(f-g) (x) is equal to positive 2
Answer:
9
Step-by-step explanation:
In the notation of a function f(x) = x+8, for input x=1 the output would be 9. And (1,9) would be an (x,y) pair that fits the function.
The answer is $1.6
Step 1. Find the mean of all values (X = ?).
Step 2. Find the distance of all values from the mean (d1, d2, d3, d4, d5).
Step 3. Find the mean of distances (D).
x1 = $12
x2 = $9
x3 = $6
X4 = $8
x5 = $10
Step 1.
X = (x1 + x2 + x3 + x4 + x5)/5
= (12 + 9 + 6 + 8 + 10)/5
= 45/5
= $9
Step 2.
d1 = 12 - 9 = 3
d2 = 9 - 9 = 0
d3 = 9 - 6 = 3
d4 = 9 - 8 = 1
d5 = 10 - 9 = 1
Step 3.
D = (d1 + d2 + d3 + d4 + d5)/5
= (3 + 0 + 3 + 1 + 1)/5
= 8/5
= $1.6
Answer.
x minus y => x - y
x subtracted from y => y - x
six less than a number is y => y = x - 6
six times a number equals y => 6x = y
y divided by x => y ÷ x
the sum of x and y => x + y = 6
the product of two numbers => xy
x divided by y => x ÷ y
product of two numbers is six => xy = 6
the sum of two numbers is six => x + y = 6
