Answer:
78°
Step-by-step explanation:
Angles on a straight line = 180°
AD is the straight line
Angle BFA = 48
Angle CFD = 54
54 + 48 = 102
180 - 102 = 78
Therefore, Angle BFC = 78°
Lev was incorrect because both sides of equation are not equal when putting (9,4) in the equation.
Step-by-step explanation:
Given equation is:
We have to check if the point (9,4) is the solution to the equation or not
So putting x=9 and y = 4 in equation
He was wrong when he said that (9,4) is the solution to the equation because both the sides of the equation are not equal when putting the point in the equation.
In order for a point to be the solution of an equation, both sides of the equation should be equal after putting the point.
Lev was incorrect because both sides of equation are not equal when putting (9,4) in the equation.

Answer: the first graph
Reasoning: When a graph is going left to right it is a decay while when it’s going right to left it is an increase... think of linear equations where if it is going from left to right the slope is negative, it’s the same for the exponential decay and increase.
