M = 3
passing thru <span>(2,3)
y = mx + b
3 = 3(2) + b
3 = 6 + b
so b = -3

equation : y = 3x - 3</span>

2a - b = ac + 3b for a

DaniilM [7]

Answer:

If your trying to solve for a, I believe this is the answer: a = 4b / (2 - c)

Step-by-step explanation:

2a - b = ac + 3b

First you want to group by like terms, so for "b" you are going to add "b" to both sides so that it cancels out on the left side and you now have all of your "b's" on the right.

2a = ac + 4b

next, you want to get the a's on the left side so you are going to subtract "ac"

2a - ac = 4b

Now, you need to factor the "a" out, and since its the greatest common factor among the "2a - ac" you are left with "a(2 - c)"

a(2 - c) = 4b

Finally divide both sides by "(2 - c)"

a = 4b / (2 - c)

and that's your answer

Walkway Over the Hudson, a bridge that crosses the Hudson River in Poughkeepsie, is 2.063 kilometers long. Anping Bridge, which

Pavlova-9 [17]

a. The total span of both bridges is 4.133 km.

When calculating the total of two different numbers, addition is the correct math operation to be used. We know that we need to add the length of the bridges together because the word <em>span</em> is the same as length. Also, the question asks about both bridges and uses the word <em>total. </em>2.063 + 2.07 = 4.133 km.

b. Leah and her dog will walk 4.126 km.

The question says that Leah walks across and back. This means she goes over the bridge two times. Times indicates that we should use multiplication for our math operation. Since she does the length two times, we need to multiply the length of the Walkway Over the Hudson bridge times 2. The math equation is 2.063 x 2 = 4.126 km.

<h3>Further Explanation</h3>

The profit a company earns every month depends of the amount of the product sold, p, for $855 each and the amount spent in rent,

bearhunter [10]

Answer:

$31,045.50

Step-by-step explanation:

Revenue from sales = ($855/item)p

Expenses: $6,780

Revenue if p = 250 is R(250) = ($855/item)(250 items) = $213,750

Subtracting expenses, we get a profit of $206,970.

The CEO of the company earns 15% of this profit, or:

0.15($206,970) = $31,045.50
