1- 3(-2^2t)-7
2- 12+5=17
3- -10-6= -16
4- 2(-5^3)= -250
I can’t find the first one because of t
Answer:
The required function is:

Step-by-step explanation:
We have to represent the given scenario as an equation or function
Let x be the number of miles driven in a week
Let C(x) be the function of the number of miles driven
As it is given that charges are 150 per week, these charges are constant so they will be used as it is.
It is also given that the cost of car is 0.45 per mile so for x miles the cost will be:
0.45x
Combining both terms, we get

Hence,
The required function is:

2000 + 1500g ≤ 15000
1500g ≤ 15000 - 2000
1500g ≤ 13000
g ≤ 13000/1500
g ≤ 8 2/3
Therefore, the crane can safely lift a maximum of 8 2/3 cubic meters of gravel.
5/7 = non orange marbles
?/21 = chances to pick a non blue
21/7 = 3
5x 3 =15
15/21
