Answer:
x = - 4, x = - 
Step-by-step explanation:
To find the zeros let g(x) = 0, that is
(- 5x - 1)(2x + 8) = 0 ← in standard form
Equate each factor to zero and solve for x
- 5x - 1 = 0 ( add 1 to both sides )
- 5x = 1 ( divide both sides by - 5 )
x = 
= -
2x + 8 = 0 ( subtract 8 from both sides )
2x = - 8 ( divide both sides by 2 )
x = - 4
Thus
smaller x = - 4
larger x = -
An irrational number is one that cannot be shown as ratio of two integers, an 3.14=314/100 so that means pi is irrational. Another thing to note is that pi is transcendental which means it is not the root of any algebraic equation.
Answer:
16:40, 0.4
Step-by-step explanation:
experimental probability would be a ratio consisting of the number of times the coin lands on heads to the total number of times the coin is flipped so it would be 16 to 40 or simply 16:40
theoretical probability would be a way to show the likeliness of the coin landing on heads and can be found by dividing the number of flips that is expected to land heads up by the total number of flips so you divide 16 by 40 which equals 0.4
Unfortunately your teacher is using x as both a variable and a multiplication sign. This is something that can be avoided by using something like the asterisk symbol to indicate multiplication.
Anyways, notice how the expression 
shows up twice. Once in the numerator (the entire numerator) and once again in the denominator (nearly the whole thing)
Let's replace that messy expression with the variable y. So we're letting 
This means,
At this point you can probably see how to get 
from here. The y terms cancel out when we divide leaving 1 up top and 3^x down below.
There is not enough information in order to solve
