What is the slope of the line containing the points (1,10) and (-3,10)

Mathematics
1 answer:
PIT_PIT [208]3 years ago
7 0

Answer:

0

Step-by-step explanation:

Slope is Rise over Run (y / x).

For 2 points, you would take the difference of y-coordinates and divide by the difference of x-coordinates.

(Y1 - Y2) / (X1 - X2)

Since both y-coordinates are the same (ten minus ten), your slope is zero (zero divided by anything is zero).

Solve each system of equations <br> 2x- 5y = 7<br> 3x - y = -9
Darina [25.2K]

Answer:

x = -4; y = -3

Step-by-step explanation:

2x - 5y = 7

3x - y = -9

Rewrite top equation. Multiply both sides of bottom equation by -5. Add equations. This eliminates y, and we solve for x.

         2x - 5y = 7

(+)   -15x + 5y = 45

----------------------------

      -13x         = 52

Divide both sides by -13.

x = -4

Substitute -4 for x in the first original equation and solve for y.

2x - 5y = 7

2(-4) - 5y = 7

-8 - 5y = 7

-5y = 15

y = -3

Answer: x = -4; y = -3

Rachel is a stunt driver, and she's escaping from a building that is about to explode! DDD represents Rachel's remaining distanc
skelet666 [1.2K]

Answer:

38 m/s

Step-by-step explanation:

We are given that

D represent Rachel's remaining distance( in meters ) as  a function of time is given by

D=-38t+220

We have to find the Rachel's speed.

We know that

Velocity=\frac{ds}{dt}

Substitute the values then we get

v=\frac{d(-38t+220)}{dt}=-38 m/s

Speed =\mid v\mid

Speed =\mid -38\mid =38m/s

Hence, the Rachel's speed is given by =38 m/s

Which of the following describes the sum in terms of p and q?(1 point)
snow_tiger [21]

The description of the summation expression given as p + (-q) is the sum, p + (-q), is the number located a distance, |p|, from , q, in the negative direction.

<h3>How to describe the sum in terms of p and q?</h3>

The summation expression is given as:

p + (-q)

In the above summation expression, we assume that:

p ⇒ Positive number

- q ⇒ Negative number

Having said that:

The expression -q would go in the negative direction if plotted on a number line

This means that the description of the summation expression given as p + (-q) is the sum, p + (-q), is the number located a distance, |p|, from , q, in the negative direction.

Hence, the description of the summation expression given as p + (-q) is the sum, p + (-q), is the number located a distance, |p|, from , q, in the negative direction.

candice is going to replace the top of a table with a new piece of wood. How many square feet of wood would she purchase? 8ft. ,
lukranit [14]

Answer:

She  needs to purchase  50  square feet of wood .

Step-by-step explanation:

we can find the number of square feet of wood needed to purchase by finding the area of the table

The area of the table  =  area of the triangle + area of the rectangle

Area of the triangle:

Area of the triangle  = \frac{1}{2}(base \times height)

On substituting the values from the attached figure , we get

Area of the triangle  = \frac{1}{2}(4\times  5)

Area of the triangle  = \frac{20}{2}

Area of the triangle  = 10 square feet

Area of the rectangle:

Area of the rectangle = Length X  Breadth

On substituting the values from the attached figure , we get

Area of the triangle  = 5 \times  8

Area of the triangle  =  40 square feet

Thus the area of the table  = 10 +  40 = 50  square feet
