The answer will be: F= 5*3 = 15
Answer:
f^-1 (x)=x/3
Step-by-step explanation:
y=3x
x=3y
y=x/3
Answer:
The equation is not linear
Step-by-step explanation:
You are given the equation

Express y in terms of x:

The linear function must of form

where m and b are real numbers.
Your function is not of this form, so this is not a linear function.
Answer:
(-3, 13)
Step-by-step explanation:
Coordinate of A is (7,5)
4 units to the left means (7-4, 5) --> (3,5)
8 units up means (3, 5+8) --> (3,13)
Reflected across the y-axis means that the sign of whatever x coordinate you have now will be reversed.
So (-3,13)
A/2=b/3
b/a
a=2/3b
b=3/2a
4b/9a
