Answer:
a=1 and b=13
do you need the working out?
Answer:

Step-by-step explanation:
In order to find x with the equation
, we can play with the equation until we have x isolated on one side of the equation.
Add 13 to both sides:

Hope this helped!
Answer:
B) -3
Step-by-step explanation:
The sum of the three angles of any triangle is equal to 180 degrees.
180-50-87 = 43.
43 = x+46
x = 43-46
x = -3
The functions could represent g(x) is B. 
<h3>How can the function be determined?</h3>
Using the general equation 
The g(x) has intercept of y=-2,
Then the y-intercept of f(x) is at y=3
If we find the difference between both y-intercepts, we have
( -2 -3) = -5
Then b=-5
Hence,
is correct.
