Associativ property
a(bc)=(ab)c
ability to move parenthaseese around
Answer:
B?
Step-by-step explanation:
As you may already be familiar, these functions f(x) and g(x) are piecewise. They consist of multiple functions with different domains.
1. For #1, the given input is f(0). Since 0≤1, you should use the first equation to solve. f(0)=3(0)-1 ➞ f(0)=-1
2. Continue to evaluate the given input for the domains given. 1≤1, therefore f(1)=3(1)-1➞f(1)=2
3. 5>1, therefore f(5)=1-2(5)➞f(5)=-9
4. -4≤1; f(-4)=3(-4)-1➞f(-4)=-13
5. -3<0<1; g(0)=2
6. -3≤-3; g(-3)=3(-3)-1➞g(-3)=-10
7. 1≥1; g(1)=-3(1)➞g(1)=-3
8. 3≥1; g(3)=-3(3)➞g(3)=-9
9. -5≤-3; g(-5)=3(-5)-1➞g(-5)=-16
Hope this helps! Good luck!
Answer:
The answer is $33.6
Step-by-step explanation:
Each small package costs him $2.80
3 small packages will cost him 3 x $2.80 = $8.4
Each large package costs him $3.60
7 large packages will cost 7 x $3.60 = $25.2
Cost to send 3 small packages and 7 large packages = $8.4 + $25.2
= $33.6
