Answer:

  A.  slope = -2; point = (8, -3)

Step-by-step explanation:

Compare to the point-slope form for slope m and point (h, k).

  y -k = m(x -h)

You see that k = -3, m = -2, h = 8, so ...

  • the slope is -2
  • the point is (h, k) = (8, -3)

Following:

3 ( x^2    -    4   )

Factor:

3x^2   -  12

Factor Out Common Term 3:

3 ( x^2    -  4  )  =  3 (x^2  -  4 )

Factor:

x^2  -  4

( x  +   2 )  ( x   -  2 )

Answer:

3 ( x  +  2) ( x  -  2)

: Ruben put an empty cup underneath a leaking faucet. After 1 1 2 112 hours, Ruben had collected 1 4 14 cup of water. What is th
slamgirl [31]

Answer:

The rate is \frac{1}{6} cups per hour

Step-by-step explanation:

It took the faucet 1 1/2 hours equivalent 3/2 hours to fill 1/4 cup by leaking

We need to find the rate in terms of cups that can be filled by water in 1 hour.

Using unitary method:

it takes \frac{3}{2} h for \frac{1}{4} cup

it will take 1 h for how many cups?

= \frac{1 \times \frac{1}{4} }{\frac{3}{2} }= \frac{2}{4 \times 3}= \frac{2}{12}= \frac{1}{6} cups

Hence, the rate is \frac{1}{6} cups per hour

Solve for x: 4 over x equals 5 over 10
julsineya [31]

Answer:

x = 8,

Step-by-step explanation:

\displaystyle \frac{4}{x} = \frac{5}{10}.

x \ne 0 for it is a denominator. Multiply both sides with the product of the two denominators: 10\;x:

\displaystyle \frac{4}{x}\cdot (10\; x) = \frac{5}{10}\cdot (10\;x).

40 = 5\; x.

Multiply both sides by one over the coefficient of x:

\displaystyle \frac{1}{5} \times 40 = \frac{1}{5}\times 5\; x.

x = 8.
