which expression has a value of 6 when x=2 and y=4?

Answers

B
refer to picture for steps
Answer:6Verification:

Let's verify all the options to the question. Clue given: x = 2, y = 4

Option A:

(x² + 8) ÷ y - 2

=> (2² + 8) ÷ 4 - 2

=> (4 + 8) ÷ 4 - 2

=> 12 ÷ 4 - 2

=> 3 - 2

=> 1 ≠ 6

This answer does not equal 6.

Option B:

(x² + 8) ÷ (y - 2)

=> (2² + 8) ÷ (4 - 2)

=> (4 + 8) ÷ (4 - 2)

=> 12 ÷ 2

=> 6 = 6

This answer is correct as 6 = 6.

Option C:

x² + 8 ÷ (y - 2)

=> 2² + 8 ÷ (4 - 2)

=> 4 + 8 ÷ 2

=> 4 + 4

=> 8 ≠ 6

This answer does not equal 6.

Option D:

x² + 8 ÷ y - 2

=> 4 + 8 ÷ 4 - 2

=> 4 + 2 - 2

=> 4 ≠ 6

This answer does not equal 6.

So, after verifying all our options, we can conclude that Option B is correct. Therefore, Option B is the correct answer.

A rectangular community swimming pool is 31 2/3 meters long and 7 1/5 meters wide. The area around the swimming pool is covered with tiles. The area covered with tiles is 25% of the total area covered by the swimming pool. The total cost of the tiling is $712.50. What is the cost of the tiling per square meter?

Answers

Answer:

$12.50

Step-by-step explanation:

First, we find the area: 31 2/3 * 7 1/5 = 95/3 * 36/5 = 3,420/15 = 228 square meters. Then, we find the part that the tiles cover: 228 * 0.25 = 57 square meters. Now, we find the cost of the tiling per square meter by dividing the total cost by the total amount of tiling: $712.50 / 57 = $12.50. $12.50 will be your answer.

[tex]\sqrt[3]{488+24} \\[/tex]

Answers

Answer:

Step-by-step explanation:

First, add the values inside the radical

488+24 = 512

[tex]\sqrt[3]{512}[/tex] = x

This means that: [tex]x^{3}[/tex] = 512

Therefore, x must be equal to 8.

[tex]\sqrt[3]{512}[/tex] = 8

Brandon buys a radio for $48.81 in a state where the sales tax is 7%.
can someone pls help?

Answers

Answer:

$48.81 x 0.07 = 3.4167

$48.81 + $3.4167 = $52.2267

$52.23

Step-by-step explanation:

The shirt cost $48.81, and the sales tax is 7%. First convert the 7% into a decimal and you get 0.07, and then multiply that to the $48.81. You get left with $3.4167 and then add that to the $48.81 to get $52.2267. But, you have to shorten the numbers to make it look like money by simplifing. So the total is $52.23.

Answer:52.17

PLS help!

and explain

brainliest

Answers

Answer:

(2.5, -2.5)

Step-by-step explanation:

I think that's right. Quadrant IV is when (x, -y)

The point in Quadrant IV that is 4 units away from point (-1.5, -2.5) on the coordinate plane is (2.5, -6.5)

What is the coordinate plane?

A coordinate plane is a two-dimensional plane formed by the intersection of two number lines.

Given that, there is a point in quadrant IV that is 4 units away from point (-1.5, -2.5) on the coordinate plane.

If we have a coordinate point (x, -y) in quadrant 4, if the coordinate is 4 units away, the resulting coordinate will be expressed as (x+4, y-4)

(-1.5+4, -2.5-4) = (2.5, -6.5)

Hence, The asked point is, (2.5, -6.5)

Identify one point and the slope from the equation y + 4 = 1/3(x - 1)
Options:
m = 4 Point = (1/3, 1)

m = 1/3 Point = (1, -4)

m = 1/3 Point = (1, 4)

m = 1/3 Point = (-1, 4)

Answers

Answer:

m = 1/3 Point = (1, -4)

The slope is 1/3.

The point is 1,-4.

If you are wondering how I got the point, I just unsimplified the equation!

From y+4=1/3(x-1).

To y- -4=1/3(x-1).


The original formula is y-y1=m(x-x1). So we know where the y and the x is, and the slope.

[[Please Explain]] The equation y - 2/3 = -2 (x - 1/4) is written in point-slope form. What is the equation in slope-intercept form? ³
O y = -2x - 1/6
O y = -2x + 7/6
O y = -2x + 5/12
O y = -2x - 11/12

Answers

Slope-intercept form is just solving for y in point-slope form

y - 2/3 = -2 (x - 1/4)

First you distribute the -2 because it is the first order of operation

y - 2/3 = -2x + 1/2

Then you add 2/3 on both sides because we want to isolate y

y = -2x + 1/2 + 2/3

Then we combine like terms

y = -2x + 7/6
