When do you use a Vertex Form y=a(x – h)2 + k ? What information do you get from a Vertex Form?

Answers

Answer 1

Answer:

The vertex

Step-by-step explanation:

Vertex form shows you the vertex of a quadratic equation.

the y coordinate of the point is determined by k.

the x coordinate is determined by:

(x-h)=0

x-h=0

+h    +h

x=h

Quadrilateral ABCD is translated to get quadrilateral A’B’C’D’. Vertex A is at (-5, 2), and vertex A’ is at (2, -2). Quadrilateral ABCD is translated blank. If vertex B is at (-6, 5), then vertex B’ is at blank

Answers

Answer:

vertex B' is at (1, 1)

Step-by-step explanation:

Let us revise the rules of translation of a point

If the point (x, y) translated horizontally to the right by h units then its image is (x + h, y) ⇒ T (x, y) → (x + h, y)If the point (x, y) translated horizontally to the left by h units then its image is (x - h, y) ⇒ T (x, y) → (x - h, y)If the point (x, y) translated vertically up by k units then its image is (x, y + k)→ (x + h, y) ⇒ T (x, y) → (x, y + k)If the point (x, y) translated vertically down by k units then its image is (x, y - k) ⇒ T (x, y) → (x, y - k)

Let us use the rules to solve our question

Vertex A = (-5, 2)

Vertex A' = (2, -2)

→ The coordinates of the two points changed which means the

  quadrilateral is translated horizontally and vertically

∵ The x-coordinate of A = -5

∵ The x-coordinate of A' = 2

→ Which means it moves to the right, so use the first rule above

∴ the rule of translation is T (x, y) → (x + h, y)

∴ x → x + h

∵ x = -5 and x + h = 2

∴ -5 + h = 2

→ Add 5 to both sides

∴ -5 + 5 + h = 2 + 5

h = 7

∴ The quadrilateral is translated 7 units right

∵ The y-coordinate of A = 2

∵ The y-coordinate of A' = -2

→ Which means it moves down, so use the 4th rule above

∴ the rule of translation is T (x, y) → (x, y - k)

∴ y → y - k

∵ y = 2 and y - k = -2

∴ 2 - k = -2

→ Add K to both sides

∴ 2 - k + k = -2 + k

∴ 2 = -2 + k

→ Add 2 to both sides

∴ 2 + 2 = -2 + 2 + k

4 = k

The quadrilateral is translated 4 units down

→ Let us find B'

T (x, y) → (x + h, y - k) is the rule of translation

∵ B = (-6, 5)

∵ h = 7 and k = 4

∴ B' = (-6 + 7, 5 - 4)

∴ B' = (1, 1)

vertex B' is at (1, 1)

Quadrilateral ABCD is translated 7 units right and 4 units down. If vertex B is at (-6, 5), then vertex B′ is at (1, 1)

What does the word “flip” tell you to do in “keep change flip” for dividing fractions a) change the place of the numbers numerator and the denominator for the first fraction b) change the places of the numbers in the numerator and the denominator for the second fraction c) change the places of the numbers in the numerator and the denominator for both fractions d) change the ÷ between the fractions

Answers

Answer:

b) change the places of the numbers in the numerator and the denominator for the second fraction

Step-by-step explanation:

In the phrase "keep change flip":

You "keep" the first fraction.

"Change" the division sign into a multiplication sign.  

"Flip" (or switch) the places of the numerator and denominator in the second fraction.

Example:

[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{1}{3}[/tex]

[tex]\frac{1}{2}*\frac{3}{1}=\frac{3}{2}=1.5[/tex]

Answer:

x = 2.125 + 0.375y

Step-by-step explanation:

Simplifying

8x + -3y = 17

Solving

8x + -3y = 17

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation.

8x + -3y + 3y = 17 + 3y

Combine like terms: -3y + 3y = 0

8x + 0 = 17 + 3y

8x = 17 + 3y

Divide each side by '8'.

x = 2.125 + 0.375y

Simplifying

x = 2.125 + 0.375y

The value of  8/9/20 could be either 0.04 or 17.77.

What is a fraction?

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

In another word, the fraction is the division of the two numbers but the division is not wholly complete.

In another word, if we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

Given the fraction,8/9/20

Case 01)

(8/9)/20 = 0.888/20 = 0.044.

Case 02)

8/(9/20) = 8/0.45 = 17.77.

Hence "The value of  8/9/20 could be either 0.04 or 17.77".

if each side of the cube shown above has the same length as the measured side what is the approximate volume of the cube

Answers

Answer:

The measured side is not shown, so i will answer in a general way.

A cube is a 3-dimensional object with 6 square faces.

You know that all the sides of a square have the same length, then is the same for the cube.

To calculate the volume of a cube, we start with the area of the base.

The base is a square of sidelength L (Suppose that L is the length of the measured side)

The area of the base is:

A = L^2.

To find the volume, we must multiply the area of the base by the height of the fire (because the section of the base does not change).

And the height of the cube is also L.

Then the volume is:

V = L*a = L^3

(2,1)

Step-by-step explanation:

multiply by negative three on the first equation then solve

Answer:

(-2, 1)

Step-by-step explanation:

Given:

2x+8y=4...(1)

6x-y=-13...(2)

You would want to have an x or a y value that equals the same in both equations. In this case, we can multiply equation 1 by 3 so that both x's in each equation equal 6x.

(2x+8y=4) x 3...(1)

6x-y=-13...(2)

becomes...

6x+24y=12...(3)

6x-y=-13...(4)

As you can see here, both x's in this equation are equal.

Now we will be combining these equations together. Take the equal x values and make sure they will equal 0. You do that by either subtracting the entire equation or adding it. In this problem, we will be subtracting it because 6x-6x=0

(6x+24y=12) - (6x-y=-13) = 25y =25

Now that we can solve for y separately, 25y=25   y=1

To solve for x, just substitute y into one of the original equations (equations 1 or 2). For this problem, I'll use equation 1.

6x-y=-13

6x-1=-13

6x=-12

x=-2

20y = - 4x - 180 ( divide all terms by 20 )

The sugar sweet company is going to transfer its sugar to market. It will cost $4500 to rent trucks, and it will cost an additional $225 for each ton of sugar transported.

Let C Represent the total cost (in dollars), and let S represent the amount of sugar (in tons) transported. Write an equation relating C to S. Then use this equation to find a total cost to transport 14 tons of sugar.

Answers

Answer:

C=$7650

Step-by-step explanation:

Flat fee of 4500

S= 225x

x=14 tons of sugar

4500+225(14)=$7650 (C)

Equation:

C=4500+225(S)

Answer:

Total cost to transport 14 tons of sugar: $7650

Step-by-step explanation:

In the problem we are trying to find, C, the total cost to transport 14 tons of sugar.

$4500 to rent trucks

Additional $225 for each ton of sugar transported

C=4500+225(S)

We have our equation so now when begin to solve.

The problem gives us, S, the number of tons of sugar we are transporting, which is 14 tons.

So if it is an additional $225 for each ton of sugar then we would multiply 225 and 14. Which will look something like this:

C=4500+225(14)

Now we just simplify!

225(14)=3150

C=4500+3150

C=7650
