Find x when y = 2 for the following equation: y = 6x + 8
PLS HELP ASAP

Answer: The lowest possible product would be -6724 given the numbers 82 and -82.

We can find this by setting the first number as x + 164. The other number would have to be simply x since it has to have a 164 difference.

Next we'll multiply the numbers together.

x(x+164)

x^2 + 164x

Now we want to minimize this as much as possible, so we'll find the vertex of this quadratic graph. You can do this by finding the x value as -b/2a, where b is the number attached to x and a is the number attached to x^2

-b/2a = -164/2(1) = -164/2 = -82

So we know one of the values is -82. We can plug that into the equation to find the second.

x + 164

-82 + 164

82

Choice D

Step-by-step explanation:

Choices A and B does not imply Dilation but Translation. Though Choice C implies Dilation, but it implies that \(\triangle J'K'L'\) is half the size of \(\triangle JKL\) but we can see that \(\triangle J'K'L'\) is larger than \(\triangle JKL\) so Choice D.

The probability of a driver encountering 7 potholes in a given mile of a highway with an average of 8 potholes per mile can be calculated using the Poisson distribution. The probability of encountering exactly 7 potholes is approximately 0.145.

The Poisson distribution is a statistical distribution that can be used to calculate the probability of a certain number of events occurring in a fixed interval of time or space, given the average rate of occurrence. In this case, the average rate of potholes per mile is 8. The Poisson distribution formula is:

P(X = x) = (e^(-λ) * λ^x) / x!

where P(X = x) is the probability of x events occurring, e is the base of the natural logarithm, λ is the average rate of occurrence, and x! is the factorial of x.

To calculate the probability of encountering exactly 7 potholes in one mile of the highway, we substitute λ = 8 and x = 7 into the formula:

P(X = 7) = (e^(-8) * 8^7) / 7!

≈ 0.145

Therefore, the probability of encountering exactly 7 potholes in one mile of the highway is approximately 0.145 or 14.5%

Answer:

x = 2

y = -1

Step-by-step explanation:

You can add together the equations so the x term cancels out:

  -3x + 5y = -11

+ (3x + 7y = -1)

The -3x and 3x cancel out, 5y and 7y add to 12y, and -11 and -1 add to -12:

12y = -12

Divide by 12 on both sides to get

y = -1

We can substitute this value into one of the equations to solve for x:

3x + 7y = -1

3x +7(-1) = -1

3x - 7 = -1

3x = 6

x = 2

Answer:

5/16 with bar notation is written as 0.3125, where the bar is placed over the digit "5" to indicate that it repeats infinitely. This notation is used to represent a repeating decimal, where the digit or group of digits after the bar repeats infinitely without terminating. In this case, the digit "5" repeats infinitely after the decimal point.

Answer:

The bar notation is used to indicate that a digit or a sequence of digits repeats indefinitely. To express 5/16 with a bar notation, we need to find the decimal equivalent of 5/16 and identify any repeating digits.

To convert 5/16 to a decimal, we can perform the division as follows:

0.3125

The decimal equivalent of 5/16 is 0.3125. Since there are no repeating digits, we cannot express it with a bar notation.

Answer: A

Step-by-step explanation:

Based on the graph, we know that it is negative if it is under the x-axis. It is also indicated by the negative labels.

A: correct

Looking at choice A, it says the interval is from -4<x<-2. This means we have to find x=-4 and x=-2. On the graph, that interval is below the x-axis, so it is negative.

B: incorrect

Looking at choice B, it says the interval is from -1<x<1. This means we have to find x=-1 and x=1. On the graph, that interval is above the x-axis, so it is positive, not negative.

C: incorrect

Looking at choice C, it says the interval is from 2<x<4. This means we have to find x=2 and x=4. On the graph, that interval is above the x-axis, so it is positive, not negative.

Therefore, A is the correct answer.

Therefore, it takes the airplane about 10 minutes to descend 4,000 feet.

Distance refers to the length or extent of space between two points or objects. It is a measure of how far apart two points are, and is typically measured in units such as meters, kilometers, miles, or feet. Distance is a scalar quantity, which means it only has a magnitude (i.e., a numerical value) and no direction associated with it. It is often used in calculations involving speed, time, and other physical quantities.

by the question.

We can use the rate of descent given in miles per minute to calculate the time it takes to descend a certain distance. First, let's convert 5/66 miles per minute to feet per minute:

5/66 miles per minute * 5280 feet per mile = 400 feet per minute

So, the airplane descends at a rate of 400 feet per minute. To find the time it takes to descend 4,000 feet, we can use the formula:

time = distance / rate

Plugging in the values we know:

time = 4000 feet / 400 feet per minute = 10 minutes

Step-by-step explanation:

If two predictor values have a very high linear correlation coefficient, both should be included in finding the multiple regression equation.

The exact value  of \(sin 2x\) is \(4√5/9.\)

Given that \(sec x = 3/2 and csc y = 3\)where x and y are in the 2x = 2 sin x quadrant, we need to find the exact value of sin 2x.

