What is the distance between the two points (5,-2) and (-3,8)
bearhunter [10]
You need to use the distance formula
d =  \sqrt{ {(x - x)}^{2}  +  {(y - y)}^{2} }

\sqrt{ {(5 + 3)}^{2}  +  {( - 2 - 8)}^{2} }
so the distance between points (5,-2) and (-3,8) is
2 \sqrt{41}
which won't simplify so it stays as is

There are 6 pennies, 9 nickels, and 3 dimes in a box. Find the probability of P(1 nickel and then 1 dime)—with replacement. what
densk [106]

<u>The probability is </u><u>1/12</u>

The probability of choosing a nickel is 9/18 = 1/2. The probability of choosing a dime is 3/18 (because there are 3 dimes and since there is replacement, we still have 18 total coins to choose). With these, we get: (1/2) * (3/18) = 3/36 = 1/12

What is 5( x - 3 ) = 5x - 15?
Volgvan

\tt5( x - 3 ) = 5x - 15 \\  \tt5x - 15 = 5x - 15 \\ \tt5x - 5x =  - 15 + 15 \\ \tt\bcancel{5x} - \bcancel{5x} =  \bcancel{- 15} + \bcancel{15} \\ \boxed{\tt0 = 0}

  • The answer is <u>0</u><u>.</u>
  • LHS = RHS, hence verified.

<u>Value of x (substitute 0 in the place of x).</u>

\tt5( (0) - 3 ) = 5(0) - 15 \\  \tt0 - 15 = 0 - 15 \\  \tt \boxed{\tt -15 = -15}

  • So, value of x is <u>0</u><u>.</u>
