Triangles
What is the formula for a right triangle?
In the formula y = 4x + 5 what does 5 represent?
5 is the y intercept (where you start)
How would I put 100 in scientific notation
1.0 x 10 to the power of 2
In the following problems, what terms can I combine? What do I get when I combine them? Why can I combine them?
3x + 5 - 8x + 2 = 27
3x and -8x get -5x. 5 and 2 get 7. You will get
-5x + 7= 27
You can combine them because they are similar. 3x and -8x both have x and 5 and 2 are just numbers.
If I have the following...
510 divided by 54
What do I do with the exponents to find the solution?
Subtract the exponents.
How many degrees in a triangle?
180 degrees
In the formula y = 8x + 2 what number goes under 8?
1
5.0 x 10 to the power of -4
In the equation below, what do I move first? Why?
5x + 2 = 12
2 because you want to move the number not touching the letter first.
If I have the following..
319 x 34
What do I do with the exponents to find the solutions?
Add the exponents. 19 + 4 = 23
Solution = 323
If two angles are opposite of each other (Mr. Kain will draw an example) what is their relationship?
They are equal.
If a slope is -3x I go 3 spots _____ and 1 spot _______. If a slope is 3x I go 3 spots _______ and 1 spot ________.
Down
Right
Up
Right
How would I put 35,000 in scientific notation?
3.5 x 10 to the power of 4
How do I split a number and a letter when they are touching? How do I move a number when it is not touching a letter? Which do I move first if I have both?
EX: 9 + 3x = 90
You move a number touching the letter by dividing. You move a number not touching a letter by doing the opposite (If positive, you subtract, if negative, you add)
If an exponent is negative like so 5-8 how do I simplify?
It needs to be put at the bottom of a fraction. Like 1/58
How would I set up a triangle problem where the interior angles are 35 degrees, 50 degrees and 19x degrees?
35 + 50 + 19x = 180
In the formula y= -x - 2 where do I start on the y axis and how do I continue?
I start and -2 and continue by going down 1, right 1.
What button do I press in my calculator to help me put something in scientific notation?
EE
In the equation below, how do I get the 2 to the other side? How do I get the eight to the other side?
2 + 8x = 50
You move the 2 by subtracting. You move the 8 by dividing.
If I have a power to a power, what do I do with the exponents?
Multiply
How do I know if 3 lines make a triangle? How do I know if they make a right triangle?
For a triangle the two smaller lines have to be bigger than the biggest line when added together. For a right triangle, the two smaller lines squared have to be EQUAL to the biggest line squared.
Which of these equations makes a proportional relationship?
y = x
y=5x + 2
y = x + 3
y= 4x
y = x
y = 4x
Put 534.5 x 1012 in scientific notation.
5.345 x 1014
If I have x2 = 9 how do I find what x is. If I have 2x = 8 how do I find out what x is?
What is 53 x 42 x 59 simplified
511 x 42
