g(-n) = -(n²+5) = -n²-5
f(g(-n)) = 2n+1 (-n²-5 )
2n(-n²-5)+1(-n²-5 )

so we notice that if we solve the second equation (3+y=6), we get a value for y and no value for x so just draw a horizonal line at the point 3 on the y axis
then make the second equation into slope inercept form y=mx+b
x-2y=2
2y-x=-2
2y=x+2
y=1/2x+1
just put in values for x and get y values, then plot points and get line
find where the line inercepts/crosses the first line (3+y=6) and that is the solution
OR
so a the solution is when both equations are true so just assume both are true and solve for x and y
x-2y=2
3+y=6
first of all the second equation is easy
3+y=6
subtract 3 from both sides
y=3
so we subsitute 3 for y in first equation
x-2(3)=2
x-6=2
add 6 to both sides
x=8
y=3
the solution is the point (8,3)

rembmer that percent means parts out of 100 so
x%=x/100
find disctount first
200 minus disctount=130
add discount to both sides
200=130+discount
subtract 130 from both sides
70=discount
original parice=200
dscount=70
percent discount=70/200
convert bottom number to 100 by dividind top and bottom by 2
70/2=35
200/2=100
35/100=35%
answer is 35% discount

The product of (sum of 2 things) (difference of 2 things) = (difference in their squares).
For example: (x + y) (x - y) = (x² - y²)
When you're trying to factor algebra expressions, it's always good to keep your
eyes open for the difference of two squares, and remember that it's going to be
(sum) x (difference) of the things that they're squares of.
Here you have (a sum) x (a difference) of the same 2 things:
(5a + 2bc) (5a - 2bc)
You can multiply them out, or just use the little tool above:
(5a)² = 25a²
(2bc)² = 4b²c²
So (their sum) x (their difference) is (25a² - 4b²c²) .

Answer:
Step-by-step explanation:
Let d be the number of days.
We have been that each day Katie finds 12 more seashells on beach, so after collecting shells for d days Katie will have 12d shells.
We are also told that Katie already has 34 seashells in her collection, so total number of shells in Katie collection after d days will be:
As Katie wants to collect over 100 seashells, so the total number of shells collected in d days will be greater than 100. We can represent this information in an inequality as:
Therefore, the inequality can be used to find the number of days, d, it will take Katie to collect over 100 seashells.
Final answer:
In order to find out when Katie will have over 100 seashells, we use the equation 34 + 12d > 100. After simplifying, the inequality is d > 5.5. So, it will take Katie over 5.5 days to collect over 100 shells.
Explanation:
The question states that Katie already has 34 seashells and finds 12 more each day. This can be represented by the equation 34 + 12d, where d represents the number of days. In order to find out when Katie will have more than 100 seashells, we need to set this equation greater than 100 and solve for d.
So, 34 + 12d > 100. If we subtract 34 from both sides, we get 12d > 66. Then, divide both sides by 12 to solve for d. d > 66/12. The value of d in this case turns out to be approximately 5.5.
This means it will take Katie slightly over 5.5 days to collect over 100 seashells, given that she can use fractions of days to find seashells.
