False.

The statement "11 more than 20 percent of a number" is best expressed as 11 + 0.20n, where n represents the number.

Graph the function defined by f(x) = (x+21)
Inga [223]

Answer:

A

Step-by-step explanation:

Consider the parent function y=|x|. The graph of this function is represented as red graph in attached diagram.

Now consider the function y=|x+2|.

Remind main translations of the graph of the function y=f(x):

  • y=f(x-a) - translation a units to the right;
  • y=f(x+a) - translation a units to the left;
  • y=f(x)+a - translation a units up;
  • y=f(x)-a - translation a units down.

In your case, the graph of the function y=|x+2| is translated graph of the function y=|x| 2 units to the left (blue graph). So, correct answer is option A.

What is the area of triangle pqr on the grid? a triangle pqr is shown on a grid. the vertex p is on ordered pair 7 and 6, vertex
horsena [70]

P(7,6), Q(1,6), R(4,2)

We have PQ parallel to the x axis. We'll call that the base,

b = 7 - 1 = 6

The altitude is then the y difference h = 6 - 2 = 4

The area is \frac 1 2 bh = \frac 1 2 (6)(4) = 12

Answer: 12 square units


In general we can use the shoelace formula for the area of any polygon given coordinates. We write the points like this:

(7,6), (1,6), (4,2)

(1,6), (4,2), (7,6)

The area is then half the absolute value of the sum of the cross products:

A = \frac 1 2 | 7(6)-6(1) + 1(2)-6(4) + 4(6)-2(7) | = \frac 1 2 |24| = 12
