Right answer will get a BRAINLIST

Answer:

x= 13.5

Step-by-step explanation:

f(x) = 2x + 9

f(x) = 36

Set the 2 equations equal to each other;

2x + 9 = 36

Subtract 9 from both sides;

2x = 27

Divide both sides by 2;

x = 13.5

Check:

f(x) = 2x + 9

f(13.5) = 2(13.5) + 9= 27 + 9 = 36

Answer:

Actually, it's C multiplication Cutty you can't be giving Wrong answers.

Step-by-step explanation:

It's C Multiplication because Were using the PEMDAS technique and this stands for

P- Parenthesis

E- Exponents

M- Multiplication

D- Division

A- Addition

S- Subtraction

So if you see in the Pemdas technique It will be C Multiplication.

Answer:

D. identity

Step-by-step explanation:

- 6a + 3 = - 3(2a - 1)

First, distribute -3 within the parenthesis.

- 6a + 3 = - 6a + 3

Subtract 3 from both sides of the equation

- 6a = - 6a

Divide - 6 on both sides of the equation

a = a

We know because both sides have the same equation, and that it is true, that this equation has infinite solutions, so the answer would be D. Identity

For those who don't know, identity in algebra means that the equation is true no matter what is substituted in for the variable. It will always be true.

I hope that this helps! :)

Question 8: w=7200

Step-by-step explanation:

2400/2=1200 is c is 1 so 1200x6=7200

Answer:

m = 0.28571428571

or 0.29(to the nearest tenth)

Step-by-step explanation:

First, distribute

12(−1.4m+0.4)=

-16.8m + 4.8 =

Now move the constant to the right.

-16.8m + 4.8 =

-16.8m = -4.8 =

Now divide,

-16.8m = -4.8 =

m = 0.28 or 0.29

Answer:

-n^3 – 5n + 4

Step-by-step explanation:

f(n) = -n^3 – 4

g(n) =  -n +4

f(n)+ g(n) = (-n^3 – 4n)+(-n +4)

               = (-n^3 – 4n -n +4)

               = -n^3 – 5n +4

1. the perimeter of the first question is 22.5

2. true

these are the only ones i remember how to do!

sorry :(

Hopefully someone fills in the rest of the answers!!!

Answer:

Question 1:

8/12 = 4/6 = 3/x

0.6 = 0.6 = 3/x

It is a similar triangle, therefore 3/x = 0.6

x = 5 because 3/5 = 0.6

Question 2

You did that correct :)

Question 3:

"Check all that apply"

B

D

Question 4

You got question 4 wrong since similar triangles have similar ratio.

8/10 = 8/10 = 10/14

0.8 = 0.8 = 0.7

Correct answer for question 4 is B("No they are not similar because the ratios are not equal")

Question 5

The Quadrilaterals are similar. Therefore:

22.4/14 = 12.8/8 = 12/7.5 = 26/x

1.6 = 1.6 = 1.6 = 26/x

Meaning 26/x = 1.6

x = 16.25

Because 26/16.25 = 1.6

Hope that helps :)

Answer:

the graph is of a cubic function.

Step-by-step explanation:

f(x)= x^3. It should have at least one zero

The graph shows cubic polynomial.

A polynomial is an equation that solely uses the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are also known as indeterminates.

Given:

In the graph the number of times the graph touches the x- axis it will have that many zeroes or solution for the polynomial.

The given graph touches the x-axis three times which shows the polynomial will have three solution and the degree of the polynomial is 3.

Hence, the graph shows cubic polynomial.

Answer:

red

Step-by-step explanation:

The complete question is as follows;

At a soccer tournament 12 teams are wearing red shirts, 6 teams are wearing blue shirts, 4 teams are wearing orange shirts, and 2 teams are wearing white shirts. For every 2 teams at the tournament, there is 1 team wearing ____ shirts

Solution;

The total number of teams we have is 12 + 6 + 4 + 2 = 24 teams

Now looking at the number of teams wearing red shirts , we can see 12 of them which is exactly half the total number of teams

So what this means is that for every two teams at the tournament, there is 1 team wearing red shirts

Answer: -1 ≤ x ≤ 4.

Step-by-step explanation: To solve this problem, we first add 7 to the inequality: -4 ≤ 4x ≤ 16. Then we divide the entire equation by 4 to get -1 ≤ x ≤ 4.

Given:

There are 4 quarts in a gallon.

She wants to convert 6 quarts to a gallon.

To find:

Whether she should multiply 6 by 4 or divide 6 by 4 to find her answer.

Solution:

We have,

[tex]4\text{ quarts}=1\text{ gallon}[/tex]

[tex]1\text{ quarts}=\dfrac{1}{4}\text{ gallon}[/tex]

[tex]6\text{ quarts}=\dfrac{6}{4}\text{ gallon}[/tex]

Here, 6 quarts is equal to [tex]\dfrac{6}{4}[/tex] gallon. It means we need to multiply 6 by 4 in [tex]4\text{ quarts}=1\text{ gallon}[/tex] to find the answer.
