Answer:
20 movies ; $70
Step-by-step explanation:
Company 1:
Monthly charge = $40 ; additional = 1.5 per movie
Let number of movies = x ; t = cost
Equation 1:
y = 40 + 1.5x
Company 2:
Monthly charge = $30
Additional = $2 per movie
Equation 2:
y = 30 + 2x
1) for equation 1 = equation 2
40 + 1.5x = 30 + 2x
40 - 30 = 2x - 1.5x
10 = 0.5x
x = 10/0.5
x = 20
Hence, 20 movies
B.)
y = 30 + 2x
y = 30 + 2(20)
y = 30 + 40
y = $70

James and Willis are both painting a room. James could complete it in 6 hours by himself. Together they can complete the room in 2 hours. How long would it take Willis to paint the room by himself?
Answer: Willis will take 3 hours to paint the room by himself.
Step-by-step explanation:
Given: Time taken by James to complete job by himself = 6 hours
Let Time taken by Willis to complete job by himself = t hours
Together they take 2 hours.
[tex]\dfrac{1}{6}+\dfrac{1}{t}=\dfrac{1}{2}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{2}-\dfrac{1}{6}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{3-1}{6}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{2}{6}\\\\\Rightarrow\ t=\dfrac{6}{2}\\\\\Rightarrow\ t=3[/tex]
So, Willis will take 3 hours to paint the room by himself.

5x - 4y = 19
x + 2y = 8
Answer:
not sure what your question is but if youre trying to solve for the system of equations your awnser is (5,3/2)
Answer:
x= 5, y= 3/2
Step-by-step explanation:
5x -4y =19 (Equation 1)
x+ 2y=18 (Equation 2)
Using substitution method,
From equation(2),make x the subject of formula
x= 8-2y (Equation 3)
Substitute equation 3 into equation 1
5x -4y= 19
5(8-2y) -4y = 19
40 -10y -4y = 19
40-14y=19
Collect like terms
40-19=14y
21=14y
y= 21/14 = 3/2
Substitute for y in equation 3
x= 8 -2y
8- 2(3/2)
=8 -3
x = 5
please helppp ;-; how do you determine the end behavior of a function?
Answer:
End Behavior of a Function. The end behavior of a polynomial function is the behavior of the graph of f( x ) as x approaches positive infinity or negative infinity. The degree and the leading coefficient of a polynomial function determine the end behavior of the graph.
Step-by-step explanation:
We want to find the zeros of this polynomial: p(x)=(2x-1)(x+3)(x+1)(x-2) Plot all the zeros (xxx-intercepts) of the polynomial in the interactive graph.

If there are no Domain Restrictions, what is the domain?
Answer:
If there are no restrictions, the domain is all real numbers.
- infinity < x < infinity
Answer:
Step-by-step explanation:
Functions are a correspondence between two sets, called the domain and the range. When defining a function, you usually state what kind of numbers the domain (x) and range (f(x)) values can be. But even if you say they are real numbers, that doesn’t mean that all real numbers can be used for x. It also doesn’t mean that all real numbers can be function values, f(x). There may be restrictions on the domain and range. The restrictions partly depend on the type of function.
In this topic, all functions will be restricted to real number values. That is, only real numbers can be used in the domain, and only real numbers can be in the range.

Mandy buys 5.5 packs of organic milk from the neighborhood store. Each pack is priced at $3.96. How much does Mandy spend in all on his purchase?
Answer:
$21.78
Step-by-step explanation:
We know that each pack of milk costs $3.96, so if we buy 5.5 of these, we will have to pay $3.96 5.5 times. In other words, we must multiply 3.96 by 5.5:
3.96 * 5.5 = 21.78
Thus, Mandy spends $21.78 in all.
for any positive integer n, the sum of the first n positive integers equals n(n 1)/2. what is the sum of all the even integers between 99 and 301 ?
The sum of all the even integers between 99 and 301 is 20200
To find the sum of even integers between 99 and 301, we will use the arithmetic progressions(AP). The even numbers can be considered as an AP with common difference 2.
In this case, the first even integer will be 100 and the last even integer will be 300.
nth term of the AP = first term + (n-1) x common difference
⇒ 300 = 100 + (n-1) x 2
Therefore, n = (200 + 2 )/2 = 101
That is, there are 101 even integers between 99 and 301.
Sum of the 'n' terms in an AP = n/2 ( first term + last term)
= 101/2 (300+100)
= 20200
Thus sum of all the even integers between 99 and 301 = 20200

there are 8 elements in a set a, there are 5 elements in a set b, and 3 elements of those are shared both a and b. how many elements are in union of a and b?
There are 10 elements in the union of A and B.
What is the union of A and B?
The union of A and B will contain all of the elements found in either A or B or both sets. The union of sets is represented by the set notation. To find the union of two sets A and B, use the union B formula. Simply putting all of A and B's elements in one set and removing duplicates yields the union.So, set A has 8 elements and set B has 5 elements.
Both have 3 elements in common. So, 3 + (8 - 3) + (5 - 3) = 3 + 5 + 2 = 10Therefore, there are 10 elements in the union of A and B.

Answer:
5Step-by-step explanation:
The magnitude of the complex number is expressed as;
|z| = √x²+y²
Given the complex number z = 4i+3j, x = 4 and y = 3
Substitute
|z| = √x²+y²
|z| = √3²+4²
|z| = √9+16
|z| = √25
|z| =5
Hence the magnitude is 5
