Consider the relation y = 4|x + 2| + 7. What are the coordinates of the vertex?
aev [14]
To answer, we set the expression inside the absolute value symbol (II) equal to 0. That is,
                           x + 2 = 0
Then, we solve for the value of x.
                           x + 2 - 2 = 0 - 2
Hence, the value of x from the equation above is equal to -2.

Then, substitute the value of x to the equation and drop the absolute value symbol.
                       y = 4(x + 2) + 7
Substituting,
                       y = 4(-2 + 2) + 7
                             y  = 4(0) + 7
                                 y = 7

Thus, the vertex of the absolute value equation is equal to (-2,7). The answer is the last choice.

Genrish500 [490]

To find the volume of a cylinder it's

πr² x height.

So π x 10² x 10 would be the equation.

I would do it but I don't have a scientific calculator on me.

Oliga [24]

a. 4 – commutative property

b. 5 – commutative property

c. 0 – identity property

d. 4 – associative property

_____

The commutative property lets you swap the order: (a) + (b) = (b) + (a).

The associative property lets you change the grouping: (a+b)+c = a+(b+c).

The identity property lets you add 0 without changing anything: (a) +0 = (a).
