Does there exist a function that is not a relation

Setler79 [48]

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.

What is the distance between (-2 1/2, -3) and (1, -3)

Igoryamba

Answer:

D

Step-by-step explanation:

(-2 1/2, -3) = (-5/2 , -3) & (1, -3)

$Distance=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\ =\sqrt{(1-[\frac{-5}{2}])^{2}+(-3-[-3])^{2}}\\\\ =\sqrt{(1+\frac{5}{2})^{2}+(-3+3)^{2}}\\\\ =\sqrt{(\frac{7}{2})^{2}} \\\\=\frac{7}{2}\\\\=3\frac{1}{2}$

Which system of inequalities represents region Z?

ANTONII [103]

Answer:

The system of inequalities is

$y\geq 3x-2$

$y$

Step-by-step explanation:

step 1

Find the equation of the solid blue line

Let

$A(0,-2), B(1,1)$

Find the slope of AB

$m=(1+2)/(1-0)=3$

The equation of the line into slope intercept form is equal to

$y=mx+b$

we have

$m=3$

$b=-2$ ----> the point A is the y-intercept

substitute

$y=3x-2$ -----> equation of the solid blue line

The solution of the inequality is the shaded area above the solid line

therefore

The first inequality is

$y\geq 3x-2$

step 2

Find the equation of the dashed red line

Let

$C(0,2), D(5,1)$

Find the slope of CD

$m=(1-2)/(5-0)=-1/5$

The equation of the line into slope intercept form is equal to

$y=mx+b$

we have

$m=-1/5$

$b=2$ ----> the point C is the y-intercept

substitute

$y=-(1/5)x+2$ -----> equation of the dashed red line

The solution of the inequality is the shaded area below the dashed line

therefore

The second inequality is

$y$

The system of inequalities is

$y\geq 3x-2$

$y$
