Answer:
D) y = −2/5x
Step-by-step explanation:
In the equation for a line ...
y = mx +b
the constant 'b' is the y-intercept of the line. The y-intercept is the value of y when x = 0.
The point (0, 0) tells you the y-intercept is 0, or b=0. That reduces the equation to the form ...
y = mx
The value of m is most easily found if you have a point where x=1. In that case, ...
y = 1m
y = m
In the given list of points, there is one that is helpful here: (1, -0.4). That is, the equation for the given points is ...
y = -0.4x
The answer choices are given as fractions, so you must convert -0.4 to the fraction -2/5.
y = -2/5x . . . . describes the given points
C. an electron microscope, safety goggles, and eyeglasses
The point in between is (1,2)
Answer:
We are looking for the amount of wax it will take to fill up that size candle mold to make that candle. That means that we are looking for the volume of wax, and the shape is a cylinder. The volume formula for a cylinder is
For us, that will look like this:
which translates to
V = 3.14(9)(5) which gives us a volume of 141.3 cubic inches. Rounding to the nearest cubic inch is simply 141 cubic inches of wax.

Answer:
49.5 mi
Step-by-step explanation:
Area of a triangle is A = (height) X (base) / 2
So if you plug in the numbers you get:
806.9 = (32.6) X (base) / 2
1613.8 = (32.6) X (base)
1613.8 / 32.6 = base
base = 49.5 mi
