General Formulas and Concepts:
<u>Algebra I</u>
Coordinate Planes
- Coordinates (x, y)
- Intersections b/t 2 lines
- Graphing
Step-by-step explanation:
<em>Note:</em>
Where the 2 lines intersect is the solution to the systems of equations.
simple first we find the miles per gallon
so 300/15=20 therefor he would only need a extra 3 gallons to go 360 miles so your answer is
B.18
Answer:
5. 1/9? 6. -22? 7. -2? 8. -15? 9. -5? 10. 5?
Hi I don’t understand what you mean by the 10-5 and those others but if u mean order the numbers 8.1,6.5,5.2 from least to greatest then I can do that it’s 5.2, 6.5, 8.1 hope that helped
Answer: I’ll give you an example of how to do it by solving number 9 - h^2 + 8h + 16
Step-by-step explanation:
Step 1: Find two numbers that when you multiply them it gives you the first term’s coefficient multiplied by the last term’s coefficient (1x16 = 16) and when you add them it gives you the second term’s coefficient (8). The numbers in this case are positive 4 and positive 4.
Step 2: Create two parenthesis with the letter accompanied by the numbers. (h + 4)•(h+4). And that’s how you factor.
In case the first term is elevated to the third you will have to take out GCF (greatest common factor) first. If the numbers are too high like in the exercise number 15 you can also take out GCF and it will make it a lot easier to solve. Sometimes what you write on the parenthesis in the step 2 can be simplified, if that’s so then you would have to do it in order to get the correct answer.
Hope this helps you.
