Answer:

2/3 x 5/8 = 5/8 x 2/3 is True

Step-by-step explanation:

Simplify the following: Left-Hand

2/3×5/8

2/3×5/8 = (2×5)/(3×8):

(2×5)/(3×8)

2/8 = 2/(2×4) = 1/4:

5/(3×4)

3×4 = 12:

Answer: 5/12

___________________________

Simplify the following: Right-Hand

5/8×2/3

5/8×2/3 = (5×2)/(8×3):

(5×2)/(8×3)

2/8 = 2/(2×4) = 1/4:

5/(4×3)

4×3 = 12:

Answer: 5/12

Answer:

[tex]S(h)=16h+46[/tex]

Step-by-step explanation:

We just need to substitute the variables here! You already have the equations so instead of [tex]x[/tex] for hours, we use [tex]h.[/tex] And since it's a function the result is not [tex]y[/tex] but rather [tex]S(h)[/tex].

So we get the answer of: [tex]S(h)=16h+46[/tex]

Answer:

false

Step-by-step explanation:

Answer:

True

Step-by-step explanation:

The ratio would be 1:2, which means for every unshaded part there's 2 shaded parts. Looking at the pie chart, we can tell that there are 2 unshaded and 4 shaded. This can mean there are 2:4 unshaded to shaded. Reduced, we get 1:2

Answer:

Step-by-step explanation:

Mean = Sum of all values/ total no of data

Explanation:

Combining like terms is commonly used to solve algebraic expressions. Like terms are those species or variables that are the same in any algebraic representation.

  Different mathematical operations can be performed on like species. We can add, divide, multiply, subtract, factorize, etc those terms.

Take for example;

   Solve;

        5x + 3  = 4x + 6

To solve this simply collect the like terms;

     5x  and 4x, 3 and 6 are like terms

       5x - 4x  = 6 - 3

        x  = 3

This is one way of solving problems by collecting like terms.

Step-by-step explanation:

(x²+2x+8)(x²-x+1)

distribute

x²(x²-x+1)

x^4-x³+x²

2x(x²-x+1)

2x³-2x²+2x

8(x²-x+1)

x^4-x³+x²+2x³-2x²+2x+8x²-8x+1

combine like terms

x^4+x³+7x²-6x+1

Answer:

what is the question

Step-by-step explanation:

The vertex of the given quadratic function is (-3, 0).

The vertex form of a quadratic equation or function is [tex]f(x)=a(x-h)^{2} +k[/tex].

Where,

(h, k ) is the vertex

And, a is constant.

According to the given question

We have a quadratic function

[tex]f(x) = x^{2} + 6x + 9[/tex]

The above function can be written as  

[tex]f(x) = x^{2} +2(3x) +9[/tex]

⇒[tex]f(x) = x^{2} + 2(3x) + (3^{2}) -(3)^{2} + 9[/tex]

⇒[tex]f(x) = (x+3)^{2} -9+9[/tex]

⇒[tex]f(x) = (x+3)^{2} + 0[/tex]

Comparing the above equation with the standard  vertex form of quadratic function we get

h = -3 and k = 0

Hence, the vertex of the given quadratic function is (-3, 0).

Thus, option A is correct.

Step-by-step explanation:

first you have to find the value of X.  So you take both expressions and make them equal to 180 degrees.  Then you solve for X. Once you do that X should equal 30. Then in place of X plug in 30 and solve. it should look like this (3(30)+22).  The answer is 112 degrees.

You could of also looked at your angle and saw it was an obtuse angle.  The only answer that was obtuse was 112 degrees.
