What is an equation of the line that passes through the point (-6,-3) and is parallel to the line 5x-3y=9?
irina [24]

Answer:y=5x/3 +7

Step-by-step explanation:

First, we find the slope of the line parallel. That is clearly, by rearranging, -3y= -5x + 9, and then dividing by -3, the slope is 5/3 .

Now, we know our equation is in the form of y = 5x/3 + b. Plugging in (-6,-3), we have -3 = -10 + b, so b = 7. Therefore, our equation is y= 5x/3 +7.

Given that y varies inversely with x, if x =7 and y = 4, what is y when x = 2?
AysviL [449]

Answer:

y = 14

Step-by-step explanation:

y ∝ \frac{1}{x}

=> y = \frac{k}{x}     -------------(1)

<em><u>Where k is the constant of proportionality</u></em>

Now,

x = 7, y = 4

<em>Putting in (1)</em>

4 = \frac{k}{7}

So,

=> k = 28

Now y = ? when x = 2

<em>Putting x and k in (i)</em>

y = \frac{28}{2}

y = 14
