Answer: Angles are supplementary if and only if their sum is 180° is true.
Step-by-step explanation:
Test by making both parts negative: Angles are not supplementary if and only if their sum is not 180° This is also true.
Answer:
-1/2
Step-by-step explanation:
Slope is defined as change in x/change in y.
The x changed by 1/8-(-1/4)=3/8 and the y changed by -4-(-1/4)=(-3/4).
Now, divide the 2 fractions:
(-3/4)/3/8 = -3/4*8/3 = -4/8 = -1/2
Answer:
The expression is not factorable with rational numbers
Step-by-step explanation:
An equation is formed of two equal expressions. The solution of the equation is 41.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution of the equation,
x + 21 = 62
x = 62 - 21
x = 41
Hence, the solution of the equation is 41.

X=6
Explanation: 6(x-4)-4=8
Multiply 6 by x and 4 to get (6x-24)-4=8
-24-4=-28, therefore, 6x-28=8
Add 28 to each side +28 +28
..To get 6x=36. Divide each side by 6...
