Since it is 10 less and you are trying to find out your number, you add 10.
71+10= 81
So, your number is 81.
The <em><u>correct answer</u></em> is:
x³+x²+x+1.
Explanation:
First we write the polynomial out with all of the other powers of x, using 0 as their coefficients:
(1x⁴+0x³+0x²+0x-1)÷(x-1)
To perform synthetic division, we write the coefficients of the dividend in a row:
1 0 0 0 1
We take the 1 from x-1 and use it in the box. We then drop the first 1 from the row of coefficients down.
We multiply our 1 in the box by the 1 at the bottom; this is 1 and goes under the first 0 to the right of the 1 in the coefficients row. We now add this 0+1; this is 1 and goes at the bottom beside the other 1.
Multiply this by 1; this is 1 and goes under the second 0 from the left in the row of coefficients. Add this to the 0; this is 1 and goes at the bottom, to the right of the other two 1's.
Multiply this by 1; this is 1 and goes under the third and last 0 in the row of coefficients. Add this to the 0; this is 1 and goes at the bottom, to the right of the other three 1's.
Multiply this by 1; this is 1 and goes under the -1 in the row of coefficients. Add this to the -1; this is 0 and goes at the bottom, to the right of the four 1's. This 0 means there is no remainder and the quotient was evenly divided. It gives us
1 1 1 1 0
This means we have 1x³+1x²+1x+1 with no remainder.
Answer:
First you right the division as a fraction
1/5x=5
then mutiply both sides of the equation by 5
x=25

Answer:
B
Step-by-step explanation:
We can figure out the initial value and base of an exponential function if the function is written in the form 
where
a is the initial value, and
b is the base
<u>Note:</u> a ≠ 0 and b ≠ 1
Our equation given can be written in this form by writing it like 
Thus, this is an <em>exponential function</em>. The initial value is 1 and the base is 5.
The correct answer is B
