1. -3x+32= -x-12 2. 8x+16=x+9 3. 3x + 2 = 2x -55 I need all the steps to all three of those questions

Answers

Answer 1

Answer:

Step-by-step explanation:

1. - 3x + 32 = - x - 12

-3x + x = - 12 - 32

-2x = - 44

x = 44/2 = 22

2. 8x + 16 = x + 9

8x - x = 9 - 16

7x = - 7

x = - 7/7

= - 1

3. 3x + 2 = 2x - 55

3x - 2x = - 55 - 2

x = - 57

A function f(x) is shown below.

f(x) = x + x + x

Write an equivalent form of f(x) in function notation that contains only one term on the right side of the equation.

Answers

Answer:

f(x) = 3x

Step-by-step explanation:

when adding x (the same variable) to eachother when there is nothing in front, you always assume the coefficient is 1. since there are 3 x's, (1)x+(1)x+(1)x=3x. hope this helps:)

It would be 0 because 0=3x and 3x=0 so the answer would be x=0

Answer:

Given :  the sample space of​ two-digit numbers that can be created using the digits 9,7,1, and 8.

To Find : probability of choosing a number from the sample space that contains both 7 and 8.

Solution:

TREE DIAGRAM

       9                    7                      1                    8

       ↓                     ↓                      ↓                  ↓

9     7     1     8     9    7    1     8    9   7   1    8     9   7   1    8

Total Sample space  =  16

Contains both 7 and 8

is ( 7 , 8)  or ( 8 , 7)

Hence probability of choosing a number from the sample space that contains both 7 and 8.  =  2/16

= 1/8

= 12.5 %

x = 6 cm

Step-by-step explanation:

The local business will donate $5.00 for every 10 tickets sold. Let x represent tickets sold, and y represent dollars donated. Student A claims that the equation is y = 2x. Student B claims that the equation is y = 1

x. Explain who is correct.

Answers

Answer:

If we let x be the number of ticket sold and y be the amount in dollars donated then, the equation would be,

                                     x = 2y

We can check our answer by substituting the given,

                                     10 = 2(5)

                                      10 = 10

The equation can also be written as,

                                    y = (1/2)x

Student B is correct.  

Answer:

Sample Response/Explanation: The point that represents what the local business will donate is (10, 5). After testing the point in both equations, you can see that student B wrote the correct equation; 5 = 12(10).
