Hi!

<h3>To do this, put the values in the equation. </h3>

-2 * 2 + 4 * 5 = -16

<h3>Solve</h3>

-4 + 20 = -16

<h2>(2,5) is not a solution of -2x+4y=-16</h2>

Hope this helps! :)

This is false when u fill in for x you get the answer -3 and it should be five and when you fill in for why you get the answer 18 and it should be 2 which makes the statement incorrect

Given the system of inequalities below: -3x - y < 12 2x + 3y ≥ 9 Give the coordinates of three points that are members of the

earnstyle [38]

Answer:

The coordinates of the points that are members of the solution set

(-3,7), (0,4) and (2,3)

Step-by-step explanation:

we have

$-3x-y< 12$ ----> inequality A

The solution of the inequality A is the shaded area above the dashed line

$2x+3y\geq 9$ ----> inequality B

The solution of the inequality B is the shaded area above the solid line

The solution of the system of inequalities is the shaded area between the dashed line and the solid line

see the attached figure

Remember that,

If a ordered pair is a solution of the system of inequalities, then the ordered pair must be in the shaded area of the solution

Plot the points

(-3, 7), (-3, -7), (3,-7), (-4,-0), (0,-4), (0,4), (2,3), (-2,3), (2,-3)

therefore

The coordinates of the points that are members of the solution set

(-3,7), (0,4) and (2,3)

decide whether enough information is given to prove that the triangle is congruent using the SAS congruence theorem. if so, writ

Paladinen [302]

Answer:

Step-by-step explanation:

Given:

ΔCAD and ΔCBD

∠A ≅∠B (Angle)

AD ≅BD (Side)

From the graph we see that

CD≅CD (Side)

because of reflexive propriety ( a line segment is congruent with itself)

If you put in order those congruencies we have SSA witch does NOT prove congruence.

we not use SAS because the angle between the sides is not congruent

Least to greatest !?

Bad White [126]

The lengths are $\frac{5}{6} \frac{5}{12} and \frac{1}{3}$
finding the LCM we get
$\frac{10,5,4}{12}$
arranging them
$\frac{1}{3} \frac{5}{12} and \frac{5}{6}$

If the measure of angle a is 112 the measure of angle b is 112. True or false.

den301095 [7]

Answer:

False

Step-by-step explanation:

Angles a and b add to 180° (linear pair), so angle b is 68°.
