The vertical line test is when you put vertical lines down the graph and if the point does not touch the line more than once, it passes and represents a function.
Answer: option B is the correct answer
Step-by-step explanation:
On her math test, Heidi correctly
answered 35 of the 40 questions. This means the total number of questions in the math test is 40. If she was able to answer 35 correctly, that means the number of questions that she failed is total number of questions - the number of questions that she answered correctly. This becomes 40-35 = 5
This means that she failed 5 questions.
To find the percentage of questions that Heidi answered correctly, we will divide the number of questions that Heidi answered correctly by the total number of questions and multiply by 100%. It becomes
35/40 × 100 = 0.875 × 100
= 87.5%
Heidi answered 87.5% of the total questions correctly

well, if he gave his dog 1/5 of the money, what's left is just 4/5, recall 5/5 is a whole, so
now, let's divide that 4/5 in 3 even pieces
now, his donation to each charity was 60 bucks, so 4/5, of say "x", "x" being to total amount, is 60, thus (4/5)x = 60
and surely you know how much that is.
Answer:

Step-by-step explanation:
3:1:4 original ratio
60:?:? question
60/3=20=1 part
60:20:? last solving
4 X 20= 80
60:20:80
X^2 + 2x - 3 = (x-1)(x+3)
