First you use the formula (-b/2a) to find the axis of symmetry(or the x value) and then you plug that into the equation to find the y value.

a = 2

b= -16

16/2(2)=16/4=4

(4, x )  so we have the x-value and now we plug 4 into the original equation

y=2(4)^2-16(4)+8

y=2(16)-64+8

y=32-64+8

y=-24

So the vertex is at (4,-24)

The simplified expression is [tex]\(338\sqrt{x} - 40\sqrt{2y}\),[/tex] combining like terms of square roots of variables.

To simplify the given expression, let's simplify each term separately:

1. [tex]\(2 \cdot 4\sqrt{16x}\)[/tex]

  - Simplify \(4\sqrt{16x}\): Since [tex]\(16x = (4 \cdot 4) \cdot x = 4^2 \cdot x\), the square root of \(16x\) is \(4\sqrt{x}\).[/tex]

  - Substitute this result into the expression:[tex]\(2 \cdot 4 \cdot 4\sqrt{x} = 32\sqrt{x}\).[/tex]

2. [tex]\(2 \cdot 4\sqrt{2y}\) - Simplify \(4\sqrt{2y}\): Since \(2y\) doesn't have a perfect square factor, we leave it as is. - Substitute this result into the expression: \(2 \cdot 4\sqrt{2y} = 8\sqrt{2y}\).[/tex]

3. [tex]\(34\sqrt{81x}\) - Simplify \(\sqrt{81x}\): Since \(81x = (9 \cdot 9) \cdot x = 9^2 \cdot x\), the square root of \(81x\) is \(9\sqrt{x}\).[/tex]

  - Substitute this result into the expression: [tex]\(34 \cdot 9\sqrt{x} = 306\sqrt{x}\).[/tex]

4. [tex]\(4 \cdot 4\sqrt{32y}\) - Simplify \(4\sqrt{32y}\): Since \(32y = (4 \cdot 8) \cdot y = 4^2 \cdot 8y\), the square root of \(32y\) is \(4\sqrt{8y}\). - Rewrite \(\sqrt{8y}\) as \(2\sqrt{2y}\) since \(8 = 4 \cdot 2\). - Substitute this result into the expression: \(4 \cdot 4 \cdot 2\sqrt{2y} = 32\sqrt{2y}\).[/tex]

Now, combine all the simplified terms:

[tex]\[ 32\sqrt{x} - 8\sqrt{2y} + 306\sqrt{x} - 32\sqrt{2y} \][/tex]

Combine like terms:

[tex]\[ (32\sqrt{x} + 306\sqrt{x}) - (8\sqrt{2y} + 32\sqrt{2y}) \][/tex]

[tex]\[ 338\sqrt{x} - 40\sqrt{2y} \][/tex]

Therefore, the simplified form of the expression is [tex]\(338\sqrt{x} - 40\sqrt{2y}\).[/tex]

The simplified form of the expression is 338√x - 72√2y, after applying the square roots to known perfect squares and combining like terms.

To simplify the expression, first apply the square root to known perfect squares and distribute the multiplication:

2(4√16x) becomes 2(4×4√x) because √16 = 4, so this part simplifies to 32√x.

2(4√2y) stays as is because √2y cannot be simplified further without more information about y, so this part is 8√2y.

34√81x can be simplified because √81 = 9, resulting in 34×9√x, which is 306√x.

4(4√32y) becomes 4(4×√16×√2y) because √32 = √16×√2, so this part simplifies to 64√2y.

Combining all the parts, we subtract the like terms:

32√x - 8√2y + 306√x - 64√2y

This simplifies further to 338√x - 72√2y

That is the final simplified expression.

m = (y2 -y1)/ (x2-x1)

m = (3-(-7))

Answer:

=59+108+81+x=360

=248+x=360

=112

Considering the nearest-degree measurements, angle x falls between 58.5 and 108.5 degrees, determined by adjusting the upper and lower bounds based on the provided angles in the diagram.

Given that the angles in the diagram are measured to the nearest degree, we can determine the upper and lower bounds of angle x using the provided angles: 59 degrees, 108 degrees, and 81 degrees.

To find the upper bound of angle x, we select the largest angle, which is 108 degrees. The upper bound is obtained by adding 0.5 degrees to this angle (since measurements are to the nearest degree). Therefore, the upper bound of angle x is 108 + 0.5 = 108.5 degrees.

For the lower bound, we choose the smallest angle, which is 59 degrees. The lower bound is found by subtracting 0.5 degrees from this angle. Thus, the lower bound of angle x is 59 - 0.5 = 58.5 degrees.

In conclusion, the measure of angle x lies between the lower bound of 58.5 degrees and the upper bound of 108.5 degrees.

Some number y has 7 subtracted off to get 15. We have y-7 = 15. To isolate y, we have to undo the "subtract 7" operation that happens to y. We have to add 7 to both sides.

y-7+7 = 15+7

Answer:

7 days because 15 times 7 =105 and if you add 30 to that you get 135.

Step-by-step explanation:

The Webb family rented the car for 7 days.

To find the number of days the Webb family rented the car, we can set up an equation using the given information. Let's say the number of days the car was rented is x. The total cost would then be $30 (one-time fee) plus $15 (daily fee) multiplied by x. This can be represented as the equation: 30 + 15x = 135. To solve for x, we need to isolate it by subtracting 30 from both sides: 15x = 105. Then, divide both sides by 15: x = 7. Therefore, the Webb family rented the car for 7 days.

So, this is a rate per person * number of people.

So,

$916 per person * 72 people = 65,952

The city pays $916 per year for health insurance for;

each of 72 municipal employees

So;

1 municipal employee gets ⇒ $916

72 employees get ⇒ How much?

Cross multiplying gives:

72/1 × $916 = $65,952

The total cost the city pays per year is $65,952.

Answer: [tex]4\frac{5}{12}\ feet[/tex]

Step-by-step explanation:

The height of Leon's older brother = [tex]4\frac{3}{4}[/tex] feet

[tex]=\frac{16+3}{4}=\frac{19}{4}[/tex] feet

Since, Leon is 1/3 foot shorter than his brother.

Then, the height of Leon = [tex]\frac{19}{4}-\frac{1}{3}[/tex]

First we need to make them like fractions by multiplying 3 on the numerator and denominator of the first fraction and 4 on the numerator and denominator of the second fraction.

Then, the height of Leon = [tex]\frac{57}{12}-\frac{4}{12}[/tex]

[tex]=\frac{57-4}{12}\\=\frac{53}{12}=4\frac{5}{12}[/tex] feet

Answer:

5 books

Step-by-step explanation:

Given that Toni carries upto 18 lbs in her backpack.

The maximum weight Toni can carry is 18 lbs.

Of these 18 lbs, already lunch of 1 lb and gym clothes of 2 lbs are included.

hence available for books is only the remaining 15 lbs.

Total weight in backpack= 18 lbs(Maximum)

Weight of lunch = 1 lb

Weight of her gym clothes = 2 lb

Hence maximum weight available for books = 18-(1+2) = 15 lbs

Weight of one book = 3 lbs.

No of books she can carry = 15/3 = 5 books
