Answer:
The answer is the 3rd one
Step-by-step explanation:
40 - 4 = 36
average = 36/9 = 4
answer
average number of members who joined the math club is 4 per month
Y= -2(x)+7 I'm pretty sure....
X^3 - 21x = -20add 20 to both sidesx^3 - 21 x + 20 = 0Rational Root Theorem:Factors of P (constant) 20 = 1, 2, 4, 5, 10, 20------------------------------- Factors of Q (leading Coefficient) = 1
Possible zeros (all + -) 1/1, 2/1, 4/1, 5/1, 10/1, 20/1
Of the choices given only the number 1 is a possible root.
