First you add like terms, so in this case it would be 2x+3x, which would together make 5x=10. Then to get x isolated divide 10 by 5 and x=2
The value of z is zero
Step-by-step explanation:
The slope is the steepness of the line.
The formula for slope is given by:

Here
(x1,y1) = (1,z)
(x2,y2) = (2,8)
So,

The value of z is zero

Answer:
8.5
Step-by-step explanation:
By the pythagorean theorem, we know that (leg1)^2 + (leg2)^2 = hypotenuse^2. to see the proof refer to the following link: http://jwilson.coe.uga.edu/EMT668/EMT668.Student.Folders/HeadAngela/essay1/Pythagorean.html
plugging in what we know we have 16^2 + leg^2 = 20^2 and we find that leg = 12.
