The graph represents this system of equations

Flauer [41]

Hey there! I'm happy to help!

When graphing a system of equations, the solution is the point where the two lines meet. We see that they intersect at (-2,4).

Therefore, the solution to the system of equations is (-2,4).

Have a wonderful day! :D

Determine whether each ordered pair is a solution of y = 3x-5. (2,2) (4,7) (6,13) (5,10)

cestrela7 [59]

Answer:

(4,7), (6,13), and (5,10)

Step-by-step explanation:

To determine if an ordered pair is a solution, substitute the coordinates in and check to see if they are true:

(2,2)

$y=3x-5\\(2)\stackrel{?}{=}3(2)-5\\2\stackrel{?}{=}6-5\\2\neq1$

Thus, (2,2) is not a solution.

(4,7)

$y=3x-5\\(7)\stackrel{?}{=}3(4)-5\\7\stackrel{?}{=}12-5\\7\stackrel{\checkmark}{=}7$

Thus, (4,7) is a solution.

(6,13)

$y=3x-5\\(13)\stackrel{?}{=}3(6)-5\\13\stackrel{?}{=}18-5\\13\stackrel{\checkmark}{=}13$

Thus, (6,13) is also a solution.

Lastly, (5,10)

$y=3x-5\\10\stackrel{?}{=}3(5)-5\\10\stackrel{?}{=}15-5\\10\stackrel{\checkmark}{=}10$

Thus, (5,10) is also a solution.

PLEASE HELP ME ASAP!!!! (I included the picture below with the question!!!)

Talja [164]

Answer:

$x=30^o$

Step-by-step explanation:

step 1

Find the measure of angle KNL

we know that

$m\angle KNL+m\angle LNM+m\angle ONM=180^o$ ----> by straight angle

we have

$m\angle LNM=45^o$ ---> given problem

$m\angle ONM=105^o$ ---> given problem

substitute the given values

$m\angle KNL+45^o+105^o=180^o$

$m\angle KNL+150^o=180^o$

$m\angle KNL=180^o-150^o$

$m\angle KNL=30^o$

step 2

Find the value of x

In the right triangle KNL

we know that

$m\angle KNL+m\angle NKL=90^o$ ----> by complementary angles

we have

$m\angle KNL=30^o$

$m\angle NKL=2x$

substitute

$30^o+2x=90^o$

$2x=90^o-30^o$

$2x=60^o$

$x=30^o$
