y = 7 x is the situation's linear equation in two variables and 7 is Slope of line.

To determine a line's inclination or steepness, use the slope formula. By calculating the ratio of the change in the y-axis to the change in the x-axis, it may be used to calculate the slope of any line. A line's slope is determined by how its "y" coordinate changes in relation to how its "x" coordinate changes.

The faucet leakage rate is shown here to be 7 gallons per hour.

Since y gallons could leak in x hours , we have

Leakage rate is expressed as gallons per hour divided by the number of hours.

Given that our leakage was y gallons, and

The duration of the leaking is x hours, as well.

7 gallons per hour is the leakage rate, so we have;

Amount of gallons leaked = Gallons leaking per hour × Number of hours

The situation is represented by the linear equation =

y = 7 × x.

By comparing this with y=mx+c, Slope of line is 7

y = 7 x is the situation's linear equation in two variables and 7 is Slope of line.

Step-by-step explanation:

When you roll a 6-sided die, there are 6 possible outcomes:

1, 2, 3, 4, 5, 6

3 of the outcomes are even, and 3 of the outcomes are odd.

p(A) = p(even) = 3/6 = 1/2

p(Ac) = 1 - p(A) = 1 - 1/2 = 1/2

Answer: There are a total of 6 * 6 = 36 outcomes when two dice are thrown.

The outcomes that result in a product at most 6 are (1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (3, 1), (3, 2), (3, 3), (4, 1), and (5, 1).

Answer:

The vertex form equation of a parabola is y = a(x - h)^2 + k, where (h, k) is the vertex and a is a constant that determines the shape of the parabola.

To write the vertex form equation of each parabola, we need to find the values of a, h, and k for each equation.

A. y = x^2 + 4 To find a, we can compare the coefficients of x^2 in the given equation and the vertex form equation. We see that a = 1 in this case.

To find h and k, we can complete the square for the x-term in the given equation. We add and subtract (b/2a)^2, where b is the coefficient of x and a is the coefficient of x^2.

y = x^2 + 4 y = x^2 + 4 + (0/2)^2 - (0/2)^2 y = x^2 + 4 + 0 - 0 y = (x + 0)^2 + 4 - 0 y = (x + 0)^2 + 4

We see that h = -0 and k = 4 in this case. The vertex form equation is y = (x + 0)^2 + 4, or y = x^2 + 4.

B. y = (x - 2)^2 + 4 This equation is already in vertex form, so we can directly read the values of a, h, and k. We see that a = 1, h = 2, and k = 4 in this case. The vertex form equation is y = (x - 2)^2 + 4.

C. y = (x + 4)^2 - 1 This equation is also already in vertex form, so we can directly read the values of a, h, and k. We see that a = 1, h = -4, and k = -1 in this case. The vertex form equation is y = (x + 4)^2 - 1.

D. y = (x + 4)^2 - 2 This equation is also already in vertex form, so we can directly read the values of a, h, and k. We see that a = 1, h = -4, and k = -2 in this case. The vertex form equation is y = (x + 4)^2 - 2.

When the sum of 5 and y is greater than or equal to -19, the inequality is y ≥ - 24.

Brust's votes equaled 2 times the sum of Pitt's votes and 400:

The total number of votes received was 2012:

Solve for P by substitution:

Find B:

Answer:

a)   Total # of votes:   B + P = 2012

     Brust vs Pitt:   B = 2(P + 400)

b)   1608 = votes for Brust

      404 = votes for Pitt

      Brust won by 1204 votes

Step-by-step explanation:

Given variables:

Given information:

Create a system of linear equations using the given variable and information:

Substitute the second equation into the first equation and solve for P:

⇒ 2(P + 400) + P = 2012

⇒ 2P + 800 = 2012

⇒ 3P = 1212

⇒ P = 404

Substitute the found value of P into the first equation and solve for B:

⇒ B + 404 = 2012

⇒ B = 1608

Therefore:

To find how many votes Brust won by, subtract the total number of votes for Pitt from the total votes for Brust:

⇒ 1608 - 404 = 1204

Two angles are called complementary when their measures add up to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.

