Angle x is (2n + 12)°, and angle y is (3n + 18)° . Find the measure of angle x. Note: not drawn to scale.
A) 24°
B) 30°
C) 72°
D) 108

Answers

Answer 1
Answer: angles add to 180 since assume straighe line

x+y=180
x=2n+12
y=3n+18

2n+12+3n+18=180
5n+30=180
minus 30
5n=150
divide 5
n=30

sub back
x=2n+12
x=2(30)+12
x=60+12
x=72 degrees

C

Answers

it would be D because when you divide fractions, you multiply by the reciprocal of the fractions so 2/5 * 10/9. Then you simplify and get 4/9. Hope this helps!!!!!!!

Laura rents a movie for a flat fee of $2.00 plus an additional $0.50 for each night she keeps the movie. Choose the cost function that represents this scenario if x equals the number of nights Laura has the movie.a) c(x) = 2.00x + 0.50
b)c(x) = 2.00 + 0.50x
c) c(x) = 2.50x
d)c(x) = (2.00 + 0.5

Answers

b)c(x) = 2.00 + 0.50x

Remember that since 2.00 is the flat fee, so there is no variable. After that, though, there is the fee of .50 which is charged every day you have a movie.

say you had the movie rented out for five days
c(5)=2.00+.50(5)
=2.00+2.5
c(5)=4.5

Hope this helped!

Answer:

The cost function that represents this scenario is c(x) = 2 + 0.50x .

Option (b) is correct .

Step-by-step explanation:

As given

Laura rents a movie for a flat fee of $2.00 plus an additional $0.50 for each night she keeps the movie.

if x equals the number of nights Laura has the movie.


Than the cost function that represents this scenario .

c(x) =  Flat fee + Cost for  x equals the number of nights Laura has the movie.


c(x) = 2 + x × 0.50

c(x) = 2 + 0.50x

Therefore the cost function that represents this scenario is c (x) = 2 + 0.50x .

Option (b) is correct .

Which statement is true? All constants are of degree 0. All monomials are of degree 1. All binomials are of degree 1. All trinomials are of degree 3.

Answers

Among the statements only the First statement is true, All constants are of degree 0. Because monomials can have any degrees while binomials will always be in the 1 degree. Also, trinomials will always have a degree of 2.

Answer:

Option 1 is correct.

Step-by-step explanation:

Given the following statements we have to choose the true statement.

First option: All constants are of degree 0

The constant term of a polynomial is the term in which the variable does not appear i.e no variable include in that term i.e of degree 0.

Second option: All monomials are of degree 1

Monomials are the polynomials containing 1 term not necessarily of degree 1. Hence, the above statement not true.

Third option: All binomials are of degree 1

Binomials are the polynomials containing 2 term not necessarily of degree 1. Hence, the above statement not true.

Fourth option: All trinomials are of degree 3

Trinomials are the polynomials containing 3 terms not necessarily of degree 3. Hence, the above statement not true.

Hence, option 1 is correct.
