Answer:
3x - 6
Step-by-step explanation:
To evaluate f(2x) and f(x + 2) substitute x = 2x and x = x + 2 into f(x)
f(2x) = 3(2x) - 2 = 6x - 2
f(x + 2) = 3(x + 2) - 2 = 3x + 6 - 2 = 3x + 4
Thus
f(2x) - f(x + 2)
= 6x - 2 - (3x + 4)
= 6x - 2 - 3x - 4
= 3x - 6
Answer:
x^b+2/b^b+2
Step-by-step explanation:
substitute the value of the variable into the equation and simplify
Enlargement: Anything higher than 2
Example: (2,2)
scale factor:4
Multiply coordinate by 4
New coordinate: (8,8)
Reduction: Anything less than 1
Example: (4,4)
Scale factor: 1/2
Divide coordinate by 1/2
New coordinate: (2,2)
HOPE THIS HELPS YOU! ^_^
To solve this we'll put the question in this format: x% of y things = z things
We have the percent so we'll put in 60 for x.
Now the total number of balls will be considered y since we have the number of red balls but not blue ones. so we end up having..
60% of y balls = 720 balls
Of is another word for multiplication, therefore:
60/100*y=720
Solve for y
y=1200
So we have 1200 balls