Complementary angles add up to 90°- example: 15° & 75° are complimentary

For example:

Suppose if one angle is x then the other angle will be 90° – x.

Now, to find the complement of 2x + 52°, subtract the given angle from 90 degrees.

90o –  (2x + 52o) =  90o – 2x – 52o  = -2x + 38o

The complement of 2x + 52o is 38o – 2x.

Supplementary angles add up to 180°- example: 50° & 130° are supplementary

if the two angles form a linear angle, such that, if one angle is x, then the other angle is 180° – x

Explanation:

Use the trigonometric ratio cosine.

Remember that [tex]\cos(x) = \dfrac{\textrm{adjacent}}{\textrm{hypotenuse}}[/tex].

So, we can construct the following equation using the given triangle:

[tex]\cos(23\textdegree)=\dfrac{11}{x}[/tex]

This code is calculating the number of "hits" in a list of "CIS" that match the specified true mean of 25,000. The loop iterates through each item in the list and if the value matches the true mean, the sample_hits counter is incremented by one. After the loop has finished iterating through the list, the sample_hits value should represent the number of times the true mean was found in the list.

Answer:

You can consider the area to be that of a trapezoid with parallel bases f(a) and f(4), and width (4-a). The area of that trapezoid is ...

 A = (1/2)(f(a) +f(4))(4 -a)

 = (1/2)((3a -1) +(3·4 -1))(4 -a)

 = (1/2)(3a +10)(4 -a)

We want this area to be 12, so we can substitute that value for A and solve for "a".

 12 = (1/2)(3a +10)(4 -a)

24 = (3a +10)(4 -a) = -3a² +2a +40

 3a² -2a -16 = 0 . . . . . . subtract the right side

 (3a -8)(a +2) = 0 . . . . . factor

To avoid consecutive b's, the string of b's must be divided into one or more groups of 1, 2, or 3 b's. There are a total of 5 + 1 = 6 possible places to insert the dividers to create these groups. For example, suppose we have a string of 7 b's and we insert dividers between the 3rd and 4th b's, and between the 5th and 6th b's. This would create the following groups of b's: bb|bb|b. In general, the number of possible ways to divide the string of b's into groups of 1, 2, or 3 b's is equal to the number of ways to insert 6 dividers into a string of 7 b's. This is equal to the number of ways to choose 6 of the 8 possible places to insert the dividers, which is equal to $\binom{8}{6} = 28$.

Since the 5 a's and the 1 c must be arranged in a specific order, there is only 1 way to arrange these letters. Therefore, the total number of words consisting of 5 letter a's, 7 letter b's, and 1 letter c is equal to $1 \times 28 = 28$.

Answer:

-----------------------------------------------

According to the question there are 7 'b' s  and we can't have them together. We assume more than two consecutive 'b' s contain two consecutive 'b' s and hence not considering any option of having 3, 4, 6 or 7 'b' s.

There is only one way to place 'b' s apart which leaves us with 6 gaps.

There are 5 + 1 = 6 other letters which is just the number to fill in the gaps between 7 'b' s.

We have only an option for 'c' to have any of the 6 gaps, it gives us 6 options and no other options for 'a' s.

Therefore in total we have 6 possible ways.

The system of inequalities that is represented by the graph is given as follows:

The system of linear inequalities is defined with linear functions, which have the slope-intercept format given as follows:

y = mx + b.

In which the parameters are given as follows:

For the upper bound of the inequality, we have that the linear function:

Then the upper bound of the inequality has the definition given by:

y ≤ -x + 1.

For the lower bound of the inequality, we have that the linear function:

Hence the lower bound of the inequality has the definition given by:

y ≥ -0.75x + 0.5.
