What is the slope-intercept equation of the line below?

Phoenix [80]

Answer:

D. y = 2x -3

Step-by-step explanation:

The equation of a line in slope-intercept form is

y = mx + b

We need to find m, the slope, and b, the y-intercept.

We can find those two numbers from the graph.

We look in the graph and see that the y-intercept, b, is -3.

Now we have y = mx - 3.

Now we look for the slope. Start at (0, -2). We need to go vertically and horizontally to the next point that is easy to read. We see that point (1, -1) is on a grid intersection making it easy to read, so we will use that point.

Go up 2 units. That is a rise of positive 2. Now go right 1 unit. That is a run of positive 1.

slope = rise/run = 2/1 = 2

m = 2, so now we have

y = 2x - 3

Answer: D. y = 2x -3

I need help please?!!!!

The multiplicative inverse of a number x is a number y such that their product xy is 1.

So, we want a number such that

$10\cdot x = 1$

Divide both sides by 10:

$x=\dfrac{1}{10}$

The length of a rectangular storage room is 3 feet longer than its width. if the area of the room is 40 square feet, find the wi

xenn [34]

Answer:

Width of rectangular storage room= 5 feet.

Step-by-step explanation:

Let x be the width of storage room.

We have been given that the length of a rectangular storage room is 3 feet longer than its width. So the length of storage room will be x+3.

We are also given that the area of the room is 40 square feet.

Since the area of a rectangle is length times width.

$\text{Area of rectangle}=\text{Length* Width}$

Let us substitute our given values in area formula.

$40=x*(x+3)$

Upon distributing x we will get,

$40=x^2+3x$

$x^2+3x-40=0$

Now let us factor out our quadratic equation using splitting the middle term.

$x^2+8x-5x-40=0$

$x(x+8)-5(x+8)=0$

$(x+8)(x-5)=0$

$x+8=0$ or $x-5=0$

$x=-8$ or $x=5$

Since width can not be negative, therefore, the width of rectangle will be 5 feet.

Let us verify our answer.

Length of rectangular storage room is 3 feet longer than its width. So length will be 5+3=8.

Given: Area=40 square feet.

5*8=40.

Hence, width of rectangular storage room is 5 feet.
