Step-by-step explanation:
1 . x - 4y = -10
2x + y = -11
multiply the first equation with 2
2x - 8y = -20
-
2x + y = -11
===============
= 0 - 9y = -9
y = 1
x = -6

2.
a - 3b = 24

a + 2b = -16

= 0- 5b = 40
b = - 8
a = 0

Step-by-step explanation:
2:5, 4:10, 6:15
The proportion is solved and the number of games won by Ollie and Noelle over the weekend are 10 and 25 respectively
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
Ollie won 2 games for every 5 games that Noelle won
So , the proportion is 2 : 5
Now , when Noelle won 10 games , Ollie won 4 games
And , when Noelle won 15 games , Ollie won 6 games
when Noelle won 20 games , Ollie won 8 games
when Noelle won 25 games , Ollie won 10 games
So , the difference of their winnings is now = 15 games
Hence , the number of games won by Ollie and Noelle over the weekend are 10 and 25 respectively

Rayna is building a tapered staircase using wooden boards. The bottom stair is 3 1/2 ft wide, and the top stair is 2 1/6 ft wide. Each stair is 4 in. Shorter than the one below. What is the total length of wooden boards rayna needs for the stair tops, in feet? Enter your answer as an improper fraction.
Answers
Sum of an arithmetic sequence is defined by the formula,
[tex]T_n=\frac{n}{2}[2a+(n-1)d][/tex]
Total length of the wooden boards will be [tex]14\frac{1}{6}[/tex] feet.
It's given in the question,
Width of the bottom stair = [tex]3\frac{1}{2}[/tex] feetWidth of the top stair = [tex]2\frac{1}{6}[/tex] feetEach stair is 4 inch shorter than the one below.Since, 1 inch = [tex]\frac{1}{12}[/tex] feet
Therefore, [tex]4[/tex] inch = [tex]\frac{4}{12}[/tex] feet
= [tex]\frac{1}{3}[/tex] feet
So, each stair is [tex]\frac{1}{3}[/tex] feet shorter than one below.
Now the sequence formed will be,
[tex]\frac{7}{2},[\frac{7}{2}-\frac{1}{3}],[\frac{7}{2}-\frac{2}{3}],......\frac{13}{6}[/tex]
[tex]\frac{21}{6},\frac{19}{6},\frac{17}{6}....\frac{13}{6}[/tex]
It's an Arithmetic sequence with common difference 'd' = [tex]-\frac{1}{3}[/tex] and first term 'a' = [tex]\frac{7}{2}[/tex] and nth term [tex]T_n=\frac{13}{6}[/tex]
If there are 'n' stairs, expression for the for the top stair of the arithmetic sequence will be,
[tex]T_n=a+(n-1)d[/tex]
[tex]\frac{13}{6}=\frac{21}{6}+(n-1)(-\frac{1}{3})[/tex]
[tex]\frac{13}{6}-\frac{21}{6}=-(n-1)\frac{1}{3}[/tex]
[tex]\frac{8}{6}=(n-1)\frac{1}{3}[/tex]
[tex]\frac{4}{3}=(n-1)\frac{1}{3}[/tex]
[tex](n-1)=4[/tex]
[tex]n=5[/tex]
Therefore, there are 5 stairs.
Now total length of the wooden boards = Sum of 5 terms of the sequence
= [tex]\frac{n}{2}[2a+(n-1)(d)][/tex]
= [tex]\frac{5}{2}[2(\frac{21}{6})+(5-1)(-\frac{1}{3})][/tex]
= [tex]\frac{5}{2}[\frac{21}{3}-\frac{4}{3}][/tex]
= [tex]\frac{17}{3}\times \frac{5}{2}[/tex]
= [tex]\frac{85}{6}[/tex]
= [tex]14\frac{1}{6}[/tex] ft
Therefore, total length of the wooden boards will be [tex]14\frac{1}{6}[/tex] ft.

Answer:
Step-by-step explanation:
The revenue function is given to you, it's just not given in equation form. In equation form, the function is
R(p) = p(120 - 4p)
If we are looking for the number of tickets that causes the revenue to be $0, we replace R(p) with 0 and solve for p.
0 = p(120 - 4p). That means, by the Zero Product Property, that
p = 0 or 120 - 4p = 0 which gives us, when we solve each one of those equations, that
p = 0 or
120 = 4p and
p = 30. The reasoning is the bold statement up above.
The equation we would use to determine the number of tickets needed to sell for the revenue to be $600 will be
600 = p(120 - 4p)

Answer:
Hey
Step-by-step explanation:
Hey did you find the answers to this? i really need it. im desperate!
1. The market is said to be in disequilibrium because there is a shortage of apartments on the market
2. The equilibrium quantity of the good or service will decrease if demand decreases and supply decreases
3. The equilibrium price for this market is $20
4. It can be said that at a price level of $100 there is a a shortage of 0.4 million units
Equilibrium is the point at which quantity demanded equal quantity supplied
The price at this point is referred to as the equilibrium price.
Above equilibrium, there is a surplus - quantity supplied exceeds quantity demanded. As a result of the surplus, price would fall until equilibrium is reached.
Below equilibrium, there is a shortage - quantity demanded exceeds quantity supplied. As a result of the shortage, price would rise until equilibrium is reached.
A decrease in demand would lead to a leftward shift of the demand curve. As a result, quantity and price decreases. A decrease in supply would lead to a leftward shift of the supply curve. This leads to a decrease in quantity and an increase in price. Taking these two effect together, equilibrium quantity would decrease and there would be an indeterminate effect on equilibrium price
Equilibrium price is $20. This is because this is the price at which quantity demanded exceeds quantity supplied
There is a shortage because quantity supplied is less than quantity demanded

What is a Line Segment?A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.
The figure given below shows a line segment ST, where the length of line segment ST refers to the distance between its endpoints, S and T.
Given that M is the midpoint of ST
S______________M______________T
What is Midpoint?
A midpoint is defined as in the middle of the line connecting two points a position known as a midpoint. A location in the middle of a line connecting the two points that are equally far from both points is the midpoint.
The endpoints of ST are -15 and 25.
So the midpoint between S and T is given by,
⇒ M = (25 - 15)/2,
⇒ M = 10/2
⇒ M = 5
Hence, the coordinate of the midpoint M = 5

Answer:
x = [tex]\frac{5}{7}[/tex] , y = - [tex]\frac{3}{7}[/tex]
Step-by-step explanation:
Given 2 equal matrices then the corresponding elements in each matrix are equal, then
2x + y = 1 → (1)
x - 3y = 2 → (2)
Multiplying (1) by 3 and adding to (2) will eliminate y
6x + 3y = 3 → (3)
Add (2) and (3) term by term to eliminate y
7x + 0 = 5
7x = 5 ( divide both sides by 7 )
x = [tex]\frac{5}{7}[/tex]
Substitute this value into (1) and evaluate for y
[tex]\frac{10}{7}[/tex] + y = 1 ( subtract [tex]\frac{10}{7}[/tex] from both sides )
y = [tex]\frac{7}{7}[/tex] - [tex]\frac{10}{7}[/tex] = - [tex]\frac{3}{7}[/tex]
