Step-by-step explanation:
The answer to the equation 1/3(6x-15)= 1/2(10x-4) is D. -1
Answer:
2
Step-by-step explanation:
Use the slope formula, given the available points on the line.
m = y2-y1/x2-x1
Plug in the x and y values.
m = 10-2/6-2
Simplify.
m = 8/4 = 2/1 = 2
Is there picture where the x is?
perimeter is the length of the sides. not enough info
Answer (2 answers):
x = -2/5, x = -14/5
Step-by-step explanation:
First step is to try and get the absolute value by itself on one side and everything else that's not inside the absolute value on the other side.
9|5x+8|=54
|5x+8| = 54/9
|5x+8| = 6
Remember how absolute values turn everything positive? For example
|-4|=4, but |4|=4 as well. So we must do the same to our problem by splitting up the absolute equation into two parts.
|5x+8| = 6 and |-(5x+8)| = 6
now solve the first equation.
(Just remove the absolute value sign and solve it normally)
5x+8 = 6
5x = -2
x = -2/5
Now solve the other equation
-(5x+8) = 6
-5x - 8 = 6
-5x = 14
x = -14/5
