We are given with two equations X + y = k and <span>x - y = k. to find the solution of the </span>system<span> of linear equations, we can use elimination by adding the equations to eliminate y. hence the third equation is 2x= 2k ; x = k, hence y is equal to zero. Answer is C</span>
Answer:
Step-by-step explanation:
Answer:
First one
Step-by-step explanation:
Y=1/2x+4
Answer:
1/42 is the answer because 1/7 divide by 6/1, so 7x6=42 and 1x1=1.
Answer:
C
Detailed explanation down below
Step-by-step explanation:
A bisector divides an angle in half, so we can say that:
7x - 27 = x + 57
7x = x + 84
6x = 84
x= 14
So now lets input this information
7 x 14 - 27 = m∠ LMO = 98 - 27 = 71°
14° + 57° = 71°
(Actually we didnt have to do this second equation because both angles should be equal.)
71° + 71° = 142°
So the answer is C : x=14° . m∠LMN = 142°
