we know that
The x-intercept is the value of the variable x when the value of the function is equal to zero
so
In the table we have
is a x-intercept, because
For 
the value of the function is equal to zero
is a x-intercept, because
For 
the value of the function is equal to zero
therefore
<u>the answer is</u>
the continuous function in the table has two x-intercepts
<span>Average profit from the sale of 1 piece of furniture = 3x + 1
Average number of pieces of furniture that can be made using current supply of raw materials = 3x - 1.
Therefore,
Average profit of total furniture = Average profit X Average total of furniture sold
= (3x + 1) X (3x - 1)
= 9x^2 - 1</span>
7^2 +6 ^2= 85
Square root of 85 = 9.219544457
Answer : 9.2
If the number is y then the inequality is
twice the difference of y and 7=2(y-7)
at most- 20=less than or equal to
2(y-7)≤-20
52.7 ÷ 4.25 = 12.4
Hope that helps ....
