Answer:
(36,-30)
Step-by-step explanation:
y = -30
Solve for x
y = -x+6
-30 = -x+6
Subtract 6 from each side
-36 = -x
Multiply each side by -1

If 5x – 3y = 1 and
x - 2y = - 4, then xy = ? .
A 5

D 8
E 9
Answers
Answer:
[tex]6[/tex]
The answer is C:6
5x -3y=1......eq 1
x-2y=-4 ......eq2
From equation 2 too we can write
x = -4 + 2y ... put this x value on eq 1 so
5(-4+2y) - 3y = 1
-20 + 10y -3y=1
Or, 7y=21
So y=21/7=3
And put the value of y on equation 2
x -2 X 3 =-4
Or x= -4+6
So x=2 answer from question too we get value of x and y is 2,3 so
xy= 2X3=6 answer

0.3336
None of the above.
Answers
Answer:
0.2805
Step-by-step explanation:
Given that p = 20% = 0.2, n = 300.
The mean (μ) = np = 0.2 * 300 = 60
The standard deviation (σ) = [tex]\sqrt{np(1-p)}=\sqrt{300*0.2(1-0.2)}=6.93[/tex]
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma }[/tex]
For x = 57:
[tex]z=\frac{57-60}{6.93 } =-0.43[/tex]
For x = 62:
[tex]z=\frac{62-60}{6.93 } =0.29[/tex]
From the normal distribution table, P(57 < x < 62) = P(-0.43 < z < 0.29) = P(z < 0.29) - P(z < -0.43) = 0.6141 - 0.3336 = 0.2805
1. “Systems of Linear Equations”
American Airlines sold a certain number of tickets from Los Angeles to Hawaii. They charged $90
for flight x and the remaining tickets for $250 for flight y. If the airline sold 120 tickets and
collected a total of $27,600 from the sale of those tickets:
a) Set up the System of Linear Equations
b) How many tickets of each flight were sold?
c) How much money was made from each flight?
Answers
Answer:
Part A)
[tex]\begin{aligned} x+y&=120 \\ 90x+250y&=27600\end{aligned}[/tex]
Part B)
Flight X sold 15 tickets and Flight Y sold 105 tickets.
Part C)
Flight X made $1,350 and Flight Y made $26,250.
Step-by-step explanation:
Let the amount of tickets sold by Flight X be represented by x and the amount of tickets sold by Flight Y be represented by y.
Part A)
The airline sold 120 tickets in total. Hence:
[tex]x+y=120[/tex]
Each x ticket costs $90 and each y ticket costs 250. The total income was $27,600. Thus:
[tex]90x+250y=27600[/tex]
Our system of equations is:
[tex]\begin{aligned} x+y&=120 \\ 90x+250y&=27600\end{aligned}[/tex]
Part B)
Solve the system of equations. We can use substitution. From the first equation, subtract y from both sides:
[tex]x=120-y[/tex]
In the second equation, we can divide everything by 10 and substitute in x:
[tex]9(120-y)+25y=2760[/tex]
Simplify:
[tex]16y+1080=2760[/tex]
So:
[tex]y=105\text{ tickets}[/tex]
Using the equation above:
[tex]x=120-(105)=15\text{ tickets}[/tex]
Flight X sold 15 tickets and Flight Y sold 105 tickets.
Part C)
Since each ticket of Flight X sold for $90 and Flight X sold 15 tickets, Flight X made $1,350.
Then it follows that Flight Y made $26,250.

Answer:
y = 20 degree
Step-by-step explanation:
angle EOA = 5y (being vertically opposite angles)
angle COE + angle EOA + angle AOD = 180 degree (being linear pair)
2y + 5y + 2y = 180 degree
9y = 180
y = 180/9
y = 20 degree
Answer:
y = 20
Step-by-step explanation:
Angles COE and DOF are vertical angles and are congruent.
m<COE = m<DOF = 2y
<BOA is a straight angle and measures 180 degrees.
m<BOF + m<DOF + m<DOA = 180
5y + 2y + 2y = 180
9y = 180
y = 20

New value = 374.25 + Percentage increase
New value =

The wheely fast co. Makes custom skateboards for professional riders. They model their profit with the relation P=-2b^2 + 14b - 20, where b is the number of skateboards they produce(in thousands) and P is the company's profit in hundred thousands of dollars. When does wheely fast break even?
Answers
Answer:
The answer is below
Step-by-step explanation:
Breakeven point is the point of balance where their is neither a loss or a profit. At the breakeven point, the revenue gotten from the sell of goods is equal to the cost of production of the goods, hence the profit is zero.
Given the profit function:
P=-2b² + 14b - 20
At breakeven P = 0, hence:
0 = -2b² + 14b - 20
-2b² + 14b - 20 = 0
-2b² + 10b + 4b - 20 = 0
-2b (b - 5) + 4(b - 5) = 0
(b - 5)(-2b + 4) = 0
b - 5 = 0; or -2b + 4 = 0
b = 5; or b = 2
Since b is in thousands, hence the company breaks even when the number of skateboards produced is either 2000 or 5000
