Elina [12.6K]2 years ago

Step-by-step explanation:

Line is passing through the points:

(-2,\:3)=(x_1,\:y_1) \:\&\: (2,\:5)=(x_2 ,\:y_2)

Equation of line in two point form is given as:

\frac{y -y_1 }{y_1 -y_2 } = \frac{x -x_1 }{x_1 -x_2 } \\ \\ \therefore \frac{y -3}{ 3 -5} = \frac{x -(-2) }{-2 -2} \\ \\ \therefore \frac{y -3}{ - 2} = \frac{x -(-2) }{-4} \\ \\ \therefore \frac{y - 3}{1} = \frac{x +2}{2} \\ \\ \therefore \: y-3= \frac{x}{2} + \frac{2}{2} \\ \\\therefore \: y= \frac{x}{2} + 1 +3\\ \\ \huge \red{ \boxed{\therefore \: y= \frac{1}{2} \:x+ 4}}\\ is \: the \: required \: equation \: of \: line.

What is the weight of 320 jars if each jar weighs 3 pounds 2 ounces?
salantis [7]
First, covert 3 pounds to ounces...then add the 2 ounces given. The weight of one jar, in ounces, is 50 ounces. Given that, multiply 320 by 50. The answer to that is 16,000. Therefore, there are 16,000 in 320 jars. To get the answer pack to pounds....divide 16,000 by 16 since there are 16 ounces in a pound. The answer would be 1,000 pounds. Meaning, there are 1,000 pounds OR 16,000 ounces in 320 jars. Hope this helps :)

An electronics manufacturer can produce and sell x MP3 players per week. The total cost C (in dollars) of producing MP3 players
coldgirl [10]

Profit, or the surplus money after your costs are covered, is Revenue - Costs.

so in this case the profit P(x) = R(x) - C(x).


\bf P(x)=(135x)-(93x+35000)\implies P(x)=135x-93x-35000
\\\\\\
P(x)=42x-35000
\\\\[-0.35em]
~\dotfill\\\\
\stackrel{\textit{selling 5000 mp3s}}{P(5000)=42(5000)-35000}\implies P(5000)=210000-35000
\\\\\\
P(5000)=175000

for a science experiment marcia dissolved 1.0 kilograms of salt in 3.0 liters of water for a different experiment Bobby dissolve
Kay [80]
Marcia dissolved 1 kg of salt in 3 litres of water.
Bobby dissolves 2 pounds of salt in 7 pints of water
2.11 pints = 1 litre
7 pints = 7/2.11
           = 3.32 litre
1 pound =0.45 kg
2 pound = o.45*2 kg
               = 0.9 kg
So we find that Bobby is dissolving 0.9kg of salt in 3.32 litre of water
Marcia is dissolving 1 kg of salt in 3 litres of water.
So it can be said that Marcia made a more concentrated salt solution.
