Error Analysis! Answer both parts of the question.
Kaitlyn solved the equation 5y = 15 and found the answer to be y = 75.
(Problem down below in file)
Part A: In a complete sentence or two, explain what Kaitlyn's error was. What did she do wrong?
Part B: What is the correct answer? Show your work and/or explain your reasoning.
Answer:
Kaitlin's answer is wrong because she is supposed to by dividing. When trying to get rid of a number from a variable you have to divide the number by itself and whatever you do to one side you have to do to the other side
so you would do 5/5 - cancels out
15/5=3
y=3
Step-by-step explanation:
have a great day :D
Answer:
y = 3Explanation (Part A):
She was supposed to divide five both sides. However, she divided one side by five and multiplied five on the other side, which makes her answer incorrect. She got confused that if any side is divided by a number, the other side must be divided by that same number.Solution (Part B):
5y = 15=> 5y/5 = 15/5=> y = 3The correct answer must be 'y = 3'.
what is -2 x 3 i do not understand this and this is my last problem
Answer:
-6
Step-by-step explanation:
if they were both positive numbers, it would be 6. But when you multiply a negative by a positive, the answer is negative.
Answer:
-6
Step-by-step explanation:
When you multiply a positive number by another positive number, you will always get a positive number as your answer. Same thing for negative. If you multiply a negative by a negative, you will always get a positive. However, when you multiply a negative by a positive, you will always get a negative number.
Since you know this, you can multiply 2 by 3, which is 6. Because 2 is negative and 3 is positive, you know that the answer must be negative. Therefore, you add the negative symbol to 6, giving you -6.
I hope this isn't too confusing. Please let me know if you have any more questions. Good luck!

1. A ball is kicked up from a platform 36 feet above the ground. The height of
the ball h(t) above the ground (measured in feet) can be modeled by the
function h (t)
-3t2 + 12t + 36, where t represents the amount of time
(in seconds) since the ball was kicked. How long to the nearest second did it
take the ball to hit the ground?
-
seconds to hit the ground
Answer:6
Step-by-step explanation:
So when the ball hits the ground -3t^2+12t+36 must equal 0
So you can factor a -3 out
-3(t^2-4t-12)=0
Factor -3(t-6)(t+2)=0
T-6=0 t+2=0
T=6 t=Negative 2
And since time can’t be negative the answer is 6
