Step-by-step explanation:

The centroid divides the length of each median in 2:1 ratio.

The length of the part between the vertex and the centroid is twice the length between the centroid and the mid-point of the opposite side.

In case of median KM,

K is the vertex and M is the midpoint of the side JL

KT = 2× TM

5y+3 = 2(y+3)

5y+3= 2y +6

5y-2y= 6-3

3y = 3

y= 1

Danielle wants to buy a video game. At the local Big Box Store, it costs $49.95. Danielle has a coupon for 10% off at the store,

Firdavs [7]

49.95*.1= 4.99
44.96*.065= 2.92
44.96+2.92= 47.88 (the cost for first option)

44.95+4= 48.95

The first option would be cheaper.

Hope this helped you!

A-The slope is2/3 and the y-intercept is -2

USPshnik [31]

Answer:

Step-by-step explanation:

<h2>How to find the slope? </h2>

The letter <em>m</em> is usually used to refer to the slope. To calculate it, we divide the change in <em>y </em>over the change in <em>x</em>.

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In order to find this, we must find at least <em>2</em> coordinates that we know the function passes through.

In this case, we can see that the function passes through the point (3,0) and (0,-2).

$m=\frac{0-(-2)}{3-0} = \frac{2}{3}$

Now that we know that the slope is $\frac{2}{3}$ we can ignore options C and D since $\frac{3}{2} \neq \frac{2}{3}$

<h2>What is the y-intercept? </h2>

The y-intercept is the y value were the function <em>touches</em> the y axis.

In this case, we can see that the only point where the function touches the y axis (the vertical one) is -2

Let me know if you'd like me to explain something in more detail. Good luck!
