Simplify the expression:
The picture is down below
Answer:
[tex]\frac{4x^{21}}{y^{11}}[/tex]
Step-by-step explanation:
You are going to need to know two properties of exponents.
[tex]x^a * x^b = x^{a+b}\\\frac{x^a}{x^b}=x^{a-b}[/tex]
Also know that a*b = b*a, so youc an change the order of multiplication.
Since everything is being multiplied in the numerator, and there is only multiplication, it's actually super easy to start. Just multiply everything.
[tex]8x^9y^8(-2)x^5y^{-9} = -16x^{14}y^{-1}[/tex]
so now you have [tex]\frac{-16x^14y^{-1}}{-4x^{-7}y^6}[/tex]
Again, since the numerator and denominator only have multiplication you can divide part by part. so the number divides the number, the x term divides the term and the y term divides the y term
-16/-4 = 4
x^14 / x^-7 = x^21
y^-1 / y^6 = y^-7
So all together that makes[tex]4x^{21}y^{-7}[/tex]
The final step in simplifying is making all negative powers into fractions. Sometimes non whole numbers can be made into roots. Definitely make negative powers fractions though
[tex]\frac{4x^{21}}{y^{-7}}[/tex]
The sum of three numbers is 83. The first number is 8 more than the second. The third number is 3 times the second. What are the numbers?
Answer:
23, 15 and 45
Step-by-step explanation:
a+b+c = 83
a = b + 8
c = 3*b
(b+8) + b + 3*b = 83
5*b + 8 = 83
5*b = 75
b = 15
a = b + 8 = 15 + 8 = 23
c = 3*b = 3*15 = 45
Verification
a+b+c = 23 + 15 + 45 = 83; correct

Write
1 quadratic function in
vertex form whose graph
has
the vertex (1,2) and passes
through the point (3,10)
Answer:
y = 2 ( x − 1 ) ^ 2 + 2
Step-by-step explanation:
y = a ( x − h ) ^ 2 + k
where vertex is (h,k) = (1,2)
h=1, k=2
y = a ( x − 1 ) ^ 2 + 2
sub ( 3,10)
10 = a (3 - 1)^2 + 2
a=2
y = 2 ( x − 1 ) ^ 2 + 2
A function is a relationship between inputs where each input is related to exactly one output.
The quadratic function in vertex form is given by:
y = a(x - h)² + k
(h, k) = vertex
The quadratic function in vertex form is y = 2(x - 1)² + 2.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = x + 2 is a function.
We have,
Quadratic function in vertex form whose graph has the vertex (1,2) and passes through the point (3,10).
The quadratic function in vertex form is given by:
y = a(x - h)² + k
(h, k) = vertex
Now,
(h, k) = (1, 2)
Passes through (3, 10).
So,
10 = a(3 - 1)² + 2
10 = 4a + 2
8 = 4a
a = 2
Now,
The quadratic function in vertex form is y = 2(x - 1)² + 2
Thus,
The quadratic function in vertex form is y = 2(x - 1)² + 2.

if p(x)=x*2-1 and q(x)=5(x-1),which expression is equivalent to (p-q)(x)?
Answer:
[tex](p - q)(x) = (x -1) (x - 4)[/tex]
Step-by-step explanation:
Given
[tex]p(x) = x^2 - 1[/tex]
[tex]q(x) = 5(x - 1)[/tex]
Required
(p - q)(x)
This is represented as:
[tex](p - q)(x) = p(x) - q(x)[/tex]
[tex](p - q)(x) = x^2 - 1 - 5(x - 1)[/tex]
[tex](p - q)(x) = x^2 - 1 - 5x + 5[/tex]
Collec like terms
[tex](p - q)(x) = x^2 - 5x + 5 - 1[/tex]
[tex](p - q)(x) = x^2 - 5x + 4[/tex]
Expand
[tex](p - q)(x) = x^2 -4x - x + 4[/tex]
Factorize
[tex](p - q)(x) = x(x -4) - 1(x - 4)[/tex]
[tex](p - q)(x) = (x -1) (x - 4)[/tex]

If yall wanna send a paragraph to yo girl/boy here
Before I met you, I didn’t think love was for me. It was something other people had and felt. Something in movies and in TV shows. It felt more like a wish I had then something real. Now that I’m with you, love is so much more tangible. It’s something I can reach out and touch. It’s so much more than a wish or a hope (though it does give me hope, for so many things), it’s the very real, wonderful person I wake up to. The warm hand next to mine, the brush of hair against my cheek. I love you and because of that love, I love so much more than you. I love myself and the world in a way I never thought possible. You’ve made that possible for me. You’ve made everything possible. I just wanted to let you know how much I appreciate having you in my life. For helping me through the bad times and being there to help me celebrate the good times, I cherish all of the moments that we share together. There aren’t enough words in the dictionary for me to tell you how glad I am to have you in my life. I am so lucky to have you by my side. Everything you do for me never goes unnoticed. I don’t know what I did to deserve someone as wonderful as you, but I am eternally grateful to have your love, support, and affection. Thank you for being you, and for having me by your side.
