Answer:

(1, 4)

Step-by-step explanation:

5x-2y=-3 -2x-y=-6  =>

5x-2y=-3

-2x-y=-6   Multiply all three terms by -2:  4x + 2y = 12

Then we have:

5x-2y=-3

4x + 2y = 12

---------------------

 9x = 9 and so x = 1.  Then, using -2x - y = -6,  and substituting 1 for x:

-2(1) - y = -6, or

2 + y = 6, or

y = 4

Then the solution is (1, 4)

suppose someone tells you that she has a triangle with sides having lengths 2.6, 8.1 and 8.6 is this a right triangle? why or wh
yawa3891 [41]
By the converse of the Pythagorean Theorem, if 8.6 ^2 = 8.1 ^2 + 2.6 ^2 , then the triangle is right. 73.96 is not equal to 72.37 so the triangle is not a right triangle.

8.6^2 is greater than (8.1^2 + 2.6^2) which means that the triangle is obtuse.
The obtuse angle is opposite the 8.6 side.

On the number line above, points J, K, L, and M are integers, and JK:KL:KM = 2:1:3. What is the value of KM? number line shown b
Rama09 [41]

Answer:

<h2>F. 12</h2>

Step-by-step explanation:

The distance between A and M i.e JM = M - J = 5-(-19)

JM = 5+19

JM = 24

If JK:KL:KM = 2:1:3

The total ratio = 2+1+3

Total ratio = 6

Dividing each length based on ratio

length JK = 2/6 * JM

JK = 1/3 * 24

JK = 8

length KL = 1/6 * JM

KL = 1/6 * 24

KL = 4

length KM = 3/6 * JM

KM = 1/2 * 24

KM = 12

<em>Hence the value of KM is 12</em>
