Answer:
y=-1/4x-4
Step-by-step explanation:
Answer:
f(- 2) = 13
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x)
f(- 2) = - (- 2)³ + 2(- 2)² + (- 2) - 1
= - (- 8) + 2(4) - 2 - 1 = 8 + 8 - 2 - 1 = 13
You have a total of 5 cans, because 1+3+1=5.
1 can is tomato soup.
So, the probability of selecting tomato soup randomly is 1/5.
Number of proper subsets = 2^number of elements- 1
= 2^n - 1
No of elements = 4
2^4-1 = 16-1 = 15
162=470m+b and 183=540m+b.
183-162=(540-470)m, 21=70m so m=0.30.
162=470×0.30+b=141+b, b=162-141=21
Therefore y=0.30m+21.
