Given:
The function is
To find:
The value of f(-1).
Solution:
We have,
Putting x=-1, we get
Therefore, the value of f(-1) is -12.
Answer: i think it's A or D
Step-by-step explanation:
70% = 70/100
divide 70 by 100
=0.7
Suppose the smallest odd integer is n, the next one is then n+2, and the third one is n+4
7n+2(n+4)=-91
7n+2n+8=-91
9n=-99
n=-11
so the three odd integers are -11,-9,-7
Answer: Explained in the step-by-step
Step-by-step explanation:
We want to isolate x, and remember, what we do to one side we do to the other:
(x+3) * 3 2/5 = 15 3/10
(x+3) * 3 2/5 divided by 3 2/5 = 15 3/10 divided by 3 2/5
x + 3 = 153/10 * 5/17
x + 3 = 765/170
x + 3 = 153/34
x + 3 = 4.5
x + 3 - 3 = 4.5 - 3
x = 1.5
Check:
(1.5+3) * 3 2/5 = 15 3/10
4.5 * 3 2/5 = 15 3/10
(3 2/5 = 3.4 and 15 3/10 = 15.3)
4.5 * 3.4 = 15.3
15.3 = 15.3
