How do you draw a graph of
- INTERCEPT METHOD,
- set both values to zero
how do you solve:
What kind of problem is it?
First, find the LCD to get rid of the fractions
multiply by the least common denominator then cross divide.
do the same for the second
- multiply for the LCD
- then cross divide, equalling:
then line each equation up and see which variables will cancel each other
the Y will add up, only if they were positive and negative, so multiply by a 2.
solve for X,
- plug it in to the other equation.
- solve for Y
since it has an equal sign,
what should u remember to do?
Do what ever operation to both sides
How many pounds of candy should there be?
set up the equation
3.75+5(35)= ( x+35) (4.25)
multiply by a hunnet
375x + 5(35)(100)=(0+35)(425)
Subtract the sum of 5x+3 & x2-x-8 from 3x-5
- first, line them up and subtract,
- FOLLOW THE FLOW
now the 2nd part, subtract
(3x-5) - (x2
- CHANGE THE SIGNS,
- then proceed to combine/do operations
When you see
(3x-5) - (x2+4x-5)
what should you do?
Use the subtraction to flip the 2nd equation
use the exponent to split it into 2
(x-y)2 - (x-y)2
In order to simplify, you must first split them
- then foil
Plane travels 150MPH with a head wind at 90 miles per hour, with a tail wind, what is the current speed?
Set it up,
- You want to find current speed,
- you don't know it so
- current speed = X
speed of wind= Y
tail wind= x+y
head wind is= x-y
add them together,
First, change it into positive using the formula
- 1 1 -1
- - + -
- 25 13
- Then solve what's inside
move apples with apples,
then apply the exponent
What is the scientific notation of
first move the decimal creating a number from 1-10
- the number of times you move create the number
left is positive
right is negative
Simplify using scientific notion
- make it a number from 1-10
- the number of decimal counts determine the positive or negative
- 2.4x10-1 x 5x10-------------
Take out the x
then do the A C method
What can multiply to 6 and equal to 7? 6+1
find the square of the number
52 - Y2
then split it
- what 2 numbers equal 16
- Now factor
- AC method will work.
- Set them both to 0
- x=2 x=-1
What is the quadratic formula?
- X=-B plus or minus(+ or -) square root B2-4AC
How do you use the Quad formula?
A+B+C, fill it in, solve
