Answer:
x = -5
Step-by-step explanation:
-5(1 - 5x) +5(-8x - 2) = -4x – 8x
First lets simplify each side of the equation.
-5+25x-40x-10 = -4x-8x
Combine like terms
-15x-15=-12x
Add 15x to both sides (addition property of equality)
-15=3x
Divide each side by 3 (division property of equality)
x=-5
The answer is x = -5
If arctan 4/3 = the tangent of that angle will be 4/3 , opposite 4 over adjacent 3
Now, you only have to take the sin of that angle it's opposite 4 over hypotenuse 5.
You will get that the answer is 4/5
hope this helps
So first, you need to identify the parts of this equation.
3x is the slope of the line, which is 
.
-5 is the y-intercept. or the part of the line that touches the y-axis.
The first thing you want to do is plot the y-intercept. SO, go to the y-axis and find -5. Plot your point there.
Now, use the slope to find your next plot. Since slope is 
, you go up three, and over to the right one.
Now, draw a line connecting the dots. Your slope should be positive and look like > /

A. one solution
B 4(2x-5) = 4
2x-5 = 1
2x = 6
x=3
