Answer:
y = 5x - 56
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
Here m = 5, thus
y = 5x + c ← is the partial equation of the line
To find c substitute (8, - 16) into the partial equation
- 16 = 40 + c ⇒ c = - 16 - 40 = - 56
y = 5x - 56 ← equation of line
Answer:

31.7
Answer:
4
Step-by-step explanation:
To answer this question, you will use the formula given to find the volume of concrete.
V = 3.14 x 0.6^2 x 30
V = 33.912m³
The volume of concrete is approximately 33.912 m³.
Supplementary: Angles that add up to 180 degrees.
This means that angle 1 and angle 2 add up to 180 degrees. You can put them into an algebraic problem like I have in this (the image I have added), and solve for what x is. That is the key to finding out what angle 1 equals!
Once you have found x you can plug it into the equation you have for angles 1 and 2 to find if they equal 180.
Hope this helps!
