Answer:

<em>NI = 3 cm</em>

Step-by-step explanation:

The side splitting theorem allows you to set up this proportion.

\dfrac{AT}{AR} = \dfrac{TN}{NI}

\dfrac{8}{2} = \dfrac{12}{NI}

Cross multiply.

8NI = 2 *12

8NI = 24

NI = 3

guapka [62]
Coordinates of mid point=(x1+x2/2 , y1+y2/2)
=(5+7/2 , 13+5/2)
=(12/2 , 18/2)
=(6 , 9)
Use this formula to get coordinates of mid point
here the coordinates of mid point are (6,9)

Graph the system of equations on your graph paper to answer the question. {y=−3x+9y=−x−5 What is the solution for the system of
marysya [2.9K]

y=−3x+9 slope of this equation is -3 and y-intercept is 9

Plot the y -intercept first which is 9 and mark the points using the slope which is -3. Join the points. So blue line in the graph is y = -3x+9

y=−x−5 slope of this equation is -1 and y intercept is -5

Plot the y -intercept first which is -5 and mark the points using the slope which is -1 . Join the points. So pink line in the graph is y = -x-5

The intersection point of these two lines gives you the solution.

The coordinates of point of intersection (7,-12)

How do you factor 5x^2b^2 + 14xb^2 -3b^2
Monica [59]

Answer:

5b^2(x-0.2)(x+3)

Step-by-step explanation:

The first thing that I noticed was that all of the terms had a common factor of b^2. You can therefore factor that out first:

5x^2b^2 + 14xb^2 -3b^2= \\\\b^2(5x^2+14x-3)

Now, you have a quadratic equation inside the parentheses. Factoring, you find that the roots are -0.2 and 3, meaning that you can further factor this expression to be:

5b^2(x-0.2)(x+3)

Hope this helps!
