They are of the form y = kx where k is some constant.
8x + 2y = 0 is Direct Variation because you can transform it:
8x + 2y = 0
2y = -8x
y = -4x :- here k = -4.

The median annual salary for travel agents is P300,000. If the 80th percentile for the annual salary of a travel agent is P500,000, approximately what percent of the travel agents have annual salaries less than P300,000?
Using the percentile concept, it is found that 50% of travel agents have annual salaries less than P300,000.
In a data-set, if a measure is at the xth percentile, x% of the measures are less than x.The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.In this problem, the median is of P300,000, and thus, 50% of travel agents have annual salaries less than P300,000.

Name the properties used to solve this equation:
4/3(3/4x)=4/3 * 1/4. Given
(4/3 * 3/4)x=4/3 * 1/4 a.
1x=4/3 * 1/4. b.
x=4/3 * 1/4 c.
x=1/3 4/3*1/4=1/3
We want to see the properties used to solve the given equation.
The properties used are:
Existence of the multiplicative inverse.Associative property of the multiplication.Let's write step by step and see which property we used on each step.
We start with:
[tex]\frac{4}{3} *(\frac{3}{4} *x) = \frac{4}{3} *\frac{1}{4}[/tex]
Now we use the associative property of the multiplication (says that we can multiply in any order we want) we rewrite this to:
[tex](\frac{4}{3} *\frac{3}{4} )*x = \frac{4}{3} *\frac{1}{4}[/tex]
Now we use the existence of the multiplicative inverse, this says that for a number a, there exist a number b such that:
a*b = 1
And we have that b = 1/a.
Then we apply that to the first factor to get:
[tex](\frac{4}{3} *\frac{3}{4}) *x = \frac{4}{3} *\frac{1}{4} \\\\x = \frac{4}{3} *\frac{1}{4}[/tex]
Again, using the same but with the numerator of the first factor of the right side and the denominator of the second factor of the right side we get:
[tex]x = \frac{4}{4} *\frac{1}{3} = \frac{1}{3}[/tex]
Then the properties used are:

If f(1)=6 and f(n) = F(n - 1) + 2 then find the value of f(4).
Hi there!
[tex]\large\boxed{f(4) = 12}[/tex]
We know that:
f(1) = 6
F(n) = F(n - 1) + 2 (Meaning, the next "n" is 2 added to the previous)
We can count up to f(4) using this logic:
f(2) = F(2 - 1) + 2 = F(1) + 2 = 6 + 2 = 8
f(3) = F(2) + 2 = 8 + 2 = 10
f(4) = F(3) + 2 = 10 + 2 = 12

A cube has an edge of 3 feet. The edge is increasing at the rate of 4 feet per minute. Express the volume
of the cube as a function of m, the number of minutes elapsed.
Hint: Remember that the volume of a cube is the cube (third power) of the length of a side.
Answer:
so it increases by 4 per minute
the volume of a cube is v=side^3
so the side length be 5+4m where m is the number of minutes
therefor the volume can be expressed as V(m)=(5+4m)³
Step-by-step explanation:
The volume of the cube can be expressed as a function of m, the number of minutes elapsed as V(m) = (3 + 4m)³ feet³.
What do we mean by volume?The volume of an object is the total space occupied by the object in the three-dimensional space.
How do we solve the given question?In the question, we are asked to express the volume of a cube as a function of m, the number of minutes elapsed. We are given that the initial length of the edge of the cube was 3 feet, and it increases at a rate of 4 feet per minute.
∴ We can say that the length of the edge after m minutes = 3 + 4m
As 4 feet is the increase per minute and m minutes have elapsed.
We know, that the volume of a cube is the cube of the length of the edge.
∴ The volume = (3 + 4m)³.
Hence, the function of the volume of the cube in m can be written as,
V(m) = (3 + 4m)³ feet³.

 Line v passes through point (6, 6) and is perpendicular to the graph of y = 3/4x - 11. Line w is parallel to line v and passes through point (–6, 10). Which is the equation of line w in slope-intercept form?
A: y= 3/4x+2
B: y=-3/4x+2
C: y=-4/3x+2
Answer:
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes.
Parallel lines have identical slopes
As our original line has a slope of 3/4, both lines v and w have slope of -4/3
This means that
C: y = -4/3x + 2
is the only possible option.
Let's check that the given point fits on this line.
10 = -4/3(-6) + 2
10 = 10
So our answer is correct.
