Answer:

The correct answer is A.) Always

Step-by-step explanation:

A function is defined as a relation in which each element of the domain is mapped to one element of the range. In the definition itself, it is defined as a relation

The measure of arc BCD is

makkiz [27]

Answer:

m∠BCD = 140°

Step-by-step explanation:

ABCD is cyclic quadrilateral. A property of cyclic quadrilateral states that the opposite angles of it sum up to 180°. Here:

m∠A + m∠C =180° and m∠B + m∠D = 180°

So, m∠A + m∠C =180°

m∠A = 40° (given in the question)

40° + m∠C = 180°

m∠C = 180° - 40° = 140°

∴m∠C = m∠BCD = 140°

What is the distance between the points (-3,5) and (3,-8) in the standard (x,y) coordinate plane?

zlopas [31]

The vertical distance is 5 + 8 = 13
the horizantal distance is 3 +3 = 6
then just do pythag therom
6^2 + 13^2 = c^2
205 = c^2
<span>√205 = c

Dominique needs to solve the system of equations by graphing. Which statement is true about the system? 2 x minus 3 y = 12. Y =

Nutka1998 [239]

Answer:

Option C) The first equation is y= 2/3x-4 when written in slope-intercept form .

Step-by-step explanation:

We have

$2x - 3y = 12 \: > \: first \: equation$

The first equation is in Standard form .

Convert to slope Intercept form .

Isolate the Variable y .

$3y = 2x - 12$

Divide by 3 both sides .

$y = \frac{2}{3} x - 4$

$y = - \frac{3}{5} x + 2 > second \: equation$

The second equation is in slope Intercept form .

Convert to standard form

Multiply by 5 both sides to remove the fraction .

$5y = - 3x + 10$

$3x + 5y = 10$

<h3><u>Verify each statement :- </u></h3>

<h3>• case A) Both equations are in slope-intercept form.</h3>

False

Because only the second equation is in slope -intercept form

<h3>• case B) Neither equation is in slope-intercept form .</h3>

False

Because, the second equation is in slope -intercept form

<h3>• case C) The first equation is y= 2/3x-4 when written in slope-intercept form</h3>

True (see the procedure)

<h3>• case D)The second equation is 3x+5y=10 when written in slope-intercept form.</h3>

False

Because, the second equation is 3x+5y=10 when written in standard form .
