Answer:

N=6

Step-by-step explanation:

First, you move the -15 to the other side along with -9 so you have like terms in the same side. This will make it easier for you to solve for the answer.

To move -15 to the other side, you simply move it over next to -9 and change the sign. Since it was -15, it becomes positive 15. So the equation should look like n= -9 + 15.

Now, the equation looks much easier, right? All you need to do to find the answer is do -9+15, which equals 6. That's it!

Answer:

  (c)  162 cm

Step-by-step explanation:

The centroid divides a median into parts with the ratio 1:2, so RL:LD = 1:2. Then RL:RD = 1:(1+2), and RD = 3RL.

  RD = 3·54 cm

  RD = 162 cm

Triangles ABC and RST are similar. Find ST.
Bezzdna [24]

Set up;

(15^2)(CB) = (7.5^2)/(ST)

(15^2)/(5) = (7.5^2)/(ST)

Cross-multiply to find ST.

Y=-4x+4
attashe74 [19]
Steps:
1. Substitute the y in y=4x + 4 and put
X-6=-4x+4
2. Add 4x to both sides
3. 5x-6=4
4. Add 6 to both sides
5. 5x=10
6. Divide by 5 on both sides
7. X=2
8. Now to find the y, you substitute 2 for x in the problem y=x-6
9. Y=2-6
10. Y=-4
11. Your answer is
(2, -4)

A line passes through the point (-2, 7) and has a slope of -5.
trapecia [35]

Answer:

a= -1

B

Step-by-step explanation:

My opinion:

the slope m = (y2 - y1) / (x2 - x1)

slope m is -5

y2 is 7

y1 is 2

x2 is -2

x1 is a

so the equation will be

-5 = (7 - 2) / (-2 -a )

10 + 5a = 5

5a = -5

a = -1

Then you can plug the value a = -1 into the equation of the slope m to double check it.
