Step-by-step explanation:
please see it my steps to work this problem
First we need to combine like terms:
-18 + 15x = 12x - 18 + 3x
-18 + 15x = 9x - 18
-18 = 9x - 18 - 15x
-18 = -6x - 18
0 = -6x (the 18's cancel)
0 / -6 = x
0 = x
Answer:
The prime factors of 15 are: 1,3,5,15
The prime factors of 21 are: 1,3,7,21
The prime factors of 38 are: 1,3,13,39
The prime factor of 42 is : 1,2,3,6,7,14,21,42
We can use the points (2, 8) and (4, 12) to solve.
Slope formula: y2-y1/x2-x1
= 12-8/4-2
= 4/2
= 2
Based on the question, we need to put the equation in slope-intercept form (y = mx + b).
Let's solve for the y-intercept. (We can use the point 2, 8 to solve).
y = 2x + b
8 = 2(2) + b
8 = 4 + b
8 - 4 = 4 + b - 4
4 = b
Now, that we know what the slope and y-intercept is we can put this into the final equation.
y = 2x + 4 (third option)
Best of Luck!
