Answer:
The fourth option with x values of -3,-2,4 and 7 is a function of x.
Step-by-step explanation:
This is due to it having only one of each x value.
On the other tables, they have multiple values for an x value. This means that it is not a function
I know that the second one the fourth one and the fifth one are arithmetic but I’m not sure about the others I think there are only three but don’t count me on it
Answer:
5 times
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
First you need to multiply both sides of the equation by -6/5
-6/5 × (-5/6x) = -6/5 × -10/3
Then you need to calculate and reduce. First, you'll reduce the numbers with the greatest common divisor, 6.
1/5 × 5x = -6/5 × (-10/3)
then reduce the greatest common divisor, 5
x = -6/5 × (-10/3)
Then multiply (multiplying two negatives equals a positive)
x = 6/5 × 10/3
reduce the greatest common divisor, 3
x = 2/5 × 10
reduce the greatest common divisor, 6
x = 2 × 2
x = 4
(i know this is confusing, sorry)
Answer:
5
Step-by-step explanation:
x × 4 = x + 15
4x = x + 15
-x -x
3x= 15
