Answer:
y = - 3x - 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute (- 4, 6) into the partial equation
6 = 12 + c ⇒ c = 6 - 12 = - 6
y = - 3x - 6 ← equation of line
The best way for him to check his answer would be to simply plug in the value found for x into the equation.
4(2) - 6 = 2
8 - 6 = 2
2 = 2
41.803 rounded to the nearest whole number is 42
Answer:
C
Step-by-step explanation:
Cross section means looking at an object from where it was cut. If you imagine looking at the cube with the cylinder cut from it's center from where it was cut at, you would see that it basically resembles a square with a indent in the middle. Hopefully this makes sense to you.
