If x+2y=3 and xy=2 show that x³+8y³+9=0
Step-by-step explanation:
Given
x + 2y = 3 and xy = 2 show that x³ + 8y³ + 9 = 0Solution in steps:
(x + 2y)³ = 3³x³ + 3x²(2y) + 3x(2y)² + (2y)³ = 27x³ + 6x(xy) + 12y(xy) + 8y³ = 27x³ + 8y³ + 6(x + 2y)xy = 27 ⇒ Substitute valuesx³ + 8y³ + 6*3*2 = 27x³ + 8y³ + 36 - 27 = 0x³ + 8y³ + 9 = 0Done

Dave rents a limousine for his wife's birthday. The hourly rate is $80. They used the limo for 5 hours, plus Dave gave te=he driver a 20% tp. How much did he spend in total for the hourly charges plus tip?
Answer:
$480
Step-by-step explanation:
So first, you find how much he paid per hour which would be 80 * 5 = $400. Then, you have to add the tip in so you do $400 * 1.2 (or 120%) = $480.

For what value of x would these two equations have the same value? y = 45 + 20x y = 30 + 26x
Answer:
x=2.5 For both equations to be equal.
Step-by-step explanation:
45+20x=30+26x
Subtract 45 from each sides.
20x=-15+26x
Subtract 26x
-6x=-15
x=2.5
Check:
45+20(2.5)=30+26(2.5)
45+50=30+65

A sixth-grade science club needs $180 to pay for the tickets to a science museum. All tickets cost the same amount.
What could 180/15 mean in this context? Describe two interpretations of the expression. Then, find the quotient and explain what it means in each interpretation.
Answer: $12
Step-by-step explanation: Since all the tickets cost the same amount, then 180 which is the dividend means the total amount of money needed by the sixth grade science club
15 is the divisor and it represents the total number of tickets needed
The quotient is $12
So the cost of one ticket is $12.
does anyone know how to do this ?
Answer: D) 32
Step-by-step explanation:
The area of a parallelogram equals its base times its height. Substitute the base and area into this formula to solve for the height:
A=bh
40=(5)(h)
h=8
If ABCD is a parallelogram, opposite sides are parallel, so AB is parallel to DC. If AB is parallel to DC, EB is parallel to DC. Since EB is parallel to DC, quadrilateral EBCD has at least one pair of parallel sides, making it a trapezoid. The area of a trapezoid is equal to [tex]\frac{h(b_{1}+b_{2}) }{2}[/tex] where h is the height, [tex]b_{1}[/tex] is one base, and [tex]b_{2}[/tex] is the other base. Plug the necessary values into the formula:
A=[tex]\frac{h(b_{1}+b_{2}) }{2}[/tex]
[tex]b_{1} =AB-AE\\DC=AB\\b_{1} =DC-AE\\b_{1} =5-2\\b_{1} =3[/tex]
[tex]b_{2} =5[/tex]
h=8
A=[tex]\frac{8(3+5)}{2}[/tex]
A=32
The answer is D) 32.

The new iPhone is originally $1,200.00. For Memorial Day, they have a 35% discount. A sales tax of
8% was applied after the discount. What is the final price of the phone?
Original price of the iPhone = $1200.00
Percentage of discount given for memorial day = 35%
Cost of the iPhone after the discount :
[tex]= 1200 - 35\% \: \: of \: \: 1200[/tex]
[tex] = 1200 - \frac{35}{100} \times 1200[/tex]
[tex] = 1200 - \frac{42000}{100} [/tex]
[tex] = 1200 - 420[/tex]
[tex] =\color{hotpink} \$ \: 680[/tex]
Thus, the price of the iPhone after the discount = $680
Percentage of sales tax applied on the discounted price = 8%
Sales tax :
[tex]= 8\% \: \: of \: \: 1200[/tex]
[tex] = \frac{8}{100} \times 1200[/tex]
[tex] = \frac{9600}{100} [/tex]
[tex] = \color{hotpink}\$ \: 96[/tex]
Sales tax = $96
Price of iPhone after sales tax :
[tex] = 680 - 96[/tex]
[tex] =\bold\color{hotpink} \$ \: 584[/tex]
Therefore, the final price of the phone = $584

PLZ HELP ME!!? you get 11 points!
Answer:
y + 9 = 8(x - 2)
First, distribute the 8 across the parentheses.
y + 9 = 8x - 16
Now, combine the constants by subtracting 9 from both sides.
y = 8x - 25
Your equation is now in slope intercept form: y = mx + b
m is your slope.
In this case, m = 8; therefore, your slope is 8.
Answer:
8
Step-by-step explanation:
1. y+9=8(x-2)
2. y+9=8x-16
3. y=8x-25
8x=slope of 8
