Answer:
Inverse of a function
Step-by-step explanation:
If the x- and y-values in each pair of a set of ordered pairs are interchanged, the resulting set of ordered pairs is known as the inverse of a function.
For example, given the following function:
y = 2x
If x=0 → y= 0
If x=1 → y= 2
If x=2 → y= 4
Now, if we find the inverse of the function:
y = 2x → x = 2y → y = x/2
Now:
If x=0 → y= 0
If x=2 → y= 1
If x=4 → y= 2
Comparing both cases, you will notice that the ordered pairs are effectively interchanged.
Answer
12x+40
Step-by-step explanation:
when distributing, you have to multiply all numbers in the parentheses by the variable outside the parentheses
Supplementary = angles add up to 180
Measure = 20 less
Labelled as x + (x - 20) = 180
Solve.
x + (x - 20) = 180
2x = 200
/2 /2
x = 100
Angle 1: Angle 2:
x - 20 x
100 - 20 100
80
Therefore the angle is 80 degrees.
Proof: 80 + 100 = 180 (supplementary)
100 - 80 = 20 (80 is less than supplement (100)
Hope I helped :))))
400
because you need to divide 36/0.09=400
