What is 3.875 rounded to the nearest cent?

1 answer:

Ronch [10]3 years ago

The answer should be 3.88 because when people talk about ''cent'' that usually refers to nearest hundredth so round it and that would be 2 decimal spaces so go from left to right and count twice after 3, and round <u>7</u> up by 1 and that would be 8, so 3.88 should be it.

Answer:

$y=\frac{-1}{6}x-\frac{10}{3}$

Step-by-step explanation:

Slope intercept form of the equation of a line is $y=mx+b$ where m denotes the slope of line and $b$ denotes the y-intercept.

Equation of a line u is $y=6x+6$

Here, slope of line u = m = 6

As the line v is perpendicular to line u, product of slopes of both the lines is equal to $-1$ .

Slope of line v $=\frac{-1}{6}$

So, slope intercept form of the line v is $y=\frac{-1}{6}x+b$

As point $(10,-5)$ lies on the line v, put $(x,y)=(10,-5)$ in equation $y=\frac{-1}{6}x+b$

$-5=\frac{-1}{6}(10)+b\\-5=\frac{-5}{3}+b\\ -5+\frac{5}{3}=b\\\frac{-15+5}{3}=b\\\\\frac{-10}{3}=b$

Equation of line v is $y=\frac{-1}{6}x-\frac{10}{3}$
