A function can only have one input to one output. These have more than one output for each input. You can also do the vertical line test, if it touches more than two points at the same time while going horizontally across, it is not a function.

Ashley, Milan, and Carlos sent a total of 131 text messages over their cell phones during the weekend. Carlos sent 7 times as ma

nordsb [41]

Answer:

Ashley= 15

Milan= 11

Carlos= 105

Step-by-step explanation:

Let, A, M and C denotes Ashley, Milan and Carlos respectively.

A+M+C= 131 (according to the question)

Here,

C= 7A

A= M+ 4

So, M= A - 4

Now,

A+M+C = 131

or, A+ A-4+ 7A = 131 (putting the values)

or, 9A - 4 = 131 (adding like terms i.e. A + A + 7A)

or, 9A = 131 + 4

or, 9A = 135

or, A = 135 / 9

So, A = 15

C= 7A = 7×15= 105

M= A-4 = 15 - 4 = 11

The value of an investment increased from 750 to 795 by which percentage did the value of the investment increase

So what you do is take the old value - the new value/the old value so the equation is 795 - 750 / 750 so the answer is 6%
