\frac{3}{2}k - 7 = \frac{k}{4} - 2

Since our fractions have two different denominators of 2 and 4 in this equation, we can get rid of the fractions by multiplying both sides of the equation by their common denominator, which is 4.

So we have (4)(\frac{3}{2}k - 7) = (\frac{k}{4} - 2)(4).

Make sure you distribute the 4 through both

terms on both sides of the equation.

On the left, (4)(3/2k) is 6k and (4)(-7) is -28.

On the right, (4)(k/4) is k and (4)(-2) is -8.

So we have 6k - 28 = k - 8.

Now subtract k from both sides to get 5k - 28 = -8.

Now add 28 to both sides to get 5k = 20.

Finally, dividing both sides by 5, we find that <em>k = 4</em>.

Verizon [17]

Answer: 50 cases per minute

Step-by-step explanation:

1. Select one of the points on the graph. Let's use (2, 100) in this case.

2. Divide the number of cases (y) by the amount of minutes (x) This means the equation would be 100 ÷ 2.

3. Since 100 cases ÷ 2 minutes = 50 cases per minute, that means that is unit rate, which can be expressed by y = 50x or f(x) = 50x.

Answer:

  (6, 6)

Step-by-step explanation:

Each grid square is 2 units. 10 units up from point P is 5 grid squares up, or 3 grid squares above the x-axis. The x-coordinate remains the same (6), and the y-coordinate is the one labeling the 3rd line above the x-axis: 6.

The coordinates of point S are (6, 6).
