Answer:

y = 5x + 28

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 5 , thus

y = 5x + c ← is the partial equation

To find c substitute (- 6, - 2) into the partial equation

- 2 = - 30 + c ⇒ c = - 2 + 30 = 28

y = 5x + 28 ← equation of line

Answer:

67

Step-by-step explanation:

Answer:

The mean absolute deviation is 1

Step-by-step equation =

Take all of the numbers and add them together.

4+1+2+1+0+1= 9

Then divide by how many numbers there are. In this word problem its 6.

Divide 9 by 6.

9 ÷ 6 = 1.5

So 1.5 would be our mean.

To find the mean absolute deviation subtract our mean and our original numbers.

1.5 - 4 = 2.5

1.5 - 1 = 0.5

1.5 - 2 = -0.5

1.5 - 1 = 0.5

1.5 - 0 = 1.5

1.5 - 1 = 0.5

Add all of those numbers together.

2.5 + 0.5 + 0.5 + 0.5 + 1.5 + 0.5 = 6

Even though one of the numbers was a negative answer we add it as a positive because the mean absolute deviation can never be negative

Divide by the amount of numbers you added.

6 ÷ 6 = 1

So the mean absolute deviation is 1

Hey there! I'm happy to help!

From G to I is the total distance of the line (92). G to H is the first portion of the line (72) while H to I is the other portion.

To find H to I, simply subtract 72 from 92!

92-72=20

The distance from city H to city I is 20 miles.

Have a wonderful day! :D

Answer:

A,B,C,F

Step-by-step explanation:

The correct answer would be options (A), (B), (C), and (F)

(A) positive: (–2, 2)

(B) range: (–3, 4]

(C) domain: (–3, 3]

(F) increasing: (–3, –1)

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

The vertical span of the range is from y > -3 to y = 3. The interval for this is [(-3, 3].

The horizontal range, from x > -3 to x = +4, represents the domain. This is represented by the interval [(-3, 4].

The graph decreases to the right, it gets smaller. There is no mention of the endpoints. The x values are in the range (-1, 4).

The graph is increasing where it goes up to the right. The endpoints are generally not included. The x-values are in the interval (-3, -1).

The region of the graph that is above the x-axis is positive. The interval contains x. (-2, 2).

Answer:

B.) 33

Step-by-step explanation:

15/5=3

6x3=18

18+15=33

The ratio shows how many times one value is contained in another value.

If the ratio of Red and blue is 6:5 and uses 5 pints of blue color.

The total pints of paint used in total is 33 pints.

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

The ratio of minutes and minutes in 1 hour is 60 : 3600

We have,

Purple color:

Red : Blue = 6 : 5

Let,

Red colour = 6x

Blue color = 5x

Now,

Blue color = 15 pints

5x = 15 pints

x = 15/3

x = 3 pints _______(1)

Now,

Total color.

= Red + Blue

= 6x + 5x

= 11x

Now,

From (1) we get,

= 11x

= 11 x 3

= 33

Thus,

If the ratio of Red and blue is 6:5 and uses 5 pints of blue color.

The total pints of paint used in total is 33 pints.

Answer:

B) y=x+2; y=5

Step-by-step explanation:

The rules that define the graphed function are y = x + 2; y = 5

The function is a piecewise function

There are two lines on the graph.

The first line has the following points

(0,2) and (3,5)

Express 2 and 5 as a sum of 2

(0,0 + 2) and (3, 3 + 2)

This means that the y value is the sum of 2 and the x value.

So, we have:

y = x + 2

The other line has a constant value of 5 for all x values

So, we have:

y = 5

Hence, the rules that define the graphed function are y = x + 2; y = 5

Answer:

[tex]99 + 50x = 549[/tex]

Alternatively you can write it as;

[tex]50x - 450 = 0[/tex]

Step-by-step explanation:

One time service fee=$99

Rate of service=$50/hour

let unknown hours=x

Therefore the equation is

[tex]99 + 50x = 549[/tex]

or you can further simplify it to:

[tex]50x - 450 = 0[/tex]

And you can then solve for x to be 9 hours.

Answer:

f^-1(x) = x - 5

Step-by-step explanation:

f(x) = x + 5

y = x + 5

x = y + 5

y = x - 5

f^-1(x) = x - 5

Answer:

f^ -1(x) = x - 5

Step-by-step explanation:

y =x+5

To find the inverse, exchange x and y

x = y+5

Solve for y

Subtract 5 from each side

x-5 = y+5-5

x-5 = y

The inverse is  x-5

Answer:

Options (1) and (2)

Step-by-step explanation:

Properties of a polynomial,

1). A polynomial having division by a variable can't be defined as a polynomial.

  Example:

   (y² + [tex]\frac{x}{1+x}[/tex])

2). A polynomial can't have a negative exponent.

  Example : [tex](x^{-2}+y-6)[/tex]

3). Polynomials don't have the radicals.

  Example : y² + x√3

4). A polynomial can't have a fraction exponent.

   Example : [tex]x^2+x^{\frac{1}{2}}-1[/tex]

By these properties, Options (3) and (4) are not the polynomials.

Options (1) and (2) are the correct options.

Answer:

Step-by-step explanation:

f(x)=x² - 2x + 7

To find f(-3) substitute the value of x that's - 3 into f(x). That is for every x in f (x) replace it with - 3

We have

f(-3) = (-3)² - 2(-3) + 7

= 9 + 6 + 7

We have the final answer as

f(-3) = 22

For question 2 the slope is 1. So what you do is get the points you need to put on the graph and move them up one. Like how you did on question 1.

(0.5, 5) (1, 10) (1.5, 15) (2, 20) (2.5, 25)

Question 3 is the same thing but the slope is now 2. Then you would have to pin the points as...

(1, 2) (2, 4) (3, 6) (4, 8) (5, 10)
