I'll help with a few because no-one wants to just do your homework
there is the formula way or the intuitive way
(-19, -2) (-17, -10)
now slope is (difference in y)/ (difference in x)
or
(y2 - y1)/(x2 - x1) the formula. where x2 just means the second x
<u>formula way:</u>
(-19, -2) (-17, -10)
(-10 - (-2))/ (-17 - (-19)) ReM: Negative on number and in the formula
(-10 + 2)/ (-17 +19) = -8/2 slope is - 8/2
<u>intuitive way</u>
(-19, -2) (-17, -10)
(difference in y)/ (difference in x)
lets looks at the ys
-2 and -10; how many steps from -2 to -10? -8 the diff in y
lets looks at the xs
-19 to -17; how many steps from -19 to -17? + 2 the diff in x
so its -8/2
Solutions
<span>A circle is divided into 9 equals parts. A circle is a round, therefore it has 360°. To solve the problem we have to use division.
360</span>° ÷ 9 = 40
40° is the <span>angle measure of two of those parts. </span>
There are 8 black chips and 6 white chips, 14 chips in total. In this situation the probability to pick a black chip is 8/14=4/7.
When one white chip was removed, then only 5 white chips left and the total number of chips became 13. In this situation the probability to pick a black chip is 8/14=4/7.
When second white chip was removed, then ther left 4 white chips and the total number of chips became 12. Now the probability to pick a black chip is 8/12=2/3 as needed.
Answer: Must be removed 2 white chips. Correct choice is B.
The symmetric property of equality.
This property states that: if a = b, b = a.
