3.        2x - y = 10
    2x - 2x - y = -2x + 10
                 -y = -2x + 10
                 -1         -1
                   y = 2x - 10
   Slope: 2

4.        5x - 2y = 10
    5x - 5x - 2y = -5x + 10
                 -2y = -5x + 10
                  -2          -2
                    y = 2.5x - 5

5.    y - y₁ = m(x - x₁)
    y - (-2) = -3(x - (-1))
       y + 2 = 3(x + 1)
       y + 2 = 3(x) + 3(1)
       y + 2 = 3x + 3
           - 2         - 2
             y = 3x + 1

Omar is born weighing 8 pounds, and 3 ounces. The doctor says he should gain 5 ounces each week for 4 weeks. How much should omo
Monica [59]

Let's convert 8 pounds and 3 ounces, into all ounces.

So we know one pound = 16 ounces.

1 lb = 16 oz.

Now since Omar is 8 pounds + 3 ounces, we multiply 16 by 8, and add on the 3:

16 * 8 = 128

128 + 3 = 131

So Omar weights 131 ounces when he was born.

Now Omar has to gain 5 ounces each week, for 4 weeks. This means in total, he'll have to gain 5*4=20 ounces in 4 weeks.

Add them together:

131 + 20 = 151 oz OR 9 7/16 lb.

Steven measures how much milk his kitten consumes in cups every day for a week. The line plot displays the results. List the dat
Furkat [3]

Answer:

3 3/5

Step-by-step explanation:

You can see that Steven's cat drank 2/5, Then it drank 3/5. If you add those together, then you get 1. Then it drank 1/2 a cup of milk 4 times, that would equal 2. Then, she drank one more 3/5 cup of milk. Then you add all the whole numbers, which equals 3 then you have that 3/5 left over so its 3 3/5

What is the x And y intercept of (10,0) and (0,-10)
Radda [10]

The y-intercept is found by letting x = 0 and finding / calculating y.  That would be (0, -10).  

The x-int. is found by letting y = 0 and finding x.  That would be (10,0).
