Answer:
8
Step-by-step explanation:
Explanation
Step 1
solve for each factor:
set each factor equal to zero
so, we have 3 critical numbers
-3,-1 and 1
Step 2
now, let's make a table to evaluate each interval , (select a number from the interval)
b) (x+1)
c)(x-1)
Step 3
now, make th multiplication of the signs ( check the table in step 2)
so, we got
(-infi, -1) U (1, inf)
as we need that the product of the factors is greater than zero ( positive) , the solution is( set notation)
I hope this helps you
A) 1 and 2
That is the correct answer
Answer:
12.01 sticks of satay
Step-by-step explanation:
Let
Total satay bought = x
Eldest child ate = 1/6x
Youngest child ate = 0.25x
Total = 1/6x + 0.25x
= 0.167x + 0.25x
= 0.417x
Remaining satay = x - 0.417x
= 0.583x
The rest of the satay was shared equally between her other 2 children where each person ate 14 sticks of satay.
Her and her other two children = 3 people
Sticks of satay pee person = 14
Total sticks eaten by 3 people = 14 × 3
= 42 sticks
0.583x = 42
x = 42/0.583
= 72.04
x = 72.04 sticks
Total satay bought = x = 72.04 sticks
Eldest child ate = 1/6x
= 1/6 * 72.04
= 12.01 sticks of satay
