Step-by-step explanation:

a) \:  \frac{10}{4}  =  \frac{5}{2}  = 2.5

b) \frac{10}{4}  =  \frac{25}{x}   \\  \\ 10x = 25 \times 4 \\ 10x = 100 \\  \\ x =  \frac{100}{10}  = 10 \\  \\ x = 10

Find an equation for the line with the given properties. Perpendicular to the line 7x - 3y = 68; containing the point (8, -8)
Sever21 [200]

Answer:

y=\dfrac{-3}{7}x-\dfrac{32}{7}

Step-by-step explanation:

Given that,

A line 7x - 3y = 68 and containing the point (8, -8).

The equation can be written as :

-3y=68-7x\\\\y=\dfrac{68}{-3}+\dfrac{7x}{3}\\\\y=\dfrac{7x}{3}+(\dfrac{-68}{3})

The slope is :7/3

Line is perpendicular so use m = –3/7

-8=(-\dfrac{3}{7})\times 8+b\\\\-8+\dfrac{3}{7}\times 8=b\\\\b=\dfrac{-32}{7}

So, required equation is :

y=\dfrac{-3}{7}x-\dfrac{32}{7}
