What is the value of g(3) when g(2) = 21–2?

Evgen [1.6K]

Answer:

g(3)=31.5-3

Step-by-step explanation:

first you want to find g(1) or g(x). all you have to do for this is divide every number by two, since 2/2 is 1.

g(1)=10.5-1

now to find g(30 you just multiply it all by 3.

g(3)=(10.5-1)*3

g(3)=31.5-3.

The quadrilateral shown is a rectangle. What is the measure of CE?

aalyn [17]

Answer:

|CE|=2

Step-by-step explanation:

The quadrilateral is shown in the attachment

Recall that the diagonals of a rectangle are congruent.

This implies that:

|AC|=|BD|

We substitute the expressions to get:

$2x-6=5x-21$

This is now a linear equation in one variable.

Group similar terms to get:

$-6+21=5x-2x$

Simplify to get:

15=3x

Divide both sides by 3 to get:

$5=x$

Recall again that the diagonals of a quadrilateral bisect each other.

$|CE|=\frac{1}{2}|AC|$

$|CE|=\frac{1}{2}|2x-6|$

Plug x=5

$|CE|=\frac{1}{2}|2*5-6| =10-6=\frac{1}{2}*4=2$
