Answer:

Step-by-step explanation:

Graph the absolute value function y = |x|. This is v-shaped and opens up.

Now translate the entire graph 2 units to the left. You will then have the graph of y=|x+2|.

Irect Variation

Anit [1.1K]

For this case we have to by definition, if "y" varies directly with "x" then it is true that:

$y = kx$

Where:

k: Is the constant of proportionality

We find the constant "k" according to the given data:

$14 = k (-4)\\k = - \frac {14} {4} = -\frac {7} {2}$

Thus, the constant of proportionality is $- \frac {7} {2}.$

Now, we find the value of "y" when $x = -6:$

$y = - \frac {7} {2} (- 6)\\y = \frac {42} {2}\\y = 21$

Thus, when $x = -6$ , the value of y is 21.

ANswer:

$y = 21$

Answer:

D

Step-by-step explanation:

$a_{n}=\frac{(n+3)!}{(n+3}=\frac{(n+3)(n+2)!}{n+3}=(n+2)!\\a_{1}=(1+2)!=3!=3*2*1=6\\a_{2}=(2+2)!=4!=4*3*2*1=24\\a_{3}=(3+2)=5!=5*4!=5*24=120\\a_{4}=(4=2)!=6!=6*5!=120*6=720\\a_{5}=(5+2)=7!=7*6!=720*7=5040$
