Answer:
3*4=12
12-2=10
10*2=20
20+15=35
35*2=70
Step-by-step explanation:
In linear equation, the two inflection points of f(x) are at x = 1 or x = 4
We are aware that f(x) has a decreasing order if f'(x) 0 and a rising order if f'(x) > 0.
seen in the graph If f(x) is evidently growing on x (2, ) and decreasing on x ( 0,2) Since f(x) is dropping, if 0 x 2 is true, then f'(x) 0.
Since f(x) is rising, f'(x) > 0 if x > 2 is true.
Since f(X) is concave down, if 0 x 1 is true, then f"(x) 0 and vice versa.
Since f(X) is concave up, f"(x) > 0 and is true if 1 x 4
Given that f(X) has a concave downward shape, e) f"(x) 0 if x > 4 is true.
The two inflection points of f(x) are at x = 1 or x = 4.

Answer:
0 if 0≤x<1; T (d) f″(x)>0 if 14; T
Step-by-step explanation:
2 and the other is x= 2
10x /(divide) -2y
Answer:
-5x/y is the answer
Step-by-step explanation:
10x/-2y
Dividing by 2
=5x/-y
=-5x/y
I hope this will help you :)
Answer:
(-5x)/y
Step-by-step explanation:
I'm assuming you meant:
10x
---------
-2y
-5x
This reduces to ----------

Option B: Increase savings each month by $100 from their original plan
Answer:
Neither option A nor option B will allow them to meet their goal.
Step-by-step explanation:
Consider the provided information.
The Polleys want to put in a swimming pool next summer. They need to save $6,000 over 12 months in order to achieve this goal.
They set aside the same amount each month and after 7 months discovered they have saved $3,100. Now he left with 5 months (∴7+5=12 months)
Let x is the amount he was saving each month. He saved x amount for 7 months and after 7 months he has $3100.
He saved approximately $442.86 each month.
Option A Save the original amount each month but put the pool in one month later than originally planned.
That means the number of month he has now 5+1=6.
Now find how much he can save in 6 months if he save $442.86 per month.
6×442.86=2657.16
Now add his all savings as:
$3100+$2657.16=$5757.16
Thus, the option A will not allow him to meet his goal.
Now consider the option B) Increase savings each month by $100 from their original plan.
Previously he was saving $442.86 each month now increase this number by $100.
$442.86+$100=$542.86
In 5 months he can save:
5×542.86=$2714.3
Now add his all savings as:
$3100+$2714.3= 5814.3
Thus, the option B will not allow him to meet his goal.
