Answer: -2.85
Step-by-step explanation:
To convert 22/20 into a decimal, we must multiply it by 5 to get a denominator of 100.
5(22/20)= 110/100= 1.10
So now lets solve the equation.
-1.75-1.10 = -2.85
Problem # 1
Not Factored: (5x^2 - 13x - 6)
Factored: (5x + 2 )(x - 3)
There is no real "work" to be shown for this, you can see that
1) Seperating 5x^2 into 5x and x will get you the equation in the form:
(5x ) (x ) = 5x^2 +
2) To complete this factor you need to guess which two numbers will add together to give you - 13x and multiply to form -6 (from the original unfactored equation). The numbers that will do this are 2 and 3
3) You can plug in negative or positives of those numbers to make sure they give you the exact results you need.
For example testing -2 and 3 you will get: (5x - 2) (x + 3 ) = 5(x^2) - 2x + 15x - 6 = 5x^2 +13x - 6. This is NOT the same as the unfactored equation. So you know -2 and 3 is the wrong choice. Choosing 2 and -3 will give you the answer instead.
As i said, there's no actual "work" to show this, you have to make guesses and try to factor it.

Problem # 2
Not Factored: 4x^4 - 28x^3 + 48x^2
Factored: 4x^2 (x^2 - 7x + 12) =
4x^2 (x - 3) (x - 4)
To solve this, you factor out the 4x^2 from the entire equation. Then you can further factor the quadratic equation by seperating x^2 into (x )(x ) and guessing for which numbers will add to -7x and multiply to 12
Answer:
Metaphor
Step-by-step explanation:
This is a comparison between the ocean and a magnet, but it did not use like or as, so it is a metaphor.
Answer:
A
Step-by-step explanation:
Domain is all the x values
Range is all the y values
Answer:
1 7/30
Step-by-step explanation:
3 - (1 1/6 + 3/5) =
3 - (1 5/30 + 18/30) =
3 - 1 23/30 =
1 7/30
