Answer:
Option C
Step-by-step explanation:
![\sf log_w \ \dfrac{(x^{2}-6)^4}{\sqrt[3]{x^2+8} }=log_w \ (x^2-6)^4 - log_w(x^2+8)^{\frac{1}{3}}](https://tex.z-dn.net/?f=%5Csf%20log_w%20%5C%20%5Cdfrac%7B%28x%5E%7B2%7D-6%29%5E4%7D%7B%5Csqrt%5B3%5D%7Bx%5E2%2B8%7D%20%7D%3Dlog_w%20%5C%20%28x%5E2-6%29%5E4%20-%20log_w%28x%5E2%2B8%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D)
Answer:
f(x) = 8 + 0.25x
Step-by-step explanation:
The minimum cost is $8, for up to 4 pounds.
The added cost is ($0.25/oz)(x), where x is trhe ounces over 4 pounds
The total cost is the sum of these two:
f(x) = 8 + 0.25x
Answer: 1.3
Step-by-step explanation:
8 divided by 6 will equal 1.3 so each student will get 1.3
Answer:
35
Step-by-step explanation:
15+35=50
50=total number of students
50*0.3 = 15
50 - 15 = 35
35 students do not take the bus to school
Answer:
Round up all costs
Least expensive: $6
Most expensive: $13
Half (half of 12 people is 6) ordered $10 calculators so 6x10=$60
Other half
(6+13)/2= $9.5 round up to $10 so 6x10=$60
$60 + 60=$120 best estimate $125
