Answer: 4
Step-by-step explanation:
It is always increasing.
To find increasing and decreasing intervals, we need to find where our first derivative is greater than or less than zero. If our first derivative is positive, our original function is increasing and if g'(x) is negative, g(x) is decreasing.
*g(x) = y*
2x + 5 = y
2x = y - 5
x = (y - 5)/2
*Inverse*
g^-1(x) = (x-5)/2
Answer:
110 cups of lemonade
Step-by-step explanation:
165 oz ÷ 1.5 oz = 110 cups of lemonade

Answer:
256
Step-by-step explanation:
1st : 2nd = 8 : 7 -------- (1)
Number of 2nd year students = 224
Number of 1st year students = ?
From equ. 1,
1st : 2nd = 1st : 224 = 8 : 7
Therefore,
1st / 224 = 8 / 7
1st = 8 * 224 / 7
Therefore, Number of 1st year students = 256
