Find the slope (2, -7) and (5, -4)

1. The relationship as a function r = f(t) is: r = (9 - 2t)/9.

2. The numeric value at t = -9 is: f(-9) = 3.

3. The value of t for which f(t) = 5 is t = -18.

The relationship is given as follows:

9r + 2t = 9.

To write the relationship as a function of t, we have to isolate the variable r as a function of the variable t, hence:

9r = 9 - 2t

r = (9 - 2t)/9.

To find the numeric value at t = -9, we replace the lone instance of t in the relationship by -9, hence:

r = (9 - 2(-9))/9 = 27/9 = 3.

To find when f(t) = 5, we have to find t for which f(t) = 5, hence:

9r = 9 - 2t

2t = 9 - 9r

2t = 9 - 9(5)

2t = -36

t = -36/2

t = -18.

Equation for the given pair of lines which are perpendicular to each other and intersect at the point (-3 , -7 ) are :

( y + 7 ) = m₁ ( x + 3) and ( y + 7 ) = (-1 / m₁ )( x + 3 )

As given in the question,

Pair of equations that are perpendicular to each other and intersect at point ( -3 , -7 ) are as follow:

let us consider slope of perpendicular lines are m₁ and m₂.

Product of the slope of perpendicular lines = -1

⇒ m₁ × m₂ = -1

⇒ m₂ = -1 / m₁

Pair of perpendicular intersect at point ( -3 , -7 ) .

Required equation of perpendicular lines is given by :

For line 1:

( y - (-7)) / ( x - (-3) ) = m₁

⇒ y + 7 = m₁ (x+3)  

For line 2:

( y - (-7)) / ( x - (-3) ) = m₂

⇒ y + 7 =  m₂( x+ 3)

⇒  y + 7 =  -1 / m₁ ( x+ 3)

Therefore, equation for the given pair of lines which are perpendicular to each other and intersect at the point (-3 , -7 ) are :

( y + 7 ) = m₁ ( x + 3) and ( y + 7 ) = (-1 / m₁ )( x + 3 )

Answer:

The answer for no 7 is A. 24 in, for no 8 is C. 10 in, for no 9 is D. similar

Step-by-step explanation:

The answer for no 7 can be calculation as follows

Since both rectangles are similar, then the corresponding side are proportional, and it follows

[tex]\frac{\overline{KJ}}{\overline{AB}}=\frac{x}{\overline{AD}}[/tex]

[tex]\frac{48}{144}=\frac{x}{72}[/tex]

Where [tex]x[/tex] is the line segment [tex]\overline{MJ}[/tex]

Multiply both sides by [tex]72[/tex] to isolate [tex]x[/tex]

[tex]\frac{48}{144}\times 72=\frac{x}{72}\times 72[/tex]

[tex]\frac{48\times 72}{144}=x[/tex]

[tex]\frac{3456}{144}=x[/tex]

[tex]24=x[/tex]

Since the value of [tex]x[/tex] is [tex]24[/tex], then the length of [tex]\overline{MJ}[/tex] is [tex]24[/tex] in

The answer for no 8 can be calculation as follows

Since both rectangular frames are similar,  then the corresponding side are proportional, and it follows

[tex]\frac{w_2}{w_1}=\frac{x}{h_1}[/tex]

Where [tex]w_2[/tex] is the width of frame [tex]2[/tex], [tex]w_1[/tex] is the width of frame [tex]1[/tex], [tex]x[/tex] is the height of frame [tex]2[/tex], [tex]h_1[/tex] is the height of frame 1

Substitute [tex]8[/tex] for [tex]w_2[/tex], [tex]12[/tex] for [tex]w_1[/tex], [tex]15[/tex] for [tex]h_1[/tex]

[tex]\frac{8}{12}=\frac{x}{15}[/tex]

Multiply both sides by [tex]15[/tex] to isolate [tex]x[/tex]

[tex]\frac{8}{12}\times 15=\frac{x}{15}\times 15[/tex]

[tex]\frac{8\times 15}{12}=x[/tex]

[tex]\frac{120}{12}=x[/tex]

[tex]10=x[/tex]

Since the value of [tex]x[/tex] is [tex]10[/tex], then the height of  the second rectangular frame is [tex]10[/tex] in

The answer for no 9 can be evaluated as follows

The equation for the red graph is y = f(x/2).

