Slove (3x-2)=(2x-1)/(2) show step by step

Answers

Answer:

x= 3/4

Step-by-step explanation:

[tex](3x - 2) = \frac{(2x-1)}{2}[/tex]

2(3x - 2) = (2x - 1)

6x - 4 = 2x -1

4x = 3

x= 3/4

Answer:

x=3/4

Step-by-step explanation:

Remove parentheses.

3x-2=\frac{2x-1}{2}3x−2=22x−1

Multiply both sides by 22.

6x-4=2x-16x−4=2x−1

Add 44 to both sides.

6x=2x-1+46x=2x−1+4

Simplify  2x-1+42x−1+4  to  2x+32x+3.

6x=2x+36x=2x+3

Subtract 2x2x from both sides.

6x-2x=36x−2x=3

 

Simplify  6x-2x6x−2x  to  4x4x.

4x=34x=3

 

Divide both sides by 44.

x=\frac{3}{4}x=43

Given: g(x) = 4 - (x + 3)^2
find the x-intercept​

Answers

X intercept is when the function (y) = 0.

0 = 4 - (x+3)^2

(x+3)(x+3) = 4

x^2 + 6x + 9 = 4

x^2 + 6x + 5 = 0

To factor, we find what multiplies to 5 and adds to 6. In this case, it’s 5 and 1.

(x+5)(x+1) = 0

x values of the intercepts are -5 and -1.
The coordinates are (-5,0) and (-1,0).
it is -5 and -1 hope this helps
