Answer:
49 students
Explanation:
Since 70% of the 70 students passed the test, we can multiply 0.70 by 70 to get the number of students who passed the test. The word “of” is a hint that you should multiply.
0.70 * 70 = 49
Answer:
Hello! I am also having trouble in algebra! From what I can see so far this is what the problem should look like...
Step-by-step explanation:
A. Yes, it s a linear function because it matches the equation y=mx+b
B. The domain is 1, 2, 3 , 4, and 5. This is because there are 5 services you can choose from. The domain is discrete because you can't have half a service.
C. Because I'm also doing this book (I'm in Algebra 1 in 8th grade), I'm also just learning this! So sorry, but I don't know how to solve this one either... can someone please help?
Thanks! Also, just a tip, if you're having trouble ever again go to slader.com where they have all the answers to any textbook. They also have really good explanations! However, for this one, I didn't understand it on slader so I came on here! Good luck and if anyone can help with C that would be much appreciated.

Step-by-step explanation:
Answer:
5
Step-by-step explanation:
x^2-7x=30
x^2-7x-30=0
a = 1, b = -7, c = -30
sqrt(b^2-4ac)
sqrt(49+120)
sqrt(169)
13
-b +/- 13
7 + 13 = 20
7 - 13 = -6
2a = 2
20/2 = 10
-6/2 = -3
we know x>0, so it cant be -3. so now its just 10 - 5
