Which expressions are equivalent to the given expression?
y-8y3x0x-2
Equivalent expressions are expressions that have equal values
The equivalent expressions of [tex]y^{-8}y^3x^0x^{-2}[/tex] are [tex]x^{-2}y^{-5}[/tex] and [tex]\frac{1}{x^2y^5}[/tex]
The expression is given as:
[tex]y^{-8}y^3x^0x^{-2}[/tex]
Express x^0 as 1
[tex]y^{-8}y^3x^0x^{-2} = y^{-8}y^3 \times 1 \times x^{-2}[/tex]
Apply law of indices
[tex]y^{-8}y^3x^0x^{-2} = y^{-8 + 3}\times x^{-2}[/tex]
[tex]y^{-8}y^3x^0x^{-2} = y^{-5}\times x^{-2}[/tex]
Remove the product sign (x)
[tex]y^{-8}y^3x^0x^{-2} = y^{-5}x^{-2}[/tex]
Rewrite as:
[tex]y^{-8}y^3x^0x^{-2} = x^{-2}y^{-5}[/tex]
Rewrite as positive exponents
[tex]y^{-8}y^3x^0x^{-2} = \frac{1}{x^2y^5}[/tex]
Hence, the equivalent expressions of [tex]y^{-8}y^3x^0x^{-2}[/tex] are [tex]x^{-2}y^{-5}[/tex] and [tex]\frac{1}{x^2y^5}[/tex]

A and B are complementary to each other. If m∠A = 26° + x and m∠B = 38° + x, what is the value of x?
A.13°
B.14°
C.58°
D.18°
Please don't reply just for the points, I really need help understanding these things, if possible please leave me an explanation on how you got this. P.S Complementary angles add up to 90 degrees
A. 13
Step-by-step explanation:
What we are given....
∠A = 26° + x
∠B = 38° + x
∠A and ∠B are complementary
If complementary angles add up to equal 90° and ∠A and ∠B are complementary to each other
Then 26 + x + 38 + x = 90
^ ( Note that we just created an equation that we can use to solve for x )
Now its just basic algebra
26 + x + 38 + x = 90
step 1 combine like terms
26 + 38 = 64
x + x = 2x
we now have 64 + 2x = 90
step 2 subtract 64 from each side
64 - 64 cancels out
90 - 64 = 26
we now have 26 = 2x
step 3 divide each side by 2
26 / 2 = 13
2x / 2 = x
we're left with x = 13
What is the diameter of a hemisphere with a volume of 5990in^3 to the nearest tenth of an inch?
Answer:28.4
Step-by-step explanation:
Delta Math
The diameter of the asked hemisphere is 28.38 in.
What is hemisphere?The half of a sphere is called a hemisphere.
Given that, a hemisphere with a volume of 5990 in³
Volume of a hemisphere = 2/3πr³
2/3πr³ = 5990
r³ = 5990x7x3/22x2
r³ = 125790/44
r³ = 2858.8636
r = 28.38

X= root (y-1/y+1) ( make “y” as subject. ) number 19
Answer:
y = (x² + 1) / (1 – x²)
Step-by-step explanation:
x = √[(y – 1)/(y + 1)]
We can make y the subject of the expression as shown below:
x = √[(y – 1)/(y + 1)]
Take the square of both side
x² = (y – 1) /(y + 1)
Cross multiply
x²(y + 1) = (y – 1)
Clear bracket
x²y + x² = y – 1
Rearrange
x² + 1 = y – x²y
Factorise
x² + 1 = y(1 – x²)
Divide both side by (1 – x²)
y = (x² + 1) / (1 – x²)
Alyssa can complete a job in 12 minutes. If Miranda helps her, they can complete the job in 9 minutes. How long would it take Miranda to complete the job by herself? (In minutes.) Rate of work problem
Answer:
36 minutes
Step-by-step explanation:
The key is to get the same amount of time for each.
9 * 12 = 108
At 12 minutes per job,
in 108 minutes Alyssa could do
108/12 = 9 jobs
At 9 minutes per job,
Together in 108 minutes they could do
108/9 = 12 jobs
--------------------------
In 108 minutes Mirada does
12 - 9 = 3 jobs
108/3 = 36 minutes per job

Step-by-step explanation:
A firefighter is on the fifth floor of an office building. She needs to throw a rope into the window on the seventh floor, 40 feet above her. If she throws the rope upward with an initial velocity of 36 ft/s, will the rope get to the window.
Answer:
no, it wont
Step-by-step explanation:
2g.h = v²
2(33)(40) = v²
2640=v²
v=√2640 = 51.38 ft/s
36 < 51.38
so, the rope will not get to the window
Find all real solutions of the equation (x-5)^2-4=0 real solutions=?
Answer:
x = 7
x = 3
Step-by-step explanation:
(x - 5)² - 4 = 0
Take the (x - 5)² and foil it. By doing that, you're going to set them both against each other to multiply. The squared part means that (x - 5) is being multiplied by itself. Like so:
(x - 5) (x - 5)
Multiply the x by the x, the x by the -5, the -5 by x, and the -5 by -5.
The x times x would be x². The x times -5 would be -5x. The -5 times x would be -5x. And the -5 and -5 would be 25.
To put it in an equation: x² - 5x - 5x + 25 - 4
Simply the equation: x² - 10x + 21
Now that it's a quadratic equation, we can factor. Looking at the final term, the 21, we can find factors of 21 that add up to -10, which would be -7 and -3. They both multiply to a positive 21 and add up to a -10.
Taking this new information, we can split the equation up like so: (x -7), (x - 3)
Set both equations equal to 0.
So: x - 7 = 0
Add seven to both sides.
x = 7
x - 3 = 0
Add three to both sides
x = 3
Final Answer: x = 3, x = 7, both are real solutions

The equations and graph below can be used to determine the number of each type of bead kesley purchased. Where x represents the number of round beads and y represents the number of oval beads. What are the numbers of round and oval beads Kelsey purchased?
Answer:
Lesley purchased 1 oval bead and 4 round beands.
Step-by-step explanation:
Given that Lesley purchased 5 beads at a total cost of 80 cents, and the round beads cost 15 cents each, and the oval beads cost 20 each, to determine what are the numbers of round and oval beads Kelsey purchased, the following calculation must be performed :
5 x 0.20 + 0 x 0.15 = 1
4 x 0.20 + 1 x 0.15 = 0.95
2 x 0.20 + 3 x 0.15 = 0.85
1 x 0.20 + 4 x 0.15 = 0.80
Therefore, Lesley purchased 1 oval bead and 4 round beands.
