a would the compound inequality have infinite solutions if a = 4

x < 4 AND x > a.

if a = 4 and we use an "or" instead of the "and" we have:

x < 4 or x > 4.

This is:

"x is larger than 4 or smaller than 4."

Then the solution of this is all the real numbers except the value x = 4.

The set of solutions can be written as:

{xI x ∈ R  \ [4]}

Where this reads:

"x belongs to the set of the reals minus the number 4".

Or we also could write it as:

x ∈ (-∞, 4) ∪ (4, ∞)

Where we have two open ends in the "4" side, so the value x = 4 does not belong to that set.

The equation of the line from the given figure is y=-7.

We need to find the equation of the line from the given figure.

The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system. The numerous points which together form a line in the coordinate axis are represented as a set of variables x and y to form an algebraic equation, which is referred to as an equation of a line.

From the given figure, we can see that the line is passing through the point (0, -7).

The slope (m) of the line is 0.

Put m=0 and (0, -7) in y=mx+c and simplify.

That is, -7=c

Now, substitute c=-7 in y=mx+c.

Thus, y=-7

Therefore, the equation of the line from the given figure is y=-7.

The solution to the equation is x = -2 or x = 5

The equation is given as

3x^2-9x=30

Rewrite properly as

3x^2 - 9x = 30

Divide through by 3

So, the equation becomes

x^2 - 3x = 10

Rewrite the equation

So, the equation becomes

x^2 - 3x - 10 = 0

Expand the equation

So, the equation becomes

x^2  + 2x - 5x - 10 = 0

Factorize the equation

So, the equation becomes

x(x  + 2) - 5(x + 2) = 0

This gives

(x + 2)(x - 5) = 0

Evaluate

x = -2 or x = 5

The value of x is 13° and the value of y is 131°

From the question, we are to determine the values of x and y

From the given diagram, we can write that

(3x + 10)° + 90° + (2x + 15)° = 180°  (Sum of angles on a line segment)

Solve for x in the equation

(3x + 10)° + 90° + (2x + 15)° = 180°

3x° + 10° + 90° + 2x° + 15° = 180°

Collect like terms

3x° + 2x° = 180° - 10° - 90° - 15°

5x° = 65°

x = 65/5

x = 13°

Also

y + (3x + 10)°  = 180° (Sum of angles on a line segment)

Put the value of x into the equation

y + (3(13) + 10)°  = 180°

y + (39 + 10)°  = 180°

y + 49°  = 180°

y = 180° - 49°

y = 131°

Charlotte can obtain that which website generated more revenue by (A) revenue divided by the number of posts.

Revenue is the total amount generated without the expenses to run a business.

From the given data we can conclude that content is what the website posted.

∴ To obtain which website generated more revenue per amount of content we have to divide revenue by the number of posts.

Website A posted 110 contents and generated $30,000,

∴ Revenue per content is,

= (30000/110) dollars.

= 272.72 dollars.

Website B posted 200 contents and genarated $75,000 dollars.

If Tess and Alice are both on the swim team. Last practice, they each swam laps for the same amount of time, but Tess finished more laps. This weekend, they're swimming the same number of laps at a swim meet. The person that will likely finish first is: Tess.

Since Tess finished more laps first when she and Alice both swam laps at the same number of time, which in turn means that there is likelihood or tendency that Tess will finish first.

Based on this we can conclude that Tess swab faster that Alice and may likely finish the swam lap before Alice if the both swim the same number of laps.

Answer:

(a) x = 10

(b) y = 4

Step-by-step explanation:

For a line of the form y = mx + b, the slope is m, b is the y-intercept

A parallel line will have the same slope and a different y intercept

A perpendicular line has a slope = -1/m

But x = -4 is a line parallel to the y axis intercepting the x-axis at -4. So slope = ∞

Therefore here are equations for a parallel line and a perpendicular line

A parallel line will have the form x = k where k is a constant(positive or negative). So x = 10 is a line parallel to x = -4

A perpendicular line will be of the form y = 4 or y = -10 or whatever, i.e. without the x component. Such a line will be parallel to the x-axis so both lines are perpendicular

Regarding your questions

y = 4x + 3 has a slope of 4 and a y intersect of 3 so it will be a sloping line
x = 4 will be parallel, not perpendicular to x = -4

I have provided a graph which makes this explanation clearer. The dotted line is x = 4 and you can see it is parallel to x = -4

[tex]x-4~\geqslant~-1\implies x~\geqslant~-1+4\implies \boxed{x~\geqslant~3} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{multiplying both sides by -5}}{-5(x)\underset{\stackrel{\uparrow }{notice}}{~\leqslant~}-5(3)}\implies -5x~\leqslant~-15\implies -5x= \begin{cases} -15 ~~ \textit{greatest value}\\ -16,-17,-18...-\infty \end{cases}[/tex]

let's recall that for inequalities whenever we divide or multiply or exponentialize by a negative value, we must flip the inequality sign, notice, multiplying by -5, flipped it sideways.

Also let's recall that on the negative side of the number line, the closer to 0, the greater, thus -1 is much much greater than -1,000,000.

The probability that a person selected randomly from the survey group is not in statistics given they are in AQR is 0.75

The Venn diagram represents the given parameter

From the Venn diagram, we have the following values

n(not statistics and AQR) = 21

n(AQR) = 21 + 7

Evaluate the sum

n(AQR) = 28

The probability that a person selected randomly from the survey group is not in statistics given they are in AQR is then calculated as

P(not statistics | AQR) = n(not statistics and AQR)/n(AQR)

So, we have

P(not statistics | AQR) = 21/28

Evaluate the quotient

So, we have

P(not statistics | AQR) = 0.75

Answer:

  y = 35°

Step-by-step explanation:

Given one angle of a triangle is 75° and the other two are 'x' and 'y', you want to find the possible values of 'x' and 'y' when x = 2y.

The angle sum theorem and the given relation give rise to two equations:

  75 +x +y = 180

  x = 2y

Using the second equation to substitute for x in the first equation, we have ...

  75 +(2y) +y = 180

  3y = 105 . . . . . . . . . subtract 75 and simplify

  y = 105/3 = 35

  x = 2y = 2(35) = 70

The measures of angles x and y are 70° and 35°, respectively.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol.

We have been given that Machine Alpha uses 3000 batteries a day in the clocks it makes and Machine Delta uses 2500 batteries a day in the clocks it makes.

Machine Alpha = 3000b

Machine Delta = 2500b

Let b dollars represents costs of each battery.

        Rotation = 180° counterclockwise.

Note that when the point is rotated 180° counterclockwise then the coordinate of the image point will be

   (x , y ) = (-x , - y)

For the coordinates of the image first we translate the center to the origin that is

    (-3,0) = (-3+3,0) = (0,0)

Now we will do same for the point that is,

   (-4 , 1) = (-4+3 , 1) = (-1,1)

Now the points are (-1,1). Thus the image will be  

   (-1,1) = (-(-1), -1) = (1,-1)
