference in y / difference in x

m = [-6 - (-8)] / [-4 - (- 5)] = (-6+8)/(-4+5) = 2/1 =2

Now we know that y= 2x+b , to find b substitute the coordinate (x, y) with coordinate (-4, -6) -you could pick the other point if you want will work because both points are on the line.

-6 = 2(-4) +b , multiply

-6 = -8 + b, add 8 to both sides

-6+8 =b , add

2 =b

The equation of the line that passes through the points (-5, -8) and (-4, -6) is

y= 2x+2

First of all, you will find the gradient. The formula for finding the gradient is y2-y1 /x2-x1. - 6--8/-4--5.If two negatives meet they change to positive. - 6+8/-4+5=2/1,therefore the gradient is 2,after that then you will find the equation of the line. The formula for finding the equation of the line is y-y1=m(x-x1). y-(-8)=m(x--5),y+8=2(x+5),y+8=2x+10,y=2x+2.

Answer:

D

Step-by-step explanation:

Answer:

38

Step-by-step explanation:

10 + 4 + 2 + 9 = 25

That's the stuff we're given.

Now the other sides.

10 - 2 = 8,

9 - 4 = 5,

25 + 8 + 5 = 38

Answer: 5 lessons with 5$ left over

Step-by-step explanation:

You can buy 5 lessons because 50 is 5/8 of 80, and 50 + 80 + 80 + 80 + 80 = 370

Answer:

3 times a value is equal to twice as much as it's predecessor.

Answer: The smaller piece is 750m long.

Step-by-step explanation:

let the smaller piece be x

so

150m + x + x = 1650

150 + 2x = 1650

or, 2x = 1500

so, x = 750 m

Answer:

It will ALWAYS be true!

Step-by-step explanation:

Inputting any real or imaginary numbers such as i or e, (which are also known as complex numbers), and when put in the place of x will ALWAYS equal one another. You could put 1, 2, 3, etc. all the way up to infinity and still get the two equations equal to each other.

The Salinas Plan

The Salinas Plan is a Ten-Year Plan designed to provide the City with a path forward on maintaining a long-term balanced budget while preserving City services and addressing the affordable housing crisis.  The Salinas Plan may be found here.

The Salinas Plan Story

The Salinas Plan was presented to the City Council by representatives of the National Resource Network on December 4, 2018.  The Salinas Plan represented over a year of work analyzing the City's fiscal situation and current housing policies.  The Salinas Plan presented the following key findings:

- The City of Salinas is on a fiscally unsustainable path.  While the City's revenues are growing at 2.4% per year, expenditures are growing at 2.9% per year.

Answer:

The rate of change is 185.

It tells us that Fuji's expenses increase by $185 for each additional crib made.

Step-by-step explanation:

In a linear equation, the rate of change is the change in y over the change in x.

In this situation, that means how much the cost will change based on the amount of cribs that Fuji has to make.

Since labor and material costs for each crib cost $185, 185 is the rate of change.

For every additional crib that Fuji makes, the cost will increase by $185.

So, the rate of change is 185 and it tells us that Fuji's expenses increase by $185 for each additional crib made.

Answer:

x = 456

Step-by-step explanation:

X/24 = 19

Multiply 24 by each side

X/24 * 24 = 19*24

x = 456

Answer:

  2387.1 ft

Step-by-step explanation:

I find a spreadsheet to be a convenient tool for repeated calculations using the same formula. Here, the distance between two points is given by ...

  d = √((x2 -x1)² +(y2 -y1)²)

For example, the distance between the first two points is ...

  d = √((300 -(-350))² +(-400 -200)²) = √(422500 +360000) ≈ 884.59

Other distances are calculated the same way. The results are shown in the attached spreadsheet, which also adds them up.

The path length is 2387.1 feet.

According to the table,

• € 1 = R 12,75

• $ 1 = € 0,70

• $ 1 = R 8,89

Then

€ 250 × (R 12,75 / € 1) = R 3.187,5

$ 1300 × (€ 0,70 / $ 1) = € 910

$ 680 × (R 8,89 / $ 1) = R 6.045,2

[tex]\\ \rm\Rrightarrow Slope=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\\ \rm\Rrightarrow Slope=\dfrac{-7-1}{3+2}[/tex]

[tex]\\ \rm\Rrightarrow Slope=\dfrac{-8}{5}[/tex]

Answer:

9.06 units

Step-by-step explanation:

The distance formula for points on a graph is basically the Pythagorean Theorem

√(x2 - x1)² + (y2 - y1)²

Plug in the values and you'll get √82, which equals about 9.05539, or 9.06

Correct choice is D

Answer: x = 16

Step-by-step explanation:

4x + 4x-2 + 3x + 6 = 180 (being sum of triangle)

or, 11x + 4= 180

or, 11x = 176

so, x = 176/11

so, x = 16  

Answer:

Below

Step-by-step explanation:

To find the total cost of Jorge's dinner, all you need to do is multiply the cost of his dinner by 1.15 (the tip amount)

     $45.50 x 1.15 = 52.325

                            = $52.33
