Yes, the function would be negative
Answer:
3^x+12x-4
Step-by-step explanation:
(f+g)(x) = f(x) + g(x) = 3^x + 10x + 2x - 4 = 3^x + 12x - 4
Let: A = adult tickets; S = student tickets
a. 498 = 5A + 3S
118 = A + S
b. S = 118 - A
498 = 5A + 3(118 - A)
498 = 5A + 354 - 3A
498 - 354 = 2A
144 = 2A
A = 72
118 = S + A
118 = 72 + S
118 - 72 = S
S = 46
c. Therefore, there were 72 adult tickets and 46 student tickets sold.
If it is a 1000 dollar raffle then you would not win 500 at all
Answer:
3 quarts
Step-by-step explanation:
First, find how many quarts of antifreeze is in the mixture.
0.4 x 6 = 2.4
Now, make it into a fraction by putting the antifreeze amount over the rest so:
2.4/6
Now add + a at the end of the numerator and bottom to make:
2.4 + a/ 6 + a.
Now, turn the percentage you want to strengthen or weaken the mixture into a percentage. So, 3/5.
Now, make it an expression by adding = 3/5 at the end of the equation.
2.4 + a/ 6 + a = 3/5
Now, use cross multiplication.
12 + 5a = 18 + 3a
Now, solve the equation.
12 + 5a = 18 + 3a
-3a. -3a
12 + 2a = 18
-12. -12
2a = 6
/2. /2
a = 3.
Therefore, the answer is 3 quarts.
