- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 2x - 4
y = -x + 5
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 2x - 4 = -x + 5
- Add <em>x</em> to both sides: 3x - 4 = 5
- Add 4 to both sides: 3x = 9
- Isolate <em>x</em>: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = -x + 5
- Substitute in <em>x</em>: y = -3 + 5
- Add: y = 2
If you meant to write ax^n, then yes this is a polynomial as long as n is a positive whole number.
Something like 2x^3 is a polynomial but other things like 7x^(1.5) or 3x^(-5) are not polynomials.
The value of 'a' does not determine if ax^n is a polynomial or not.
Answer:
Associative
Step-by-step explanation:
The associative property of addition states that you can add numbers however they are grouped inside parentheses.
It doesn't matter where you put the parentheses. You will always get the same answer.
For example,
![\begin{array}{rcl}(5 + 3) + 7 & = & 5 + (3 + 7)\\8 + 7& = & 5 + 10\\15 & = & 15\\\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Brcl%7D%285%20%2B%203%29%20%2B%207%20%26%20%3D%20%26%205%20%2B%20%283%20%2B%207%29%5C%5C8%20%2B%207%26%20%3D%20%26%205%20%2B%2010%5C%5C15%20%26%20%3D%20%26%2015%5C%5C%5Cend%7Barray%7D)
Answer:
$0.75
Step-by-step explanation:
convert 5000 milligrams to grams which is 5.
Then multiply 5 by 0.15 to get the price which is 0.75
The answer is B. 17 days
First you subtract 3,233.54 from 269(3.92)
Then you’ll get 2,179.06
Then you simply divide 2,179.06/124.26
Which equals 17.5362....
I really hope this helps :)
