23b because a cancels out
Step-by-step explanation:
What is the first equation?
Remember perpendicular lines have reciprocal slopes.
So if we have 1/2 we flip to fraction and sign becoming -2.
You then input the point to find the y-intercept.
The ratio of males to females is 1.4 : 1, so the fraction of the total that is made up of males is 1.4/(1.4 + 1) = 1.4/2.4 = 7/12.
There were (7/12)*475 ≈ 277 males at the party.
There were 475 - 277 = 198 females at the party.
Answer:
3n^2 - 5n - 28
Step-by-step explanation:
(n - 4)(3n + 7)
3n^2 + 7n - 12n - 28
3n^2 - 5n - 28
hope this hepls!!!
