3(x-1) - 8 = 4(1+x) +5. Too hard, i keep getting confused
svet-max [94.6K]

3(x-1)-8=4(1+x)+5  

One solution was found :

                  x = -20

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    3*(x-1)-8-(4*(1+x)+5)=0  

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 ((3•(x-1))-8)-(4•(x+1)+5)  = 0  

Step  2  :

Equation at the end of step  2  :

 (3 • (x - 1) -  8) -  (4x + 9)  = 0  

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  -x - 20  =   -1 • (x + 20)  

Equation at the end of step  4  :

 -x - 20  = 0  

Step  5  :

Solving a Single Variable Equation :

5.1      Solve  :    -x-20 = 0  

Add  20  to both sides of the equation :  

                     -x = 20

Multiply both sides of the equation by (-1) :  x = -20

One solution was found :

                  x = -20

hope this is wht u wanted

If the domain of the function F = {(x, y) | 2x + y = 7} is {1, 2, 3}, what is the range?
Molodets [167]

Answer:

The range of the function is {1,3,5}.

Step-by-step explanation:

The function is defined as

F=\{(x,y)|2x+y=7\}

The set of all possible inputs is called domain and the set of output is called range.

In other words the possible values of x are elements of domain and the values of y are the elements of range.

Since the domain is {1,2,3} and the function is

2x+y=7

Put x=1

2(1)+y=7

2+y=7

y=7-2

y=5

Put x=2

2(2)+y=7

4+y=7

y=7-4

y=3

Put x=3

2(3)+y=7

6+y=7

y=7-6

y=1

Since the possible values of y are 5,3 and 1, therefore the range of the function is {1,3,5}

What are the coordinates of (-4,-2) rotating 90° counterclockwise?
RUDIKE [14]

Answer:

(2, -4)

Step-by-step explanation:

The rotation of an object <u>turns</u> the object around a <u>fixed point</u> called the center of rotation.  

A <u>rotation</u> of 90° counterclockwise means:

A 90° rotation counterclockwise with the origin (0, 0) as the center of rotation.

The rule for a counterclockwise rotation of 90° about the origin is:

(x, y) → (-y, x)

Therefore:

(-4, -2) → (2, -4)
