-10 + 15xy = 20 Direct and inverse variation. constant of variation (k)
Answers
Answer:
This is an inverse variation, and the constant of variation is k = 2.
Step-by-step explanation:
Direct variation is something like:
y = k*x
Where k is the constant of variation.
So as x increases also increases y.
Inverse variation is something like:
y = k/x
k is the constant of variation.
In this case, if x increases, y decreases.
Now let's look at the equation:
-10 + 15*x*y = 20
Let's isolate y in one side of the equation:
15*x*y = 20 + 10 = 30
15*x*y = 30
y = 30/(15*x) = (30/15)/x = 2/x
y = 2/x
Then we can conclude that this is an inverse variation, with a constant of variation equal to 2.

The time it takes to travel to a destination varies inversely with the average speed. It takes two hours when the average speed is 40mph.
If the average speed changes to 80mph, what is the new travel time?
Answers
Answer:
1 hour
Step-by-step explanation:
The time it takes to travel to a destination varies inversely as its speed
T= k/S
K= TS
Time= 2 hours
Speed= 40mph
K= 2×40
= 80
Therefore if the average speed changes to 80mph then the new travel time can be calculated as follows
T= 80/80
= 1 hour
Hence the new travel time is 1 hour
The number of songs Oliver has download this year divided by 12 equals 24 what is an equation that represents this situation and how many songs has Oliver downloaded
Answers
Answer:
/12 = 24: d = 288 songs downloaded.
Hope this helps. :)
The equation that represents the given situation is x/12 = 24 and the number of songs downloaded by Oliver is 288.
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the instructions given in the question,
Assume that the number of songs downloaded by Oliver in a year is x.
Then, it is divided by 12 and equal to 24.
So, the equation will be,
x/12 = 24
And, the number of songs downloaded by him will be,
x = 24 × 12
x = 288 songs.

What are two numbers that when multiplied equal -30 and when added together equal 1?
Answers
Answer:
5 and 6
Step-by-step explanation:
-5 x 6 = -30
-5 + (6) = 1
x2 + 1x - 30 = 0
(X - 5 ) (X + 6)
To summarize, since -5 and 6 multiply to -30 and add up 1, you know that the following is true:
x2 + 1x - 30 = (X - 5 ) (X + 6)
Distribute and simplify these radicals.

Grogg skips count by 5 starting at x. The sum of the first 5 numbers he says is 65. What is the value of x?
Answers
Answer: 11
Step-by-step explanation:
Let the 5 numbers be x,x+1,x+2,x+3 and x+4.
Therefore,
x + x+1 + x+2 + x+3 + x+4 = 65
5x + 10 = 65
5x = 65 - 10
5x = 55
x = 55/5
x = 11
Therefore, the 5 numbers are 11, 12, 13, 14 and 15.
The first number is 11

In a marketing survey involving 1,000 randomly chosen people, it is found that 630 use brand P, 420 use brand Q, and 210 use both brands. How many people in the survey use brand P and not brand Q?
Answers
By Set theory, 420 many people in the survey use brand P and not brand Q.
What is Set theory?
The mathematical concept of sets, which are well-defined collections of things that are referred to as their members or elements, is known as set theory. As only sets are the subject of pure set theory, the only sets that are taken into account are those whose members are also sets.
The major reason why set theory is significant is because it offers the axioms upon which the rest of mathematics is constructed. We study sets and their characteristics in the area of mathematical logic known as set theory. A collection of items or a group of items is referred to as a set. These items are frequently referred to as elements or members of a set.
P use = 630 people
Q use = 420 people
both P&Q use ie P∩Q = 210 People
use brand P but not brand Q = P/ P∩Q
= 630 - 210
= 420
