Answer:
1. -√19 2. 4.56 3. √21 4. 23/5
Step-by-step explanation:
Answer:
yes it is a function
Step-by-step explanation:
You have to take the numbers and see if any of them are the same in the X column if their are some of the same numbers you only write the number once. than you connect the numbers to the given output. If any numbers have 2 outputs it is not a function.
Answer: for example (-2,-2), (-3,-6), and (-8,-10)
Step-by-step explanation: every point in the third quadrant is both negative.
For this case we have the following polynomial:
7x2 + 68xy - 20y2
Factoring we have:
(7x-2y) (x + 10y)
We verify the factorization:
7x2 + 70xy - 2xy - 20y2
Rewriting we have:
7x2 + 68xy - 20y2
Therefore, the factorization is correct.
Answer:
A) (7x - 2y) (x + 10y)
In an equation using x is just a place holder because those numbers are variables so it doesn't matter whether it is x or w.
