Whats times what equals negative 48 and adds up to negative 2

Answers

Answer 1

Answer:

The two figures that multiply to-48 and add up to-2 are-8 and 6.

Let's assume the two figures are x and y.

According to the problem, we've two conditions

x y = -48

x y = -2

To break this, we can rewrite the alternate equation as

x = -2- y

Now substitute this value of x in the first equation

(-2 - y) y = -48

- 2y- y² = -48

Rearranging the terms

y² + 2y- 48 = 0

Now, solving the Quadratic Equation

(y+ 8)( y- 6) = 0

Setting each factor to zero

y + 8 = 0--> y = -8

y- 6 = 0--> y = 6

So we've two possible values for y is -8 and 6.

Substituting these values back into the equation x + y = -2, we can break for x

For y = -8

x(- 8) = -2

x- 8 = -2

x = 6

For y = 6

x 6 = -2

x = -2- 6

x = -8

Thus, the two figures that multiply to-48 and add up to-2 are-8 and 6.

What two numbers multiply into 30 but adds up to negative 11

Answers

-6 and -5 both add up to -11 and multiply to 30

-5 and -6
-5*-6 = 30, since the two factors are negative the answer is positive.
-5-6 = -11, -5-6 is the same as -5 + -6 which equals -11

A telephone company charges a fixed monthly rate plus a rate per minute of usage. The company charges $135 for 100 minutes of usage and $375 for 500 minutes of usage. An equation can be written to show the relationship between the total minutes used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph of y against x?Draw a graph which joins the points (135, 100) and (375, 500) and has a slope = 0.6
Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6
Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 1.67
Draw a graph which joins the points (135, 100) and (375, 500) and has a slope = 1.67

Answers

Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6

The ordered pairs are: (100, 135) and (500, 375)

The first number is the number of minutes of usage and the second number is the charge of the month.

The slope is: ( 375 -135) / (500 - 100) = 240/400 = 0.6

Answer:

Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6

Step-by-step explanation:

Data

x: total minutes used

y: total monthly charges

x | y

100 | $135

500 | $375

That can be expressed as coordinates (x, y), so the points are (100, 135) and (500, 375).

The slope is computed with two points (x2, y2) and (x1, y1) as follows:

slope = (y2 - y1)/(x2 - x1)

Replacing with data

slope = (375 - 135)/(500 - 100) = 0.6

If the exterior angle of a regular polygon equals 120 degrees what is the shape is the polygon

Answers

It is a triangle, because the sum of the exterior angles is always 360. We need to find a natural number n, such that 360/n=120. Of course n is 3 which means there are 3 angles. Three angles means 3 sides so it is a triangle! Or triangular.
