Answer:

not a function

Step-by-step explanation:

This is not a function

The input 2 goes to two different outputs

2 goes to the output of 4 and the output of 0

This makes it a relation and not a function

Is all whole numbers are integers.

All whole numbers are integers, so since 0 is a whole number, 0 is also an integer.

-2/3y-3/4=5 What is the answer i need to show my work please

vodka [1.7K]

Answer:

y= -69/8 (negative 69 over 8)

Step-by-step explanation:

First, you have to simplify both sides of the equation:

$-2/3y+ -3/4 =5$

Second, add 3/4 to both sides:

-2/3y +-3/4 + 3/4=5 +3/4

-2/3y= 23/4

Next, multiply both sides by 3/(-2) (3 over -2)

(3/-2)*(-2/3y)= (3/-2) * (23/4)

y= -69/8

Find the midpoint of the line segment joining the points (10,14) and (-7,7).

LekaFEV [45]

Answer:

(1.5, 10.5)

Step-by-step explanation:

$midpoint = \bigg( \frac{10 + ( - 7)}{2}, \: \: \frac{14 + 7}{2} \bigg) \\ \\ = \bigg( \frac{3}{2}, \: \: \frac{21}{2} \bigg) \\ \\ = = ( 1.5, \: \: 10.5 )$

In the figure, the perimeter of hexagon ABCDEF is approximately

Nikitich [7]

First solve the length of side BC, CD, EF and FA Since BC = CD = sqrt( 10^2 + 10^2) BC = CD = 14.1421
FA = EF = sqrt(10^2 + 20^2) = 23.3607
So the perimeter = 10 + 10 + 14.1421 + 14.1421 + 23.3607 = 93

The area is made up be triangle FAE, rectangle ABDE and triangle BCD
A = 0.5(20)(20) + (10)(20) + 0.5(20)(10)
A = 500 sq units
