PLZ I'M BEING TIMED Which equation could have been used to create this table?

Talja [164]

Answer:

y=6x

Step-by-step explanation:

Let us assume the table is the one shown in the attachment.

We can observe the following pattern from the table:

$12=6*2$

$24=6*4$

$36=6*6$

$60=6*10$

$76=6*12$

Hence in general

$y=6*x$

Therefore the equation that could have been used to create this table is

$y=6x$

Find three consecutive integers such that that product of the first and third is one

Tema [17]

Answer:

n = the first

n + 1 = the 2nd

n + 2 = the 3rd

n(n + 2) - (n + 1) = 10(n + 2) + 1

n2 + 2n - n - 1 = 10n + 20 + 1

n2 - 9n - 22 = 0

(n - 11)(n + 2) = 0

If two factors = 0, at least one must = 0.

n - 11 = 0

n = 11

11,12,13

n + 2 = 0

n = -2
