Answer:
28 degrees maybe
Step-by-step explanation:
I dont have a picture but if it's a supplementary line than it has to be equal to 180
The solution of the system of equation is (-2 ,2).
<h3>What is a System of Equation ?</h3>
A system of equation is defined as the equation that have a common solution.
The system of equation is
x+y = 0
y = 2x+6
2x-y = -6
3x = -6
x = -2
y = 2
The graph of both the equations are plotted and the common point is the solution of the equations.
The solution of the system of equation is (-2 ,2).

$75
Because 450/3=150 and 150-75 is 75
Correct composition of ( f o g)(1) is option A i.e. (ƒ ∘ g)(1) = 49
<h3>What are functions ?</h3>
- In mathematics, a function from a set X to a set Y assigns exactly one element of Y to each element of X.
- The sets X and Y are referred to together as the function's domain and codomain, respectively.
- A function connects an input with an output.
- It works like a machine, having an input and an output.
- Furthermore, the input and output are linked in some way.
<h3>Calculation </h3>
f(x) = 5
– x + 1
g(x) = -3x
a) ( f o g )(1) = 49
f(g(1)) = 49
5 * -
- (-3) + 1 = 45 +3+1 = 49
it is true
all the other options are not equal to the given answer .
