Answer:
34 members
Step-by-step explanation:
The math club at Emily's middle school has the number of members = 40
On Saturday only 85% of the members were attend the meeting.
Number of members who attend the Saturday meeting
= 85% of 40
= 0.85 × 40
= 34 members
34 members attend the Saturday meetings.
Use formula for difference of perfect cubes:
Consider expression You know that then
The quadratic trinomial cannot be factored anymore, so the expression has two factors and
Answer: correct choice is A.
12+(1/3)x=35
(1/3)x=23
x=7.6666
Answer:
x= 1, x= 4, and x= -3
Step-by-step explanation:
Use the possible combinations of factors of the constant term of the polynomial to find a first root. Try 1, -1, 2, -2, 3, -3, etc.
Notice in particular that x = 1 is a root (makes f(1) = 0):
So we know that x=1 is a root, and therefore, the binomial (x-1) must divide the original polynomial exactly.
As we perform the division, we find that the remainder of it is zero (perfect division) and the quotient is:
This is now a quadratic expression for which we can find its factor form:
From the factors we just found, we conclude that x intercepts (zeroes) of the original polynomial are those x-values for which each of the factors: (x-1), (x-4) and (x+3) give zero. That is, the values x= 1, x= 4, and x= -3. (these are the roots of the polynomial.
Mark these values on the number line as requested.
