we know that
Two angles are supplementary if their sum is equal to 
degrees
in this problem we have
so
therefore
<u>the answer is</u>
The two angles are supplementary
Answer:
-4y^3 + 4y^2 - 6y + 25
Step-by-step explanation:
<u>Step 1: Distribute the plus</u>
(-4y^3 – 5y +16) + (4y^2 – y + 9)
-4y^3 - 5y + 16 + 4y^2 - y + 9
<u>Step 2: Combine like terms</u>
-4y^3 - 5y + 16 + 4y^2 - y + 9
-4y^3 + 4y^2 - 6y + 25
D. (-8,-7) Simplifying<span>y + -8 = 4(x + 7)
Reorder the terms:
-8 + y = 4(x + 7)
Reorder the terms:
-8 + y = 4(7 + x)
-8 + y = (7 * 4 + x * 4)
-8 + y = (28 + 4x)
Solving
-8 + y = 28 + 4x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '8' to each side of the equation.
-8 + 8 + y = 28 + 8 + 4x</span>
The probability of randomly getting first a red marble and then a blue marble is:
P = 0.083
<h3>
How to find the probability?</h3>
There are:
- 3 blue marbles
- 2 red marbles
- 4 yellow marbles.
For a total of 9 marbles.
The probability of getting a red marble is equal to the quotient between the number of red marbles and the total, so:
P(red) = 2/9
Then the probability of getting a blue marble is equal to the quotient between the number of blue marbles and the total, but because we already took one marble, now the total is 8.
P(blue) = 3/8
The joint probability is given by the product:
P = (2/9)*(3/8) = 0.083
