Answer:

The ordered pairs of A and C are not functions

Step-by-step explanation:

To determine if the ordered pairs are a function you look at the x values to see if they repeat. You don't want one input(x values) to lead to two outputs(y values). This would mean that you are never sure which output you will get.

In the answer A the x value "2" repeats, in the answer C the x value "1" repeats thus not making them functions.

What is the solution to the equation 2(4-3x)+5(2x-3)= 20-5X2

Alja [10]

Answer:

7-16x=10. I'm sorry I'm not good at math but it never hurts try, right?

Step-by-step explanation:

Multiply the parentheses first which would give you

8-6x+10x-15.

Next add 6x+10x which would give you

8-16x-15.

Then subtract 8-15 which would give you

7-16x=20-5x2. Then work the problem from there.

7-16x=20-10.

7-16x=10.

Is the set of numbers one 1,5,25 and 125 a geometric sequence

Strike441 [17]

Short answer: Yes.
Each member of the sequence is multiplied by 5 to get to the next member of the sequence.

Find the general equation.
tn = a*5^(n - 1)

Example
t4 = 1*5^(4 - 1)
t4 = 1*5^3
t4 = 125 just as the sequence shows.

t5 = 1^5^4
t5 = 625 Any member of the sequence can be found this way.
