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)

The answer is 6 and -5

-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.

Answer:

Diagonals of a parallelogram bisect each other

Given vertices:

(-2,-1), (1,3), (6,3), (3,-1)

Plot the points.

We see the diagonals are:

(-2,-1) (6,3)  and (1,3), (3,-1)

The midpoint of any diagonal is the intersection of the diagonals.

Use midpoint formula to find the coordinates:

x = (x₁ + x₂)/2 = (-2 + 6)/2 = 4/2 = 2y = (y₁ + y₂)/2 = (-1 + 3)/2 = 2/2 = 1

The point is (2, 1)

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

Distribute and simplify these radicals.

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.

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
