Answer: 5x = 12 + 3

5x = 15 (divide both sides by 5 to get x)

Step-by-step explanation:

$5x/5 = 15/5\\x = 3$

Answer:

X = 3

Step-by-step explanation:

5X - 3 = 12

add 3 to both sides of the equal sign

5X = 15

divide 5 to both sides of the equal sign

X = 3

<h3>What is an Expression?</h3>

In mathematics, an expression is a set of numbers, variables, and mathematical operations formed according to rules.

Given ;

$3x(x - 12x) + 3x^2 - 2(x - 2)^2$

To solve the algebraic expression,

$3x(x - 12x) + 3x^2 - 2(x - 2)^2\\\\3x(x - 12x) + 3x^2 - 2(x^2 - 4x + 4)\\\\3x(x - 12x) + 3x^2 - 2x^2 + 8x - 8\\\\3x^2 - 36x^2 + 3x^2 - 2x^2 + 8x - 8\\\\-33x^2 + x^2 + 8x - 8\\\\\\-32x^2 + 8x - 8\\$

To solve the problem we must know about the Like terms and expressions.

Part A:

From the graph, it seems that the lines intersect at (3,-1)... This seems to be the solution...

Part B:
g(x) is a negative line, and the slope is 2 (from rise/run). Y int. = 5. So, the equation is -2x+5. Plug in some numbers for this; say 1 and 2. The coordinates would be (1,3) and (2,1).

Part C:
The 2 graphs seem to intersect at (0,5), so this is the solution...

ALL of this is based on only looking at the graph, which is no better than drawing lines on the sand.. For example, the y intercept for g(x) could be 4.9 or 5.1, and I don't know the equation for f(x)... Based on the info I have, gave my best answers..

Hope this helps..
