It sounds like the problem should read:
"An exclusive club for top students has to elect a new president and treasurer. There are 50 students in the club, and all are eligible for election. No person can have two jobs. How many different choices of officers are possible if:"
But then it trails off. It seems incomplete. Please update the problem with any missing information and/or instructions. Thank you.
Answer: y = -3x/7 + 26/7
Step-by-step explanation: Using the "slope-intercept" format, we can set up 2 equations, using the given points.
The format: y = mx + b, where m is the slope and b is the y-intercept (where x = 0)
To find m and b, we need 2 equations which we get using the 2 given points:
(-3,5):
5 = m(-3) + b (equation 1)
(4,2):
2 = m(4) + b (equation 2)
Subtract #2 from #1 to get:
3 = -7m
m = -3/7
Then, using equation 1, find b:
5 = (-3/7)*(-3) + b
b = 5 - 9/7 = 26/7
The equation is then:
y = -3x/7 + 26/7
Answer:
You can't change 3 18/15 to an proper fraction
srry :(
Step-by-step explanation:
Rewrite it as y=6x-7/5
Flip the x and y
x=6y-7/5
Solve
5x=6y-7
5x+7=6y
5/6x+7/6=y
f^-1(x)=5/6x+7/6
If you want to multiply 4 4/9 by 2 2/3, you can calculate this using the following steps:
4 4/9 * 2 2/3 = 40/9 * 8/3 = 320/27 = 11 23/27
The result is 11 23/27.
