Solve the 2 equations then if : X and Y are positive then it is the first quad
if X is negative and Y is positive then it is in second quad
if X is negative and Y is negative then it is 3rd quad
if X is positive and Y is negative then it is the 4th quad
(look at the signs of numbers solved by the equation)
-2x would be the missing term.
Answer:
The first one, A
Step-by-step explanation:
DJ costs $300 in total.
For every student there is $5.
We want a profit of 1,500, so the total money earned from students attending subtracted by the costs of the DJ should be 1,500.
5n - 300 = 1,500
For the second one, it'll be the DJ giving you $300.
The last Two answers has an n where it's supposed to be money when n represents each student.
Answer:
c) 18 + 45m
Step-by-step explanation:
9(2+5m)
We multiply the 9 by each term inside the parentheses
9*2 + 9*5m
18+45m
Negative leading coefficient. Therefore it is the downward paeabola.
Discriminant of -40 therefore the parabola does not touch x-axis
so the answer is 1.
