Does there exist a function that is not a relation

Mathematics

No, a function is always a relation. A relation may not always a function but the vice versa is true.

It's like the relationship between a rectangle and a square. A rectangle has 4 right angles and 2 sets of congruent sides while a square has 4 right angles and all sides are congruent. Which means that a rectangle is a square, but a square may not always be a rectangle.

Does anybody know this?Find the area of the regular polygon
sweet [91]

Answer:

<h2>2,268 square units</h2>

Step-by-step explanation:

Step 1

Find the area of 1 Triangle

To find this, we will use this formula:

A=\frac{1}{2} *B*H

Let's use the formula!

A=\frac{1}{2} *14*27\\=\frac{1}{2}* 378\\=189

<em>The area of 1 triangle is 189 square units</em>

<em></em>

Step 2

Find the area of the whole intire shape by multiplying the area of 1 triangle with the amount of sides.

There are 12 sides, so let's multiply 189 by 12

189x12=2268

<h2>Hence, the area of the regular polygon is 2,268 square units</h2>

X+y+2=-5 -2x-y+2=-1 x-2y-2=0 solve algebraically
Rina8888 [55]

Answer:

x+y+2=-5 -2x-y+2=-1 x-2y-2=0 solve algebraically

x+y+2=-5     equation 1

-2x-y+2=-1    equation 2

x-2y-2=0      equation 3

Add equation 1 + 2+ 3

x+y+2=-5 + -2x-y+2+1 + x-2y-2

x+y+2= -7+2+1-2x+x+y

x+y+2= -4-x+y

x+y+2+4+x-y= 0

2x+6= 0

2x= -6

divide both side by 2

x= -3

from equation 1 insert x

x+y+2=-5

since x=-3

then, -3+2+y= -5

-1+y= -5

y= -5+1

y= -4

Step-by-step explanation:

Solve this equation 2x - 3=2x - 5
Alex
When you calculate 2x-3=2x-5 it’s going to lead as -3=-5, therefore this statement is inaccurate and doesn’t have a value of x, it doesn’t even have a solution.
