Solve a / a-1 - a+5/a =0. Enter your solution as an improper fraction or as a decimal rounded to the nearest hundredth
Flauer [41]

Answer: 1\dfrac{1}{4}

Step-by-step explanation:

Given

The equation in terms of a is

\Rightarrow \dfrac{a}{a-1}-\dfrac{a+5}{a}=0\\\\\Rightarrow \dfrac{a}{a-1}=\dfrac{a+5}{a}\\\\\Rightarrow a^2=(a-1)(a+5)\\\\\Rightarrow a^2=a^2+4a-5\\\\ \Rightarrow 4a=5\\\\\Rightarrow a=\dfrac{5}{4}\ \text{or}\ 1\dfrac{1}{4}

Point Z is located at (3,4). The point will be translated 2 units left and 4 units up. What will be the coordinates of the image
Firlakuza [10]

Z (3, 4 ) → Z' (3 - 2, 4 + 4 ) → Z' (1, 8 )

The table shows the toothbrush production rate of One machine. Toothbrush Production Minutes 2 4 6 8 10 Toothbrushes 140 280 | 4
Klio2033 [76]

9514 1404 393

Answer:

  c)  70 toothbrushes per minute

Step-by-step explanation:

The table tells you that production is 140 toothbrushes in 2 minutes. Dividing toothbrushes by minutes gives you the "per minute" value:

  (140 toothbrushes)/(2 minutes) = (140/2) toothbrushes/minute

  = 70 toothbrushes/minute
