D; 1 and 6 are being added together first then divided by 7, so need the parentheses around 1 and 6
Equation of a line through two points is given by (y - y1) = ((y2 - y1)/(x2 - x1))(x - x1)
y - 5 = ((3 - 5)/(1 - (-1)))(x - (-1))
y - 5 = (-2/2)(x + 1)
(y - 5) = -(x + 1) = -x - 1
x + y = -1 + 5
x + y = 4
Answer:
One-third of the volume
Step-by-step explanation:
Volume of cylinder = πr²h
Volume of cone = (1/3)πr²h
Answer:
x = -6
Step-by-step explanation:
Slope is rise over run (change in y divided by change in x), and to have an undefined slope change in x must be zero. The line x = -6 is a vertical line that passes through the point (-6,8).
