Answer:

y = 3x - 5

Step-by-step explanation:

3x-y=5

-3x     -3x

-y= -3x + 5

divide each number by -1

-y/-1 = y

-3x/-1 = 3x

5/-1 = -5

The equation 3x - y = 5 can be converted to slope-intercept form as follows: y = 3x - 5

Given is an equation 3x - y = 5, we need to convert it in slope-intercept form.

To convert the equation 3x - y = 5 into slope-intercept form (y = mx + b), where "m" represents the slope and "b" represents the y-intercept, we need to isolate the variable "y" on one side of the equation.

Let's rearrange the given equation step by step:

Starting with 3x - y = 5, we can begin by moving the term involving "x" to the other side:

3x - y + y = 5 + y

Simplifying:

3x = y + 5

Now, let's isolate "y" by subtracting "y" from both sides:

3x - y = y + 5 - y

Simplifying:

3x - y = 5

To eliminate the "y" term on the left side, we can add "y" to both sides:

3x - y + y = 5 + y

Simplifying:

3x = 5 + y

Next, let's rearrange the equation to have "y" on the right side:

3x = y + 5

We can write this equation as:

y = 3x - 5

Now the equation is in slope-intercept form (y = mx + b), where the slope "m" is 3, and the y-intercept "b" is -5.

Answer:

Your slope is -1

Step-by-step explanation:

Find the change in x and the change in y and put it in change in y over change in x.

Δx = -1 - -2 = 1

Δy = -1 - 0 = -1

Slope = rise over run = Change in y over change in x =  Δy/Δx = -1/1

Therefore the slope is -1/1 which is written as just -1

Answer:

The first one

Step-by-step explanation:

Bcs when u have a closed circle is when is less or equal to, and an open circle means greater/less to.  And you have a closed bcs is less or equal to. So u look in the answers, you can already take two answers out which are the 2 and the 3 bcs they are open circle. Then x ≥ 98.6, then x is bigger than the 98.6 so the arrow would go to the right. And the answer would be first one

(How to do that in an easier way, Look at this ≥, the pointy side is aiming in the right so the arrow will go always to the right, THIS ONLY WORKS WHEN THE LETTER IS IN THE LEFT {EX. y ≤ 19, the arrow will be pointing in the left.)

Answer:

Step-by-step explanation:

To start solving this problem, you need to figure out how many Pounds( I'll use lbs.) = 5 Tons( I'll use T).

2,000 lbs. = 1 T.

X 5               X 5

10,000 lbs. = 5 T.

Now we divide. That just means that if we know that 1 person( I'll use P) = 150, we just divide 5 T( 10,000 lbs.) by 150 lbs.

10,000/150=66.6666666667

Answer:

The Answer is 2

EXPLANATION:

y(x)=2x+3

y(x+Δx)=2(x+Δx)+3

=2x+2Δx+3

Δy=y(x+Δx)−y(x)

=(2x+2Δx+3)−(2x+3)

=2Δx

⇒Δy=2Δx,  Δy/Δx =2

The rate of change in the equation of a line in slope-intercept form

y = 2x + 3 is 2.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, An equation of a line y = 2x + 3.

This is in slope-intercept y = mx + b, where 'm' is the slope.

Therefore, The rate of change in y = 2x + 3 is 2.

Michelle didn't double the height and width for the perimeter and the correct expression is:

[tex]\frac{5}{3}x+70[/tex]

Step-by-step explanation:

Given

Length = l = 5/6x+23

Width = w = 12

The perimeter of a rectangle is given by:

[tex]P = 2(l+w)[/tex]

Putting the values, we get

[tex]P = 2\{(\frac{5}{6}x+23)+12\}\\\\P = 2(\frac{5}{6}x+23+12}\\P =2(\frac{5}{6}x+35)\\P = 2*\frac{5}{6} + 2* 35\\P =\frac{5}{3}x+70[/tex]

The length and width had to be doubled for the perimeter which Michelle didn't.

Hence,
