Hey there, Bulgogi!
The correct answer will be the first one since [I'm assuming] you know that to calculate the percentage of something, it's the amount of that something divided by the total amount but since only 30 students voted [12+18] multiplied by 100.
So, we are calculating the percentage on votes and 12 students voted for Candidate A so our Numerator will be 12 and our Denominator will be the total amount of student who voted, so 30 [or 12+18]
Once put into a fraction, we will get
![\frac{12}{12+18}](https://tex.z-dn.net/?f=%20%5Cfrac%7B12%7D%7B12%2B18%7D%20)
which would be equals to 2/5 or 0.4. Now we multiply by 100 and we get a total of 40% for Candidate A.
Thank you for using Brainly.
See you soon!
Answer:
f(x) = 3x² - 14x - 5
Step-by-step explanation:
multiply the factors: (x + 1/3)(x - 5)
x² - 5x + 1/3x - 5/3
x² -14/3x - 5/3
multiply by 3 to eliminate fractions:
3x² - 14x - 5
Not a solution, when plugging in (2,-3) into y=-6x+10 you get -2, When y equals -3. They are not the same.
