Answer:

5 9/14

Step-by-step explanation:

Let's add the whole numbers first to make the process simpler, 4+1=5. So 5 1/7 + 1/2 can be converted to 5 2/14 + 7/14, with a common denominator of 14. Add the numerators together, and you get 5 9/14.

Hope this helps! ;)

Step-by-step explanation:

Vertical angles are all start across from each other.

So:

∠3 and ∠6 are across from each other

∠2 and ∠5 are across from each other

∠1 and ∠4 are across from each other

The only option with at least two of the true statements above is C.

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]

Answer:

50 cents The red on the right end.

Step-by-step explanation:

Let the chocolate chip cookies = x

Let the jumbo popcorn = y

Julie

y + 2x = 5

Marvin

y + 4x = 6                  Subtract

-2x = - 1                     The y's disappear. You are left with 1 dollar (negative). Divide by - 2

-2x/-2 = - 1 / -2

x = 1/2

x  = 0.5 or 50c

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.

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.

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
