Substitution to solve the linear system
STALIN [3.7K]

y=4x+2. eq1

y=5x. eq2

4x=2-y

x=(2-y) /4

substitute in equation 2

y=5(2-y) /2

y=(10-5y)/2

4y=10-5y

9y=10

y=10/9

substitute in equation 2 or 1

substituting in equation 2

10/9=5x

x=10/45

x=10/45 y=10/9

you can verify it also.

Please Help ASAP I dont understand this <br><br>​
antiseptic1488 [7]

To find m<3, we can use the angle sum of triangles, in which the addition all angles in a triangle must be equal to 180°.

In this case:

m<3 +52°+29° = 180°

m<3 + 81° = 180°

m<3 = 180°-81°

m<3 = 99°

To find m<4, we can use adjacent angles on a straight line, where the addition of angles on a straight line must be 180°.

In this case:

m<4 + 99° = 180°

m<4 = 180°-99°

m<4 = 81°

Therefore m<3 is 99° while m<4 is 81°.

Hope it helps!
