B. inverse variation
c. joint variation
D. marginal variation
Answer:
A. Direct Variation
Step-by-step explanation:
I had the exact same answer on my test and I got this one correct
Answer:
Inverse Variation
Explanation:
While direct variation describes a linear relationship between two variables , inverse variation describes another kind of relationship. For two quantities with inverse variation, as one quantity increases, the other quantity decreases.
What is the value of 6/x + 2x^2, when x = 3? 08 0 11 O 14 0 20
Answer:
20
Step-by-step explanation:
substitute 3 into 6/x, thats 2
substitute 3 into 2x^2, so that would be 2(3x3) and that would be 18

Answer:
y = -3/4(x -2)
Step-by-step explanation:
You are given point (2, 0) on the new pipeline. To find the equation of it, you need to know the slope of the line on the graph. A careful look at the graph shows you the line goes through grid points that are separated by 4 units horizontally, and 3 units vertically. For a positive horizontal change, the vertical change is negative, so the slope is ...
m = rise/run = -3/4
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
For m = -3/4 and (h, k) = (2, 0), the equation is ...
y = -3/4(x -2)
_____
Additional comments
If you use the distributive property to eliminate parentheses, the equation becomes ...
y = -3/4x +3/2
The slope of the red pipeline can also be determined by considering the slope of the blue pipeline. The two marked points on that line have a horizontal separation of 3 and a vertical separation of 4. Its slope is ...
m = rise/run = 4/3
The slope of the perpendicular (red) line is the opposite reciprocal of this:
-1/m = -1/(4/3) = -3/4 . . . . as we determined from the red line's graph
In 2010, the population of a city was 168,000. From 2010 to 2015, the population grew by 7%. From 2015 to 2020, it fell by 6%. How much did the population decrease from 2015 to 2020, to the nearest 100 people?
Answer:
169,000 people
Step-by-step explanation:
increase from 2010-2015:
168000/100 = 1680 = 1%
1680 x 7 = 11,760 people
population at 2015 = 168000+11760 = 179,760
decrease from 2015-2020:
179760/100 = 1797.6 = 1%
1797.6 x 6 = 10,785.6 people
population at 2020 = 179760-10787.6 = 168,974.4 people
rounded to the nearest 100 = 169,000 people

Step-by-step explanation:
20.)
We see an increase of 10y per x, which is where we get "10x"
This means that at x = 1, y = 15, which is where we get "+ 15"
21.)
Plug in 6 for x
y = 10(6) + 15
y = 60 + 15
y = 75

11. Liza earned some money delivering newspaper .She bought a
battery for $1.95, and gave her mother $30. She bought a ring
for $7.20, and then spent half of the remaining money on a radio.
If Liza has $38.50 left, how much money did she earn delivering
newspapers?
anonh the solution set.
Answer: $116.15
Step-by-step explanation:
We first would start with the last thing, the $38.50 Lisa has left! From reading the word problem, we can tell that she had another $38.50 she spent on a radio.She spends $7.20 (ring) + $1.95 (battery) before this and gives her mom $30.
All of these are subtractions from the initial amount:
x - 1.95 - 30.00 - 7.20 - 38.50 = 38.50
x - 77.65 = 38.50
x = $116.15

- 67 minus what gives me 0
Answer:
-67
Step-by-step explanation:
-67 minus -67 = -67+67 (since two negatives make a positive) =0
Answer:
Step-by-step explanation:
For the math problem, "67 minus what equals 0?", we can make it into an algebra equation as follows:
67 - X = 0
Then, we solve for X. To solve for X, we first subtract 67 from both sides:
67 - 67 - X = 0 - 67
-X = -67
Next, you multiply each side by -1 to remove the minus from the X:
-X(-1) = -67(-1)
X = 67
Therefore, the answer to "67 minus what equals 0?" is 67 as illustrated below:
67 - 67 = 0

If m∠10 = 70, then find the m∠14 and state the angle relationship.
The measure of m∠14 is 110 degrees and the angle relationship is a supplementary angles
Let us assume that angle m∠10 and m∠14 are supplementary, this means that the sum of both angles will be 180 degrees.
Since the angles are supplementary, hence the required expression will be:
m∠10 + m∠14 = 180
Given that m∠10 = 70 degrees
70 + m∠14 = 180
m∠14 = 180 - 70
m∠14 = 110 degrees
Hence the measure of m∠14 is 110 degrees and the angle relationship is a supplementary angle.

1. Beth works at the mall for $12.75 per
hour. She works for 41 hours per day on
2 days each week. How much does she
make in 2 weeks? (before taxes)?
Answer:
$2091
Step-by-step explanation:
We know:
12.75 per hour (h)
41 hours each day twice a week: each week (41 x 2) = 82
Since it is asking for two weeks: 82 x 2 = 164 hours
164 x 12.75 = $2091

The point of intersection of the two functions is (3, 27).
The system of equations is:
f(x) = 5x + 25 - 1 = 5x + 24
g(x) = 2x - 3
To solve this system, we can use the elimination method. We can eliminate the x-term by adding the two equations together.
f(x) + g(x) = 5x + 24 + 2x - 3 = 7x + 21
Solving for x, we get:
x = 21/7 = 3
Now that we know the value of x, we can plug it back into either equation to find the value of y. Let's use the equation for f(x).
f(x) = 5x + 24
f(3) = 5(3) + 24 = 27
Therefore, the point of intersection of the two functions is (3, 27).
To the nearest tenth, the point of intersection is (3.0, 27.0).
