Answer:

2931 9/16in^{3}

Step-by-step explanation:

change them to decimals

19 7/8= 19.875

14 3/4= 14.75

10=10

V= lxwxh

V =19.875*14.75*10

V= 2931.5625

Now convert back to a mixed number

2931 5625/10000

Put answer in lowest terms

2931 5625/10000

Divide both sides by 625

2931 9/16in^{3}

The function f is defined by f(x) = 2x²-1.<br> Find f (2x).
umka21 [38]

Answer: f(2x)=8x^2-1

Step-by-step explanation:

All that is required here is to substitute x = 2x into the right side in the same way that is done for a numeric value.

f(2x) = 2(2x)^2-1\\f(2x) = 2(4)x^2-1\\f(2x) = 8x^2-1\\

Choose the point-stope form of the equation below that represents the line that passes through the point (-1, 6) and has a slope
Keith_Richards [23]

Answer:

y-6 = -3(x+1)

Step-by-step explanation:

The point-slope form of a line is the following:

y-yo = m(x-xo), where 'm' is the slope and (xo, yo) is any point where the line passes through.

In this case, m=-3 and (xo, yo) = (-1, 6).

Therefore: y-yo = m(x-xo) = y-6 = -3(x+1)

In conclusion, the point-slope form of the equation that represents the line that passes through the point (-1, 6) and has a slope of -3 is:

y-6 = -3(x+1)
