Answer:
The solution of the given two equations
( x, y) = (0,6)
Step-by-step explanation:
<u><em>Step(i)</em></u>
Given equations are
y - 2x = 6 ...(i)
y + 2x = 6 ...(ii)
Adding (i) and (ii) equations, we get
y - 2x + y +2x = 6+6
2 y = 12
y =6
<u><em>Step(ii):-</em></u>
substitute y =6 in equation (i). we get
y - 2x =6
6 - 2x =6
6-6 =2x
0 = 2 x
x = 0
The solution of the given two equations
( x, y) = (0,6)
Answer:
-2
Step-by-step explanation:
Isolate the variable y. Note the equal sign, what you do to one side, you do to the other. Divide 3 from both sides:
(3y)/3 = (15 - 6x)/3
y = (15 - 6x)/3
y = 5 - 2x
Note the equation:
y = mx + b
m = slope
b = y-intercept
x & y = the point (x , y)
Note that the slope is directly next to x. -2 is your answer.

Well we know the total of a triangle and it’s sides add up to 180 degrees
well they gave us two sides already , the side with a box - means 90 degrees .
And the other side is 41 degrees .
So we add the two side and subtract it from the total it’s supposed to be and the number we have left over is the one we are trying to find..so let’s do that .
41+90=131
180-131= (our missing side) 49
so in order the sides are :
41,49,90. in alphabetical order if they ask : C,A,B .
Hope this helps and you can understand!
