Which equation is graphed here?

Mathematics

Answer:

y+4=-3/2(x-2) is the answer

Step-by-step explanation:

Again over here just use the y=mx+c

m which is the slope is change in y over change in x which in this case is \frac{-3}{2} so which just that we can cross out the first option for the answer secondly to be able to find C just take literally any point from the graphed line, for instance we take (-2,2), just add it in the equation and solve for C

2=-\frac{3}{2}(-2)+c\\2=3+c\\0=3-2+c\\c=-1

y=-3/2-1

Now all you have to see is which of the three equations is equivalent to the one we just found

y+4=-3/2(x-2) is the answer :)

Find the equation of a line, in slope intercept form of a line that passes through the point (-5,-1) and is parallel to the line
Ludmilka [50]

Answer:

y = 1/2x + 3/2

Step-by-step explanation:

Using the equation of the line

y - y_1 = m ( x - x_1)

First find the slope of the line

-2x + 4y = 8

It must be in this form

y = mx + C

4y = 8 + 2x

divide through by 4

4y/4 = 8 + 2x / 4

y = 8 + 2x/4

Let's separate

y = 8/4 + 2x/4

y = 2 + 1/2x

y = 1/2x + 2

Therefore, our slope or m is 1/2

Using the equation of the line

y - y_1 = m ( x - x_1)

With point (-5, -1)

x_1 = -5

y_1 = -1

y - (-1) = 1/2(x - (-5)

y + 1 = 1/2( x + 5)

Opening the brackets

y + 1 = x + 5 / 2

y = x + 5/2 - 1

Lcm is 2

y = x + 5 / 2 - 1/1

y = x + 5 -2/2

y = x +3/2

We can still separate it

y = x /2 + 3/2

y = 1/2x + 3/2

The equation of the line is

y = 1/2x + 3/2

The correct answer is A

T-4t^2+2t^3<br> Please help :(
Arada [10]

Answer:

Is there a question here?

Step-by-step explanation:

t - 4t² + 2t³ =    t(1 - 4t + 2t²)

                  =  t(2t² - 4t +1)

                  ≠≠≠≠     t(2t - 1)(t -1)

        used a graphing calculator to find the roots

Maria walked 3/4 of a mile. Cody walked 6/10 of a mile. How much farther did Maria walk than Cody?
coldgirl [10]

Answer:

3/20

Step-by-step explanation:

Take the miles that Maria walked and subtract the miles that Cody walked

3/4 - 6/10

Simplify 6/10 by dividing the top and bottom by2

3/4 - 3/5

Get a common denominator of 20

3/4 *5/5 = 15/20

3/5 *4/4 =12/20

15/20 - 12/20

3/20
