The answer to this would be 15. If one star is 5 point and Thursday has 4 stars that would be equal to 20. And Monday has 1 star so that’s five. 20 - 5 = 15.
Answer:
y = 3
Step-by-step explanation:
Substitute the given points into the function and solve for a and b
Using (2, 12)
12 = ab² → (1)
Using (5, 96)
96 = a
→ (2)
Divide (2) by (1)
=
, that is
b³ = 8 ( take the cube root of both sides )
b =
= 2
Substitute b = 2 into (1) and solve for a
12 = a2² = 4a ( divide both sides by 4 )
3 = a
Thus
y = 3
← is the exponential function
133 112
---- = -------
x 16
112x = 133 . 16
112x = 2128
x = 2128/112
x = 19
answer: x = 19
