Answer:
3 both ways x = 3
EXPLANATION:
plug in inputs and do a little simplifying we get
x = 6 ± √(36-36) all of that over 2
So we simplify and we get 6±sqrt(0) / 2
Then we get 6/2 = 3
x-0 = x+0
thats why there is only one answer
Answer:
a
POPULATION : The population is the surfers , swimmers, snorkelers and spear-fishermen in America
SAMPLE : The 1000 records of shark attacks selected
VARIABLE FOR STUDY: 580 surfers
Step-by-step explanation:
Generally the population is the surfers , swimmers, snorkelers and spear-fishermen in America
This is because it is the entire pool from which a statistical sample is drawn
Generally the sample is the 1000 records of shark attacks selected
This is because this the number drawn from the population for statistical testing also this contain the characteristics of the population
Generally the variable for study is 58% of 1000 = 580 surfers
This is because the this 580 surfer is the major focus of the Researchers study
Answer:
8, 12 ,5 I was taking a assignment with that question.
Step-by-step explanation:
I think the answer is A) 2b because when you substitue it for a, you get this equation:
2b = 5b - 3
Once you solve it, shown below:
2b - 5b = -3b <span>÷ -3
</span>b = 1
You get the answer b = 1. If you try the rest of the answers, you don't get a full answer.
Hopefully that helped! :)
Collect like terms
so take it in steps :
1) -4x^3 * x^-8 . rules of powers state that when you are multiplying like terms(both have to do with x) you can add the powers. thus = -4x^-5
2) 2y^-2 * 5y^5 . same rule as above. since -2+5=3. the number before your coefficient (x or y) tells you how many lots of it you have . the answer becomes 2*5y^3 = 10y^3 .
3) since you are now left with x and y s which are not the same number, you can multiply out ---> 10*-4 = -40
---> y^3*x^-5 stays the same as you can not combine y and x
In total you have : -40y^3*x^-5
