Step-by-step explanation:
Answer: Interval = [103,∞)
Explanation :
A medicine become ineffective if its temperature ever reaches 103 degrees Fahrenheit or more .
So, Interval becomes [103,∞)
i.e. semi-open or semi-closed interval as it includes 
So, we used closed brackets i.e. square brackets and
For '∞' we always use open brackets only.
Answer:
1) 2<x<10 (the first choice)
2) 17<u><</u>x<40 (the first choice)
3) x<u><</u>-1 or x<u>></u>2 (the second choice)
Step-by-step explanation:
1) 2<x<10...this is another way of representing x<10 and x>2 in an "and" inequality. If you look at 2<x<10 from left to right, it says 2 is less than x and x is less than 10.
2) 17<u><</u>x<40...this represents x<u>></u>17 and x<40 in an "and" inequality as well. If you look at 17<u><</u>x<40, it reads 17 is less than or equal to x and x is less than 40.
3) x<u><</u>-1 or x<u>></u>2...the signs are greater than or equal to because the dots are closed on the number line. Also, this is not an "and" inequality. This is actually an "or" inequality. You can mainly tell because the lines are shaded opposite ways and do not intersect.
I hope this helped!! Good luck on your assignment and have a wonderful day :3
Answer:
Step-by-step explanation:
Let 
represent a small box of pencil and 
represent a large box of pencil.
We were told that "A large box has ten times as many pencils as a small box". This statement gave the equation;
If Mr. Adachi buys 5 small boxes and 2 large boxes, for a total of 250 pencils, then the equation Mr. Adachi set up was;
where 
and 
has no common factor other than 1.
We are given the expression
5⁹ x 5³
We can solve this using the rule of exponents which is
a^n x a^m = a^(a + m)
Therefore, the answer is
to keep the base and add the exponents
5⁵⁺³ = 5⁸<span />
