General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
- Combining Like Terms
- Standard Form: ax² + bx + c = 0
Step-by-step explanation:
<u>Step 1: Define expression</u>
5x² - 36x - 81
<u>Step 2: Simplify</u>
<em>We cannot simplify the expression down further.</em>
3+2•6/3
first you multiply the 2 and 6 on the top to get 12
so now it’s
3+12/3
now add the 12 and 3
15/3
now divide
so your answer is 5
It crosses the x axis when y = 0.
so we need to solve x^2 - x - 2 = 0.
This is done as follows:
x^2-x-2=0
(x-2)(x+1) = 0
Therefore x = 2 or x = -1.
So the two coordinates are (2,0) and (-1,0) the answer is A
Y = 1.5x + 6.5
hope this is helpful!
