X^2-x-11=-x-7
X^2-11=-7
X^2=4
X=2 (4 was reduced to 2 after the equation was square rooted)
Pls give brainliest so close to ranking up
Answer is C. Granted gas prices are fixed. if you buy 1 gallon.. price is x. if you buy 2 gallons, price is 2x. and so on. constant rate of change.
First, create a rule for this sequence.
Let a(1) be the first term (which here happens to be 1).
The next term, a(2), is twice the previous term, that is, twice 1, or 2.
a(3) = 2a(2) = 2(2) = 4
This is called a "recursive function."
The 3rd term is 4. The next, which is a(3) is 2*4, or 8.
Note that there's an alternative approach. The first term, a(1), is 1; the next is a(2) = a(1)*2^(2-1) = 1*2^1=2
the next is a(3) = 1*2^(3-1) = 1*2^2 = 4
So the rule is a(n) = a(1)*2^(n-1).
So a(8) is a(1)*2^(8-1) = 1*2^7 = 2^3*2^4 = 8(16) = 128
Answer:
1) Divisor is the factor of given dividend function.
2) the degree of divisor is less than equals to the degree of dividend function.
Step-by-step explanation:
Given that If you substitute a number into the function or if you use synthetic division and get a remainder of 0, then we have to list at least two conclusion from the result.
As we know, the remainder turns out to be 0 if divisor is the factor of the given dividend function which is also stated by the remainder and factors theorem.
Therefore, the two conclusion are
1) Divisor is the factor of given dividend function.
2) the degree of divisor is less than equals to the degree of dividend function.
