Yes 1/4 is a rational number
Answer:
f(x) = 30 • 0.989x
Step-by-step explanation:
Given the data :
10 26.8
20 23.9
30 21.3
40 19
50 16.9
60 15.1
Using technology, the exponential model equation obtained by plotting the data is :
y = 30.068(0.989)^x
Based on the general exponential formula :
y = ab^x
y = predicted value
Initial value, a = 30.068
Rate = b = 0.989
The most appropriate model equation from the options given is :
f(x) = 30 • 0.989^x
Answer:
$21.55
Step-by-step explanation:
21.50 + 44.95 + 12 = $78.45
100 - 78.45= $21.55

Answer:
4(3x +8)
Step-by-step explanation:
You are being asked to factor 4 from each of the terms of the expression and use the distributive property to show the result.
12x +32
= 4(3x) +4(8)
= 4(3x +8)
The numbers that go in the boxes, left to right, are ...
4, 3, 8
Here is the solution for the eqns.