In the first quadrant, we have the following values of the trigonometric ratios:\(cos x = 2/3 and sin y = 3/5\)

Also, we know that sin \(2x = 2 sin x cos x.\)

Now, we need to find sin x.

Having sec x = 3/2, we can use the Pythagorean identity

\(^2x + 1 = sec^2xtan^2x + 1 = (3/2)^2tan^2x + 1 = 9/4tan^2x = 9/4 - 1 = 5/4tan x = ± √(5/4) = ± √5/2\)

As x is in the first quadrant, it lies between 0° and 90°.

Therefore, x cannot be negative.

Hence ,\(tan x = √5/2sin x = tan x cos x = √5/2 * 2/3 = √5/3\)

Now, we can find sin 2x by using the value of sin x and cos x derived above sin \(2x = 2 sin x cos xsin 2x = 2 (√5/3) (2/3)sin 2x = 4√5/9\)

Therefore, the exact value  of sin 2x is 4√5/9.

To find the y-coordinate of point P on the unit circle, given that its x-coordinate is 5/13, we can utilize the Pythagorean identity for points on the unit circle.

The Pythagorean identity states that for any point (x, y) on the unit circle, the following equation holds true:

x^2 + y^2 = 1

Since we are given the x-coordinate as 5/13, we can substitute this value into the equation and solve for y:

(5/13)^2 + y^2 = 1

25/169 + y^2 = 1

To isolate y^2, we subtract 25/169 from both sides:

y^2 = 1 - 25/169

y^2 = 169/169 - 25/169

y^2 = 144/169

Taking the square root of both sides, we find:

y = ±sqrt(144/169)

Since we are dealing with points on the unit circle, the y-coordinate represents the sine value. Therefore, the y-coordinate of point P is:

y = ±12/13

So, the y-coordinate of point P can be either 12/13 or -12/13.

Answer:

1936

Step-by-step explanation:

We can start by removing the center tile, because all four diagonals over lap on that tile. We'll add it back later. 88/4=22. which means there are 22 tiles per half, 44+1(the center tile) total tiles per side, which means there are a total of 1936 tiles.

AOPS ANSWER:

Suppose that we have a square with dimensions \($e \times e$\). The diagonals each have \($e$\\\) tiles. If \($e$\\\) is even, the number of yellow tiles is \($2e$\), because the \(2\) diagonals don't intersect. If \($e$\) is odd, then the number of yellow tiles is \($e+e-1=2e-1$\). (We have to subtract \(1\) because the center tile is counted \(2\) times). We know that there are \(89\) yellow tiles, which is an odd number, so \($89=2e-1$\). This implies that \($e = 45$\). So the dimensions of the floor are \($45 \times 45$\), or \(2025\\\) square units. Since all of the other tiles are gray, there are \($2025-89=\boxed{1936}$\) gray tiles.

1.1. \(\frac{dy}{dx} = -2cos(x)sinh(cos^{2}x)\)

1.2. \(\frac{dy}{dx} = \frac{2x-y}{y-x}\)

1.3. \(\frac{dy}{dx} = \frac{3x^{2} -2xy+5x}{2y-3x+1}\)

1.1. To find \(\frac{dy}{dx}\) for \(y = sinh^{-1}(cos^{2}x )\), we need to apply the chain rule. The derivative of \(sinh^{-1}(u)\) is \(\frac{1}{\sqrt{1+u^{2} } }\), and the derivative of \(cos^2(x)\) is \(-2cos(x)sin(x)\). Therefore, we have:

\(\frac{dy}{dx} = \frac{d}{dx}(sinh^{-1}(cos^{2}(x) ) )\\ = \frac{1}{\sqrt{1+cos^{4}(x) } }.\frac{d}{dx}(cos^{2}(x) )\\ = -2cos(x)sinh(cos^{2}(x) )\)

1.2. To find \(\frac{dy}{dx}\) for \(x^{2} +y^{2} = xy\), we can differentiate both sides of the equation implicitly.

Applying the product rule and chain rule, we get:

\(2x+2yy' = y+xy'\)

Rearranging the equation and solving for \(\frac{dy}{dx}\), we have:

\(\frac{dy}{dx} = \frac{2x-y}{y-x}\)

1.3. To find \(\frac{dy}{dx}\) for \(y = \frac{x^{3}-2x^{2} +5x }{2y-3x+1}\), we need to differentiate both sides of the equation implicitly. Applying the quotient rule and chain rule, we get:

\(\frac{2y-3x+1}{2}.\frac{dy}{dx} = \frac{(3x^{2} -4x+5)(2y-3x+1)-(x^{3}-2x^{2} +5x )(2-3y)}{(2y-3x+1)^{2} }\)

Simplifying the equation and solving for \(\frac{dy}{dx}\), we have:

\(\frac{dy}{dx} = \frac{3x^{2} -2xy+5x}{2y-3x+1}\)

The derivatives  \(\frac{dy}{dx}\) for the given equations are:

1.1. \(\frac{dy}{dx} = -2cos(x)sinh(cos^{2}x)\)

1.2. \(\frac{dy}{dx} = \frac{2x-y}{y-x}\)
