Resolving a function of any nature means determining your zeros or raizes.
The zeros of a function occur when the function is null.
Then:
f(x) = 3x - 2
To determine the root
f(x) = 0 = 3x - 2
3x = 2
x = 2/3 Final result
Answer:
C, 200 miles in 4 hours
Step-by-step explanation:
You divide 200 by 4, then you get 50. 50 miles in 1 hour!
Answer:
x = - 1
Step-by-step explanation:
Given
4x = x^2 - 5 Transfer 4x to the right side.
Solution
x^2 - 4x - 5 = 0 Factor
(x - 5)(x + 1)
You want the negative solution. That means that the middle sign must be plus.
x + 1 = 0 Subtract 10 from both sides
x = - 1 Ten on the left disappears by the subtraction process.
Is that correct?
4x = x^2 - 5
x = - 10
4*(-1) = (-1)^2 - 5
-4 = ? 1 - 5
-4 = - 4
and it does work.
Answer:
So it will take 6 minutes to ring up 72 items.
Step-by-step explanation:
Well this seems pretty simple just have to reads the question and know what to find.
So what we know :
A cashier can ring up 12 items per minute
So :
1 minute = 12 Minutes
And we have to find :
How long for 72 items
So since we know he can do 12 in a minute and it is asking how many minutes it will take for 72 we can divide.
So :
72 / 12
=
6
So it will take 6 minutes to ring up 72 items.
I hope this helps!

He was 4 foot. With this I just took .5 and multiplyed it by 4, then subtracted it from 6. Hope this can help! Feel free to message me if you have anymore questions!
