-7/15.
You multiply the numerator and denominator to get -21/45. To simplify, divide each by the greatest common factor, which is three, to get -7/15.

the rational roots of a polynomial function f(x) can be written in the form p/q where p is a factor of the leading corfficient o

Lorico [155]

False.

The Rational Root theorem states that P is a factor of the constant term and q is a factor of the leading coefficient.

levacccp [35]

Answer:

B. 4/21

Step-by-step explanation:

⇒This question is on probability

⇒Number of boys=3

⇒Number of girls=4

⇒P(S)= 4+3=7

Probability for a girl to win is= 4/7

We have 3 awards a free movie ticket, a collectible poster, or a free popcorn

P(S)= 3

Probability of being awarded a free popcorn = 1/3

The probability that a girl will win free popcorn =

4/7 * 1/3 = 4/21

hope i helped and have a wonderful day

In a two-digit number the units digit is three less than the tens digit. If the digits are reversed, the sum of the reversed num

makvit [3.9K]

Answer:

74.

Step-by-step explanation:

Let the number be xy.

Then from the given data

x = y + 3..........(1)

The numerical value of xy is 10x + y so the second equation is

10x + y + 10y + x = 121

11x + 11y = 121 Simplifying:

x + y = 11

x = -y + 11 .........(2) Adding equations (1) and (2):

2x = 14

x = 7

and therefore y = 7 - 3 = 4.

Neporo4naja [7]

Answer:

$(a)\ V = \{(N,30),(R,37),(S,17)\}$

$(b)$

$Domain = \{N,R,S\}$

$Range = \{37,30,17\}$

Step-by-step explanation:

Given

$V(R) = 37,\ V(N) = 30,\ V(S) = 17$

Solving (a): Set of ordered pair

A function y = f(x) is represented as (x,y)

So, the ordered pair of V is:

$V = \{(R,37),(N,30),(S,17)\}$

Order the alphabets in increasing order

$V = \{(N,30),(R,37),(S,17)\}$

Solving (b): The domain and the range

In a function $\{(x_1,y_1),...,(x_n,y_n)\}$

The domain and the range are represented as:

$Domain = \{x_1,x_2....x_n\}$

$Range = \{y_1,y_2....y_n\}$

So, we have:

$Domain = \{N,R,S\}$

$Range = \{37,30,17\}$
