If x+2y=3 and xy=2 show that x³+8y³+9=0
Answers
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
PLZ HELP ME!!? you get 11 points!
Answers
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

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?
Answers
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

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.

Answers
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)

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.
Answers
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
