Answer:
y = 175. x = 300. Disney vacation is 300 sold. Cars sold were 175.
Step-by-step explanation:
They want to raise $80,000. There are a total of 475 tickets.
150x + 200y (Disney Vacation + Win a car) = 80,000
x + y = 475.
__
y=475-x
150x+200(475-x)=80000
150x+95,000-200x=80,000.
-50x + 95,000 = 80,000.
-50x = -15,000
x = 300.
Disney vacation is 300 sold.
300 + y = 475.
y = 175.
Cars sold were 175.
Additional Info:
I am 14 years old and I'm learning solving the systems by elimination and substitution, etc. Hope this is the correct answer.
Y = 3x - 7 . . . . . (1)
6x - 2y = 12 . . . (2)
Putting (1) into (2) gives
6x - 2(3x - 7) = 12
6x - 6x + 14 = 12
14 = 12
Therefore, there is no solution.
Answer:
O is greater than -4
Step-by-step explanation:
Answer:
f(x)= e^(2x)-4
change f(x) to y, switch _6 and y. solve for _5x_
The final function
f^(-1) (x)= ln(x+_7(8_)/(_(__)
