Answer:
odd
Step-by-step explanation:
Just so you know there are shortcuts for determining if a polynomial function is even or odd. You just to make sure you use that x=x^1 and if you have a constant, write it as constant*x^0 (since x^0=1)
THEN!
If all of your exponents are odd then the function is odd
If all of your exponents are even then the function is even
Now you have -4x^3+4x^1
3 and 1 are odd it is an odd function
This a short cut not the legit algebra way
let me show you that now:
For it to be even you have f(-x)=f(x)
For it be odd you have f(-x)=-f(x)
If you don't have either of those cases you say it is neither
So let's check
plug in -x -4(-x)^3+4(-x)=-4*-x^3+-4x=-4x^3+-4x
that's not the same so not even
with if we factor out -1 .... well if we do that we get -(4x^3+4x)=-f(x)
so it is odd.
Answer:
For question 1 you can try dividing each of the value
For instance, you can divide 9 by 25 and see if you get a nice number
e.g. 1/8=0.125, numbers like these
For the second question, you can find the fraction by dividing 1000 starting with the decimal points
e.g 0.650, you would be plotting 650/1000 and you would simplify the fraction to the lowest value any value above the decimal point you can multiply by the denominator and add the nominator value to get your final answer.
Step-by-step explanation:
a) Rainbow phone: c=100+6x
Cellular phone: c=80+10x
b) make the equations equal to each other:
100+6x=80+10x
20=4x
5=x
5 GB over
c)if x=6
Rainbow: 100+(6 x 6)= $136
Cellular: 80+(10 x 6)=$140
Therefore rainbow will save them the most money
The number or letter to eliminate are 2 and 5
<h3>How to determine the number or letter to eliminate?</h3>
The equation in the question is given as:
y = 2x + 5
Subtract 5 from both sides of the equation
So, we have:
y - 5 = 2x + 5 - 5
Evaluate the like terms
So, we have:
y - 5 = 2x
Notice that the number 5 has been eliminated from the side of x
Next, we divide both sides of the equation by 2.
So, we have:
(y - 5)/2 = 2x/2
Evaluate the quotients
So, we have:
(y - 5)/2 = x
Notice that the number 2 has been eliminated from the side of x
Hence, the number or letter to eliminate are 2 and 5