We are given a graph. The graph shows two functions. A function connects an input to an output. It is similar to a machine with input and output. And the result is somehow connected to the input in some way. One of the functions is depicted by black lines. We need to find the equation of the function represented by the red lines.

We can see that the function represented by the red lines can be formed if the black lines are stretched horizontally. The black lines can be stretched horizontally by a factor of 2 to form the red lines. A function y = f(x) can be stretched horizontally by a factor of "k" as given below.

y = f(x/k)

Hence, the equation for the red graph is y = f(x/2).

The value of x for 5x + 1/3(3x+6) > 14 is x > 2

What are inequality equations in algebra ?
When you first begin learning algebra, the equals sign is used to denote that two items are, in fact, equal to one another. As an illustration, consider the equations 3 = 3, 5 = 3 + 2, apple = apple, pear = pear, etc. When compared, an inequality reveals two things: first, that the objects being compared are not equal, or at the very least, they are not always equal; and second, how they are uneven.

Consider the provided inequality.

5x + 1/3(3x+6) > 14

Distributive property:

a (b +c)= ab + ac

By the distributive property.

5x + 1/3 * 3x + 1/3 * 6 > 14

5x + x + 2 > 14

Add the like terms

6x + 2 > 14

Subtract 2 from both sides.

6x > 12

Divide both sides by 6.

6x/6 > 12/6

x > 2

Hence, value of x for the given inequality equation will be greater than 2 i.e, x > 2.

The outlier of the data is 14.16 gram

An outlier is a data point in statistics that dramatically deviates from other observations. An outlier may reflect measurement variability or it may point to an experimental error; the latter is occasionally removed from the data set. In statistical analyses, an outlier can result in significant issues.

Given:

Weights of the samples are 13 g, 14 g, 23 g, 11 g, 15 g, 14 g, 14 g, 12 g, 13 g, 15 g, 14 g, and 12 g.

So, the outlier is

= 13 x 2 + 14 x 4 + 12 x 2 + 11 + 15 x 2+ 13 / 12

= 170 gram /12

= 14.16 gram.

The probabilities, using the Poisson distribution, are given as follows:

a) Three customers in five minutes: 0.1805 = 18.05%.

b) Fewer than two customers in ten minutes: 0.0916 = 9.16%.

The probability mass function of the Poisson distribution is presented as follows:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

The parameters of the Poisson distribution are:

The mean is of two arrivals per five minutes, hence:

[tex]\mu = 2[/tex]

The probability of exactly three arrivals in five minutes is:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

[tex]P(X = 3) = \frac{e^{-2}2^{3}}{(3)!} = 0.1805[/tex]

For ten minutes, the mean is given as follows:

[tex]\mu = 2 \times 2 = 4[/tex]

The probability of fewer than two arrivals is:

P(X < 2) = P(X = 0) + P(X = 1).

In which:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-4}4^{0}}{(0)!} = 0.0183[/tex]

[tex]P(X = 1) = \frac{e^{-4}4^{1}}{(1)!} = 0.0733[/tex]

Then:

P(X < 2) = P(X = 0) + P(X = 1) = 0.0183 + 0.0733 = 0.0916 = 9.16%.

The solution for the linear equation:

x - (2/3)*x - (1/2) = (1/3) + (5/6)*x

Is x = -5/3

Is hard to understand what you wanted to write, but I assume that the linear equation that we need to solve is:

x - (2/3)*x - (1/2) = (1/3) + (5/6)*x

To solve this linear equation, we need to isolate the variable x in one of the sides of the equation

To do so, we move all the terms with "x" to the left side and the terms without to the right side:

x - (2/3)*x - (5/6)*x = 1/3 + 1/2

Now we solve this:

x - (4/6)x - (5/6)x = 2/6 + 3/6

x - (9/6)*x = 5/6

We can write the "1" in the first term as 6/6

(6/6)*x - (9/6)*x = 5/6

(-3/6)*x = 5/6

-3x = 5

x = 5/-3

x = -5/3
