not a solution

Step-by-step explanation:

we can just fill it in on both equations

-4(4)+3(1)=2

-16+3=2

-13=2

It doesn’t work for this equation so it’s not a solution

Hopes this helps please mark brainliest

Answer:

No

Step-by-step explanation:

For (4, 1 ) to be a solution then both equations must be true

substitute x = 4 and y = 1 into both equations

- 4(4) + 3(1) = - 16 + 3 = - 13 ≠ 2

3(4) - 9(1) = 12 - 9 = 3

Since both equations are not true then (4, 1 ) is not a solution of the system.

The slope of the given graph x^2 = ln (xy) at the point (1, e) is e

We have been given a graph x^2 = ln (xy) and a point (1, e)

Differentiate the given graph on both sides

d/dx x^2 = d/dx (ln (xy))

⇒ 2x = 1/xy × d/dx (xy)

⇒ 2x × xy = x.dy/dx + y.dx/dx

⇒ 2x^2y = x.dy/dx + y

⇒  2x^2y = x.dy/dx + y

⇒ 2x^2y - y = x.dy/dx

⇒ (2x^2y - y)/x = dy/dx  … (1)

The slope at the point (1, e)

m = dy/dx at x = 1, y = e

Substitute the values in Equation (1)

⇒ m = (2(1)^2 (e) - e)/1

⇒ m = (2e - e)/1

⇒ m = e/1

⇒ m = e

Hence, the slope of the given graph is e.

At b= 24 will complete the square in the expression x^2 + bx + 144.

What is perfect square trinomial?

A perfect square trinomial expression can be created by taking the binomial equation's square. If and only if a trinomial satisfying the criterion b^2 = 4ac has the form ax^2 + bx + c, it is said to be a perfect square. The formula for the perfect square trinomial is (ax)^2 + 2abx + b^2 = (ax + b)^2.

Consider the given expression

x^2 + bx + 144

For this type of expression [tex]b = 2\sqrt{c}[/tex] will complete the square.

Here, c = 144

√144 = 12

So, b√c = 2(12) = 24

The expression becomes,

x^2 + 24x + 144 = (x + 12)^2

This is the perfect square.

Hence, b = 24  will complete the square in the expression x^2 + bx + 144.

The sampling method used in this scenario is random Systematic random sampling

Systematic random sampling

Systematic sampling is a form of probability sampling technique in which sample members are chosen from a wider population using a defined, periodic interval but a random beginning point. By dividing the population size by the desired sample size, this interval, also known as the sampling interval, is computed.

If the periodic interval is predetermined and the starting point is random, systematic sampling is still regarded as random even though the sample population has been chosen in advance.

The vertical asymptote is x=2 and horizontal asymptote is y = 0

An asymptote is a straight line that constantly approaches a given curve but does not meet at any infinite distance. In other words, Asymptote is a line that a curve approaches as it moves towards infinity.

There are three types is asymptotes:

Horizontal asymptote , Vertical asymptote and oblique asymptote.

in the expression 1/x-2, the horizontal asymptote is y=0 since the power of x in the numerator is less than that of denominator.

And the vertical asymptote is found by equation the denominator to zero

The population of the country will be 513 million in 2016 with The exponential model A=384. 7e^0. 018t describes the​ population, A, of a country in​ millions, t years after 2003.

The exponential model represents the degrading failure process using an equation like: where Y = degradation, T = time, and A and B = parameters to be predicted using the regression approach using historical data. Exponentials are frequently utilized when the rate of change of a quantity is proportional to its beginning amount. Y represents exponential decay if the coefficient associated with b and/or d is negative. Y represents exponential growth if the coefficient is positive.

Here,

A = 384. 7e^0. 018t

513=384. 7e^0. 018t

513/384.7= e^0.018t

ln(513/384.7) = 0.018t

ln(513/384.7)/0.018 =t

The required equation of the line will be y = 2x + 6 which passes through the points (-2,10), (10 -14).

The slope of a line is defined as the gradient of the line.

Given that line passes through the points (-2,10), (10 -14)

Let the required line would be y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

x₁ = -2, y₁ = 10

x₂ = 10, y₂ = -14

⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

Substitute values in the equation, we get

⇒ y - 10 = (-14 - 10)/(10-(-2))[x -(-2)]

⇒ y - 10 = (-24)/(12 )[x +2]

⇒ y - 10 = -2(x +2)

⇒ y = -2x - 4 + 10

⇒ y = -2x + 6

Therefore, the equation of the line would be y = 2x + 6 which passes through the points (-2,10), (10 -14).

The constant of proportionality for each table are 5, 2/3, 4, 1/5, 3, 2 and 1/2 while that of the equations are 1/8, 1/3 and 3/2

The constant of proportionality is the ratio of the y value to the x value i.e.

constant of proportionality(k) = y/x

To find the constant of proportionality for each table, just pick any non-zero corresponding x and y values on the table and find the ratio:
Using constant of proportionality(k) = y/x

1.  y/x = 5/1 = 5

2.  y/x= 4/6 = 2/3

3. y/x = 2/0.5 = 4

4. y/x= 2/10 = 1/5

5. y/x = 9/3 = 3

6. y/x = 8/4 = 2

7.y/x = 6/12 = 1/2

For the equations, just rewrite the equations in order to make y/x the subject:

8. y =1/8 x

y/x = 1/8

9. 6y = 2x

y/x = 2/6 = 1/3

10. 4y = 6x

y/x = 6/4 = 3/2

There are 6984 inverse proportional relationships and the direct proportional relationships are 97/72.

Given that:

Kelly has 97 apples, and Jason has 72.

The relationship between two variables, X and Y, is directly proportional if it can be expressed in terms of Y/X = k or Y = Xk.

Y/X = k

Substitute the given X and Y values ​​and solve for k.

Suppose, Y = 97, X = 72

then k = 97/72

Distinguish a proportional relationship from other relations, including an inverse relationship (XY = k or Y = k/X).

An inverse proportional relationship is one in which two quantities vary inversely with respect to each other. We say that the variable Y changes inversely with X if

Y = k/X

Substitute the given X and Y values ​​and solve for k.

Suppose, Y = 97, X = 72

then k = 97 x 72

=> k = 6984

Answer:

Step-by-step explanation:

(a is in the file)

B. An add 3 inches to height would affect the surface area more than 3 inches to weight because if the same number was multiplied to 0.13 and 0.08… 0.13 would have the greater outcome.

c. a number more than 10 but less than 11 is 10.5

The height is 50 so plug those two numbers into the equation

10.5=0.08W+(0.13)50-1.03

10.5=0.08W+ 6.5-1.03

10.5=0.08W+5.47

Subtract 5.47 from both sides

5.3=0.08

Divide by 0.08 on both sides

= 62.87lbs in one possibility for the value of W

D. a number between 12 and 13 is 12.5

12.5= 0.08w+ 0.13H-1.03

Subtract 1.03 on both sides

11.47= 0.08w+ 0.13H

Divide 11.47 in 2 so that weight and height can be added up to equal 11.47 in the end

5.73=0.08   5.73=0.13
