This is a straight line. We only need 2 points to graph a straight line.

Let x = 0

y = -(0) - 1

y = -1

Our first point is (0,-1).

Let x = 1

y = -(1) - 1

y = -2

Our second point is (1,-2).

See attachment for graph.

Describe the possible values for x and y when ∣x − y ∣ > 0. What does it mean when ∣x − y ∣ = 0? Can ∣x − y ∣ < 0? Explain

Vilka [71]

The possible values for | x-y | > 0 is any number above 0. x must be greater than y. When | x-y | = 0, That means that x and y are equal to each other. | x-y | can not be less than 0, but it can equal 0.

Hope that this helped!

Okay, I'm going to be adding more but what is 4/10 x 3?

Marat540 [252]

Answer:

6/5 or 1 1/5

6/5 is an improper fraction, so I didnt know if youd need an improper one or a proper one. They both are the same thing though :)

Step-by-step explanation:

4/10*3

They both need to be a fraction, and any number over 1 = that number. So,

4/10*3/1

4*3=12

10*1=10

12/10

Then, you have to simplify the fraction.

6/5 (bc 2 goes into 12 6 times and 2 goes into 10 5 times)

or 1 2/10= 1 1/5

Hope this helps. Plz give brainliest. Also, plz sub to Kgirl633 on yt.

Please help don’t understand

Morgarella [4.7K]

Answer:

r = 4

Step-by-step explanation:

If we clearly observe a point and the slope of the line are given.

Point=(5, -6) slope= -5

We know that the equation of the line having slope m and passing through point ( $x_{1} , y_{1}$ ) is

$y-y_{1}=m(x-x_{1})$

Now the equation of the line is $y-(-6)=(-5)*(x-5)$

$y+6=-5x+25$

$5x+y=19$

Now given that (3,r) lies on this line

$5*3+r=19$

r = 4

In the diagram below, line segment AB has endpoints at A(-2,-6) and B (3,-1). Give the coordinates of line segment A'B' after a

love history [14]

Answer:

A’ (6,-2)

B’ (1,3)

Step-by-step explanation:

Here, we want to give the coordinates after a counterclockwise rotation of 90 degrees

Given a point with coordinates (x,y)

A counterclockwise rotation at 90 degrees to the origin will yield the coordinates (-y,x)

So A (-2,-6) will be A’ (6,-2) while B (3,-1) will be B’ (1,3)

The width of a rectangle is increasing at a rate of 5 inches per second and its length is increasing at the rate of 9 inches per

Marianna [84]

Answer:

The area of rectangle is changing at the rate of 33 square inches per second.

Step-by-step explanation:

We are given the following information:

Let W be the width of the rectangle and L be the length of rectangle.

Rate of change of width = $\frac{dW}{dt} = 5\text{ inches per second}$

Rate of change of length = $\frac{dL}{dt} = 9\text{ inches per second}$

We have to find rate of change of area at W = 2 and L = 3.

Rate of change of area = $\frac{dA}{dt}$

Area of rectangle = Length × Width

$\frac{dA}{dt} = \frac{d(LW)}{dt} = L\frac{dW}{dt} + W\frac{dL}{dt}$

Putting the values, we get

$\frac{dA}{dt} = 3(5) + 2(9) = 33\text{ square inches per second}$

The area of rectangle is changing at the rate of 33 square inches per second.
