If x and y vary inversely, and x = -12 when y = 3/2, what is y when x = 2?
Answer:
y = -9
Step-by-step explanation:
If x and y vary inversely, x* y = constant
so (-12) * (3/2) = (2) * y
-18 = 2y
y = -18/2 = -9
Simplify this expression 14x + 5y - 8x - 9y
Answer:
6x - 4
Step-by-step explanation:
14x + 5y - 8x - 9y
Simplify by combining like terms:
14x - 8x + 5y - 9y
= 6x + 5y - 9y
= 6x - 4

Problem 2.2
A company bought a milling machine for $ 100,000. The company intends to use the machine for the next 5 years. The machine is expected to save the company $ 42,000 during the first year of operation. Thereafter annual savings are expected to decrease 3% each year due to maintenance costs. Assuming 4,000 hours of operation per year and that the machine will have no “Salvage Value” at the end of the 5 years, determine the equivalent savings per hour of operation at 14% compounded annually.

This data set represents the number of cups of flour used in different recipes. What is the mean of this data set? {1/2, 1/3, 2/3, 1 1/2} Enter your answer as a fraction in simplest form in the box.
Using it's concept, it is found that the mean of the data-set is of [tex]\frac{3}{4}[/tex].
What is the mean?The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.
In this problem, the 4 observations are given by:
[tex]\left{\frac{1}{2}, \frac{1}{3}, \frac{2}{3}, 1\frac{1}{2} = 1 + \frac{1}{2} = \frac{3}{2}\right}[/tex]
Hence, the mean is given as follows:
[tex]M = \frac{\frac{1}{2} + \frac{1}{3} + \frac{2}{3} + \frac{3}{2}}{4} = \frac{\frac{3 + 2 + 4 + 9}{6}}{4} = \frac{18}{24} = \frac{3}{4}[/tex]
The mean of the data-set is of [tex]\frac{3}{4}[/tex].

Find the slope and the y-intercept of the line.
3x+2y=7
Write your answers in simplest form.
Step-by-step explanation:
Make 3x+2y=7 to slope intercept form. y = mx + b
So subtract 3x from both sides to get 2y= -3x + 7
Then divide by 2 on both sides to get y = -3x/2 + 7/2
The slope is -3/2 and the y-intercept is 7/2

What is the equation in point slope form for a linear function with a slope of m= -4 that passes through the pot
(2, - 7)?
Answer:
Step-by-step explanation:
m = -4 ; (x₁ , y₁) = (2, -7)
Point slope form: y - y₁ = m(x - x₁)
y - [-7] = (-4)(x - 2)
y + 7 =(-4)(x - 2)
