Which ordered pair is a solution to the system? X>4 Y≥12

Step-by-step explanation:

Direct variation means    y = k x

when y = 2      x= 3

   2 =  k *3

   2/3 = k

so the variation becomes y = 2/3 x

            when x = 2

                     y = 2/3 (2)=   4/3

The explicit rule for the sequence 4, 3 2/3, 3 1/3, 3.... is f(n) = 4 - 1/3(n - 1)

From the question, we have the following parameters that can be used in our computation:

4, 3 2/3, 3 1/3, 3....

In the above sequence, we can see that 1/2 is subtracted from the previous term to get the new term

Take for instance

2nd = 4 - 1/3 = 3 2/3

3rd = 3 2/3 - 1/3 = 3 1/3

4th = 3 1/3 - 1/3 = 3

And so on

This means that

So, the explicit rule is

f(n) = a + (n - 1)d

This gives

f(n) = 4 - 1/3(n - 1)

Hence, the explicit formula is f(n) = 4 - 1/3(n - 1)

Answer:

The last option

[tex]r = \dfrac{14}{6\cos\theta - \sin\theta}[/tex]

Step-by-step explanation:

Given equation is 6x - y = 14

To convert an equation in rectangular(cartesian) form, f(x, y) to polar f(r, θ) we use the following information

x = rcosθ

y = rsinθ

Substituting for x and y in the original rectangular equation 6x - y = 14,

6(rcosθ) - rsinθ = 14

Factoring out r on the left side,
r(6cosθ - sinθ) = 14

which gives

[tex]r = \dfrac{14}{6\cos\theta - \sin\theta}[/tex]

Approximately, the amount of money, in cents, that Celine will save in 12 years is: B. 300

In this scenario, the years would be plotted on the x-axis (x-coordinate) of the scatter plot while the money (in cents) would be plotted on the y-axis (y-coordinate) of the scatter plot through the use of Microsoft Excel.

On the Microsoft Excel worksheet, you should right click on any data point on the scatter plot, select format trend line, and then tick the box to display an equation for the line of best fit (trend line) on the scatter plot.

From the scatter plot (see attachment) which models the relationship between the years and the money (in cents), an equation for the line of best fit is given by

y = 26.9x - 18.5

when x = 12, the amount of money, in cents, that Celine will save in 12 years is given by;

y = 26.9(12) - 18.5

The boat is moving at 48 mph while the current is moving at 9 mph in still water.

Let's use the letters "B" for the boat's speed in still water and "C" for the current's speed.

The boat's effective speed upstream is B - C because it is moving against the current.

Since the boat is moving downstream against the tide, its effective speed is equal to B plus C.

Based on the supplied data, we can construct the following two equations:

234 = 6(B - C)

342 = 6(B + C)

Making these equations simpler:

39 = B - C

57 = B + C

Now that we have added the two equations, we may solve for B and C:

39 + 57 = 2B

96 = 2B

B = 48

Therefore, the boat's speed in calm water is 48 mph.

To find C, we can rewrite one of the initial equations with this value as a substitute:

39 = 48 - C C = 9

Thus, the current is moving at a 9 mph velocity.

Therefore, the boat is moving at 48 mph while the current is moving at 9 mph in still water.

The formula for calculating the standard error is:

SE = μ ± Z(σ/√N)

Where:

σ = the standard deviation,

Z = the Z value for the percent confidence level desired.

We must find the Z value, at the 85% confidence level from a Cumulative Standardized Normal table for the 99% confidence level. This gives us the value of Z = 1.44

If the inverse function of f is the function g, then x = f(x) gives x = g(y). We just need to reverse the function.

An inverse function or an anti function is defined as a function, which can reverse into another function. In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by ‘f’ or ‘F’, then the inverse function is denoted by f-1 or F-1. One should not confuse (-1) with exponent or reciprocal here.

If f and g are inverse functions, then f(x) = y if and only if g(y) = x

The function is :

[tex]f(x) =\frac{-1}{25x^{2} },x < 0[/tex]

We have to find the inverse of the function.

The inverse, interchange the variables solve for y,

Now,

The direction angle of the vector with initial point (1, -1) and terminal point (7, 2) is approximately 26.57 degrees, found by calculating the arctangent of the ratio of the y and x components of the vector.

The direction angle of the vector v is the angle it makes with the positive x-axis, measured counterclockwise.

To find this angle, we need to calculate the difference between the y-coordinates and x-coordinates of the terminal and initial points of the vector, respectively. Then, we can use the arctangent function to find the angle.

Let's first find the components of the vector v

v = <7 - 1, 2 - (-1)> = <6, 3>

Now, we can find the direction angle as follows

θ = arctan(3/6)

θ = 0.4636 radians (in decimal form)

To convert this to degrees, we can multiply by 180/π

θ ≈ 26.57°

Therefore, the direction angle of the vector v is approximately 26.57 degrees.

m < L = 180 - (30 + 60)

m < L = 90º.

Answer:

-6x - 2y = 12

Step-by-step explanation:

Answer:The algebraic steps you have taken are incorrect, leading to an invalid conclusion. Let's go through each step and see where the mistake is made:

X = 1 (given)

X+X = 1+X (adding X to both sides)

2X = 1+X (combining like terms)

2X = X+1 (rearranging terms)

2X-2 = X+1-2 (subtracting 2 from both sides)

2X-2 = X-1 (simplifying)

2(x-1)/(x-1) = (x-1)/(x-1) (dividing both sides by x-1, note that x cannot be 1 as it would result in division by 0)

2 = 1 (canceling out the (x-1)/(x-1) on both sides)

The error lies in dividing both sides by (x-1) in step 7. Although (x-1) appears on both sides of the equation, it is not equal to zero as x cannot be 1 due to division by zero. Dividing by (x-1) effectively cancels it out, leading to the incorrect result of 2=1.
