BRAINLIESTTT ASAP!!! PLEASE ANSWER :)<br> Explain your answer.
baherus [9]

Answer:

x=14

Step-by-step explanation:

2(3x-4)=5x+6

first get rid of the parentheses by multiplying the  2

6x-8 = 5x+6

put like terms on one side of the equation. Start with the 5x, move it to the left side

(6x-8)-5x = (5x+6)-5x

x-8 = 6


Again, put like terms on one side of the equation. Move the 8 to the right side

(x-8)+8 = 6+8

=> x = 14


B)

4x - 3 = 2(x-1)

Start again by getting rid of the parentheses to make it a clean equation... aka distribute the 2:

4x-3 = 2x - 2

Move the like terms to one side of the equation. Start with x.. move 2x to the left:

(4x-3)-2x = (2x-2)-2x

=> 2x-3 = -2

Move the like terms to one side of the equation.Now move the -3 to the other side:

(2x-3)+3 = -2+3

=> 2x=1

Lastly, divide by 2 on both sides to find out what x is:

(2x)/2=1/2

=> x = 1/2


..so no, Charlie was incorrect.

If y = 5x − 4, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
Mama L [17]

Answer:

x can be any value, x will be the input, y will be the output.

Step-by-step explanation:

If x = 3, If x = 6, If x = 9,

y = 5x - 4

y = 5 (3, 6, or 9) - 4

y = 11, y = 26, y = 41.

These are all possible sets of ordered pairs, but ANY Real number can be represented as X, and it will need to be in an order. These numbers are all positive, so in this case, you just have to draw out Quadrant 1 in a Coor. Plane.

<u>X (Input)  I  Y (Output)</u>

3              I  11

6              I  26

9              I  41

See, when x increases by 3, Y increases by 15. If you go on, it will be the same path, same pattern.

Hope This Helps! :)

Raju’s mother is four times as old as Raju. After 5 years , her mother will be three
cluponka [151]

Answer:

Mother: 40 years old

Rakhi: 15 years old

Step-by-step explanation:

Solution :

Let present age of Rakhi = x years

Present age of Mother = 4x

5 years later

Age of Rakhi =x+5

Ag of Mother =4x+5

Given 4x+5=3(x+5)

4x−3x=15−5

⇒x=10

Mother's age =4x=40 years

Plug 10 in for x to find Rakhis age
