write a linear function in slope intercept form only that corresponds with this table​

Answers

y = 3x + 1

Because,
slope intercept form is y=mx+b
Where y is the y values, m is slope, x is x values, and b is y-intercept

First, to find the slope use rise/run, so rise (from 10 to 13) is 3 and run is (from 3 to 4) is 1, 3/1=3

Next to find y-intercept plug in the slope and some x and y values,
10=3(3)+b
10=9+b
1=b
So then the equation is y=3x+1 you can check by plugging stuff in and also I graphed it so I’ll add a picture

This is my first time answering questions so if I got something wrong ask or something hope this helps :)

Find the average rate of change

Answers

Replace x with 1 nd solve, then replace x with 3 and solve:

x^3 - 2x^2 +3x

When x = 1:  1^3 -2(1)^2 +3(1) = 3 -3 +3 = 3

When x = 3: 3^3 -2(3)^2 + 3(3) = 27 -18 +9 = 18

The difference between the two solutions is 18-3 = 15

The difference between the two x values = 3-1 = 2

The rate of change is 15/2  or 7.5 as a decimal.

Help me please I need the answer for questions 9 part A and Part B

Answers

Answer:

Part A:

c = 4 + 1.50h

c = 1 + 3h

Part B:

2 hours

$7

Step-by-step explanation:

Part A:

Number of hours = h

Cost = c

Cost for Ice Dream:

c = 4 + 1.50h

Cost for Skating Paradise:

c = 1 + 3h

Part B:

Set the equation equal to each other and solve for h:

4 + 1.50h = 1 + 3h

Collect like terms

4 - 1 = -1.50h + 3h

3 = 1.50h

Divide both sides by 1.50

3/1.5 = h

2 = h

h = 2

The cost for both locations would be equivalent at 2 hours

✔️The cost is:

4 + 1.50h = 1 + 3h

4 + 1.50(2) = 1 + 3(2)

4 + 3 = 1 + 6

7 = 7

The cost is $7

➜︎Question
Describe what you notice when you create the inverse ratio.

- How do you describe it?

- What do you notice?

- How do you create it?

➜︎Answer
A function composed with its inverse function yields the original starting value. Think of them as "undoing" one another and leaving you right where you started. Basically speaking, the process of finding an inverse is simply the swapping of the x and y coordinates.

- You can describe a inverse ratio by saying how it works

- You can notice the difference

The circumference of a circle is _______

A. the length of the radius
B. the distance around the circle
C. the length of the diameter
D. 270​

Answers

Answer:

B. the distance around the circle

Step-by-step explanation:

To easily answer this question, take a closer look at the given answer choices.

A says, "the length of the radius." Don't let the extra words trick you! This answer choice is just describing a radius. The term, "the length of--" is just there to trick you and to make you overthink. This answer choice is not correct because a radius =/= a circumference.

C says, "the length of the diameter." This is the exact same trick in choice A. Once you ignore the term, "the length off," you see that this answer choice is just describing a diameter. This answer is also incorrect because a diameter =/= a circumference.

D just says "270." This answer choice should not be considered, as there's no numbers involved in the question. The question is just looking for the definition of a circumference. Continually, not every circle's circumference is going to be 270. For these reasons, D is also an incorrect choice.

This leaves answer choice B. After eliminating the other answers, B becomes the remaining and correct choice. "The distance around the circle," is the only and correct definition of a circumference!

Answer:

Solution :

B

Know More :

The length of radius is not known as circumference.

Circumference or perimeter is same.

Area of circle = πr²

Perimeter of circle = 2πr

Let f(x) = 3x^2+5, g(x)=3x-4. Find the following value or expression
(F*g)(x)=

Answers

Answer:

(f οg )(x) = 27 x² -36 x + 53

Step-by-step explanation:

Explanation:-

Given the function f(x) = 3 x² +5 and g(x) = 3x-4

(f οg )(x) = f(g(x)

             = f(3x-4)

             = 3 ( 3x-4)² +5  ( ∵  f(x) = 3 x² +5)

            =  3 ( 9 x² - 2(3x)(4)+(4)²) +5

           = 3 ( 9 x² -12 x + 16) +5

          = 27 x² -36 x + 48 +5

         = 27 x² -36 x + 53

Final answer:-

(f οg )(x) = 27 x² -36 x + 53

May someone please help me out with this? Look at the image above. How do I do this? May someone help me out please

Answers

Answer:

u = 9

Step-by-step explanation:

angle c and a are congruent so take the 2 angles and turn them into an equation

u + 99 = 12u

subtract 1u from both sides, you're left with 99 = 11u

now, divide each side by 11

now you'll get the value of u which is 9 (u = 9)

since 99/11 is 9 that's the value of u.

Hjqjzjzj is a complete* of the following elements has the largest atomic size in the world is the difference between human rights

Answer:

We know:

A+2B=777

2A+B=789

 

Let's rearrange the first equation to solve for A:

A=777-2B

 

Now let's plug 777-2B in for A in the second equation, and solve for B:

2(777-2B)+B=789

1554-4B+B=789

1554-789=3B

765=3B

B=255

 

Now we can substitute 255 in for B in the first rearranged equation, and solve for A:

A=777-2(255)

A=777-510

A=267

So candy bar A has 267 calories, and candy bar B has 255
