Answer:
is equivalent to 
Step-by-step explanation:
Using exponent rules:

Given the expression:

⇒
Apply the exponent rule, we have;

Therefore, the given expression
is equivalent to 
Question 1= would equal 63 but why is there no 63?(did you type the answers right? or the angles right?
47+70=117
180-117=63
question 2 would be 36
54+90=144
180-144=36
We have been given a system of equations.
and
. We are asked to find the solution of our given system of equations.
The solution of our given system of equations will be the point, where both lines will intersect.
To find intersection point, we will equate both equations as:





Now we will substitute
in equation
and solve for y.

Therefore, the point
is the solution of our given system of equations.
We can verify our answer by graphing both equations.
-2x-4y = 2
-2x-4y+4y = 2+4y
-2x=4y+2
Divided by 2:
-2x/-2 = 4y +2/ -2
Answer: x=-2y-1
3x +4y =8
3x + 4y = -4y = 8+-4y
3x= -4y +8
Divided by 3
3x/3 = -4y + 8/3
x=-4/3y + 8/3
