7x + 5y = 19
−7x − 2y = −16
Answer:
V = 18 pi unit ^3
Step-by-step explanation:
Volume of a cylinder is given by
V = pi r^2 h
where r is the radius and h is the height
V = pi * (3)^2 *2
V = pi *9(2)
V = 18 pi unit ^3
The volume of a cylinder is
(Pi) x (radius squared) x (height) .
Using this, you can FIND the volume of any cylinder, even when you don't know it. This one is 18 pi cubic units.
Answer:
The Slope is -5/2
Y-intercept is -25
The equation is y=(-5/2)x-25
Step-by-step explanation:
Choose a first point and a second point
Remember points are (x,y)
Use (y₂ - y₁)/(x₂ - x₁)
y-intercept: The initial value of a linear relationship, the place that a linear equation crosses the y axis, represented by the letter b, the point (0,b).
Linear Relationship -the equation that represents a straight line often represented by y=mx+b where m is the slope and b is the y-intercept.
a) y=3x+4 y=—3x+4
Answer:
They are not parallel. they would have to have the same slope to be parallel.
