The variable Z is directly proportional to X. when X is 15, Z has the value of 45. what is the value of Z when X=23

IrinaVladis [17]

$If\ Z\ is\ directly\ proportional\ to\ X\ then\ \frac{Z}{X}=const.\\------------------------\\X=15\ and\ Z=45\\\\X=23\ and\ Z=?\\\\\frac{Z}{23}=\frac{45}{15}\to\frac{Z}{23}=3\ \ \ \ |multiply\ both\ sides\ by\ 23\\\\\huge\boxed{Z=69}$

How to solve this step by step n get the answer

lana66690 [7]

Answer:

Answer 1 :-

$\implies m_1 = -3$

$\implies y - intercept = 7$

Answer 2 :-

$\implies m_1 = -\dfrac{1}{2}$

$\implies y - intercept = -4$

Step-by-step explanation:

The Slope Intercept Form of the line is given to us . The equations given are ,

$\implies y + 3x = 7$

$\implies y + \dfrac{1}{2}x = -4$

Now we know the standard equation of slope intercept form , is

$\implies y = mx + x$

Where ,

m is slope
c is y intercept .

So , we can write about the equations as ,

$\implies y = -3x + 7$

$\implies y = - \dfrac{1}{2}x -4$

On comparing to the Standard form ,

Answer 1 :-

$\implies m_1 = -3$

$\implies y - intercept = 7$

Answer 2 :-

$\implies m_1 = -\dfrac{1}{2}$

$\implies y - intercept = -4$
