How many subsets does the set (1,2,3) have

Given data:

The given expression is f(x)= (-4x+8)/(x^2 -x-2).

The hole of the graph is x=2.

The expression for the vertical asymptode is,

The expression for the horizontal asymptode is,

There is no x-intercept, and y-intercept is,

Thus, the

A function can only have two horizontal asymptotes, hence the answer is no. By examining the degrees of the numerator and denominator, one can find the horizontal asymptote of a rational function.

If limxf(x)=L or limxf(x)=L, a function f(x) will have the horizontal asymptote y=L. Therefore, we simply calculate the function's limit as it approaches infinity and again as it approaches negative infinity to locate horizontal asymptotes. Based on the degree of the numerator, n, and the degree of the denominator, m, horizontal asymptotes adhere to three principles. The horizontal asymptote is y = 0 if n m. The horizontal asymptote is y = a/b if n = m. There is no horizontal asymptote if n > m. As x gets closer to 0, we say that f(xlimit )'s is infinite. A boundary or a limit is now a number.

Answer:

y= 2x + 9

Step-by-step explanation:

Number of biology book sold are 223.

Number of psychology books sold are 183.

In algebra, an equation is a declaration of equivalence that includes one or more variables or unknowable quantities.

Given Data

A textbook store sold a combined total of 392 biology and psychology textbooks in a week. the number of psychology textbooks sold was 48 less than the number of biology textbooks sold.

Let number of biology books sold be x

Let number of psychology books sold be (x- 48)

Total book sold = 392

392 = x + x - 48

392 + 48 = 2x

446 = 2x

x = 223

Shaded portion in single fraction is [tex]\frac{37}{10}[/tex] and mixed number is 3[tex]\frac{7}{10}[/tex] .

What is difference between fraction and mixed number?

Single fraction is represented as [tex]\frac{p}{q}[/tex]   form where p is numerator and q is denominator and value of q can't be zero. Example [tex]\frac{5}{9}[/tex] .

Mixed number contains two part one is an integer and other is fractional part. It is represented as N [tex]\frac{p}{q}[/tex]. Example  5[tex]\frac{1}{2}[/tex] .

According to figure, one shaded circle is equal to one unit and one shaded circle contain 10 sector.

There are three shaded circle and a circle with 7 sector shaded.

So, Total shaded area in single fraction = 1 + 1 + 1+ [tex]\frac{7}{10}[/tex] =   [tex]\frac{37}{10}[/tex]

and total shaded area in mixed number = 1 + 1 + 1 +  [tex]\frac{7}{10}[/tex] = 3 + [tex]\frac{7}{10}[/tex] = 3[tex]\frac{7}{10}[/tex] .

Answer:

No

Step-by-step explanation:

Using a graph typing in 9x and looking at the table, (2,1) is not on the table, so (2,1) is not a solution to 9x

Answer:

No

Step-by-step explanation:

to determine if (2, 1 ) is a solution, substitute the x- coordinate into the equation and if the result is equal to the y- coordinate then it is a solution.

y = 9x ( substitute x = 2 )

y = 9 × 2 = 18 ≠ 1

then (2, 1 ) is not a solution to the equation.

Riley hit 46 balls and Paul hit 29 balls at the driving range.

According to the question, let

Number of balls hit by Riley be x

Number of balls hit by Paul be y

Together Riley and Paul hit 75 balls

∴x+y=75       (1)

Riley hit 17 more balls than Paul

∴x= y + 17      (2)

Now we have to solve these simultaneous linear equations (1) and (2)

Replacing the value of x from equation (2) into equation (1) we get,

y+17+y=75

⇒2y + 17 = 75

⇒2y = 75 - 17

⇒2y = 58

⇒y = 58/2             (dividing both sides by 2)

⇒y = 29

∴No. of balls hit by Riley = x = y +17 = 29 + 17 = 46         (from equation (2))

Therefore, Riley hit 46 balls and Paul hit 29 balls at the driving range.

By applying a rotation of 90° clockwise to square ABCD, we have the following:

A rotation is a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise direction.

In Mathematics, rotating a point 90° about the origin in a clockwise or counterclockwise direction would produce a point that has the coordinates (y, -x).

By applying a rotation of 90° clockwise to square ABCD, the coordinate of the image of square A'B'C'D' is given by:

(x, y)                           →               (y, -x)

Points at A = (-3, 5)   →  Points at A' = (5, -(3)) = (5, -3)

Points at B = (-7, -2)   →  Points at B' = ((-2), -(-7)) = (-2, 7).

Points at C = (-8, 8)   →  Points at C' = (8, -(-8)) = (8, 8).

Points at D = (-4, 10)   →  Points at D' = (10, -(-4)) = (10, 4).

In order to determine the term values, the rate of increase in the number of videos that Violet has at the end of each week has to be determined.

Rate of increase in the number of videos can be determined by dividing the change in the number of videos per week by the change in the number of weeks.

Rate of increase = change in the number of videos / change in the number of weeks

(10 - 6) / (2 - 1)

4 / 1 = 4 videos per week

In ΔTUV, UV = 14, VT = 19, and TU = 9, The statement about the angles of ΔTUV that must be true is  [tex]m \angle U > m \angle T > \angle V[/tex] Option 5

This is further explained below.

Generally, A triangle's angle is a measurement of the length of the side that is perpendicular to it.

This indicates that if one of the sides is longer in length, then the measure of the angle opposite to it will also be longer.

The angles in the triangle TUV are denoted by the symbols T, U, and V.

The side that is UV, TV, and T U correspondingly is the side that is opposite to these angles.

The length of the opposing sides will immediately determine the measure of the angles, which will be directly proportionate to those angles.

since V T>U V>T U, the arrangement of angles will correspond to this as follows: [tex]m \angle U > m \angle T > \angle V[/tex] Option 5

To calculate the future value we need to use the compound formula:

where P is the principal, r is the interest rate in decimal form, n is the number of times the interest is compound in any given time t.

In this case we have that P=901, r=0.035 and since the interest is compound semiannually this means that n=2. Finally t=6. Plugging this values into the equation above we have that:

Therefore the future value would be $1109.53

The number of times Darlene mow her lawn before she needs more gasoline is equal to 18times.

As given in the question,

Total gasoline with Darlene is equal to 6 3/4 gallons

Convert mixed fraction into proper fraction:

6 3/4 = 27/4 gallons

Every time amount of gasoline used to mow her lawn = 3/ 8gallon

Number of times Darlene mow her lawn before she needs more gasoline

= (27 / 4) ÷ (3 /8)

= (27 /4) × (8/3)

= 18 times

Therefore, the number of times Darlene mow her lawn before she needs more gasoline is equal to 18times.
