C.) R olling a 6; rolling an odd number

- 'mutually exclusive' means they cannot happen at the same time.

- 'C' is mutually exclusive as with one roll of the die, you cannot get a 6 and an odd number.

How do you simplify this equation

Nat2105 [25]

3 ( x + 1) = 2 ( x + 11) Use the Distributive Property
3x + 3 = 2x + 22 Subtract 2x from both sides
x + 3 = 22 Subtract 3 from both sides
x = 19

What is the distance between the points (-4, 6) and (1, -6)?

Oksanka [162]

Answer:

The distance between these 2 points is 13.

Step-by-step explanation:

Picture the 2 points on a graph as a right triangle, where the hypotenuse of that right triangle is the distance between the points. It is very easy to find the length of the legs of that triangle, and you can use those legs to calculate the length of the hypotenuse.

First, find the vertical distance, or the distance between the y-coordinates. Either just look at a graph and count, or subtract them.

$-6-6=-12$

Distance is an absolute value from 0, so -12 is the same as 12.

Next, find the horizontal distance between the x-coordinates.

$1--4=5$

Now, we have the length of the legs, 5 and 12. Use the pythagorean theorem to find the length of the hypotenuse:

$a^2+b^2=c^2\\5^2+12^2=c^2\\25+144=c^2\\c^2=169\\c=\sqrt{169}\\c=13$

The distance between these 2 points is 13.

Find the length of the line segment shown. Round your answer to the nearest tenth.

Marina86 [1]

Answer:

$d=10$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step 1: Define endpoint coordinates

(2, 5)

(-6, -1)

Step 2: Substitute and Evaluate

$d=\sqrt{(-6-2)^2+(-1-5)^2}$

$d=\sqrt{(-8)^2+(-6)^2}$

$d=\sqrt{64+36}$

$d=\sqrt{100}$

$d=10$

Help any one? Pls you’ve been so helpful pls don’t let it end

Leona [35]

You missed one final step, no worries! When finding the percent off, subtract the value you got after dividing the price after discount by the initial price from 100.
So: 100 - 65 = 35

35% off

Hope this helps!
