Base Number is unknown: a/?= x/100?

Answer:

[tex]g(x)=|-x+1|-2[/tex]

Step-by-step explanation:

When reflecting over the [tex]y[/tex] axis, [tex]f(x) \to f(-x)[/tex].

[tex]f(x)=|x+1|-2 \implies g(x)=|-x+1|-2[/tex]

The equation would be g(x) = |-x+1| -2 reflecting the function over the y-axis.

Reflection across the y-axis is defined as reflecting a point across they = x,  the x-coordinate, and y-coordinate places, the line y = -x is the coordinates (-x, y).

So reflected across the y-axis: f(x) → f(-x),

⇒ (x,y) → (-x , y)

The function is given in the question

f(x) = |x+1| -2

We know that the reflected across the y-axis: f(x) → f(-x),

⇒ (x,y) → (-x , y)

g(x) = f(-x)

g(x) = |-x+1| -2

Thus, the equation would be g(x) = |-x+1| -2 reflect the function over the y-axis.

Debemos tomar la integral definida de la diferencia entre las dos funciones en el intervalo dado.

Supongamos que queremos encontrar el area entre dos funciones f(x) y g(x) en un intervalo (a, b).

He should increase each dimension by 8 feet.

What is the area of a rectangle?

The area of the rectangle is the region enclosed by the perimeter of the rectangle and is equal to the product of length and width.

i.e. Area (A) = length(l) * width (w)

Given, a deck measurement is 12 feet by 10 feet

i.e. length (l) = 12 feet

width(w) = 10 feet

Area of deck (A) = 12*10 = 120 square feet

Let 'x' be the increased dimensions then,

new length = (12 + x) feet

new width = (10+x) feet

And, area of new dimensions = 3*120 = 360 square feet

So,  [tex](12 + x)*(10+x) = 360[/tex]

or, [tex]120+12x + 10x + x^{2} =360[/tex]

or, [tex]x^{2}+ 22x+120-360=0[/tex]

or, [tex]x^{2}+ 22x-240=0[/tex]

or, [tex]x(x+30)-8(x+30)=0[/tex]

or, [tex](x+30)(x-8)=0[/tex]

Answer: B

Step-by-step explanation:

The required equation of the line is 22x - 18.

A linear equation is defined as an equation in which the highest power of the variable is always one.

We take the two points (2, 26) and (5, 92) in the given table.

Let the required equation of the line is

⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

x₁ = 2, y₁ = 26

x₂ = 5, y₂ = 92

Substitute values in the equation, we get

y - 26 = (92-26/5-2)(x - 2)

y - 26 = 66/3(x - 2)

y = 22(x - 2) + 26

y = 22x - 44 + 26

y = 22x - 18

Therefore, the required equation of the line is 22x - 18.

Step-by-step explanation:

1. First things first, the binomial tells us the zeroes.

[tex] - (x - 2) {}^{2} = 0[/tex]

[tex](x - 2) {}^{2} = 0[/tex]

[tex]x - 2 = 0[/tex]

[tex]x = 2[/tex]

This root has a multiplicity of 2, so this root will "bounces off the x axis"

[tex](x + 4) = 0[/tex]

[tex]x = - 4[/tex]

Our x intercepts are

2 and -4

This root has a multiplicty of 1, so it will cross thorough the x axis.

Our leading degree is odd and we have a negative leading coefficient so

as x approaches ♾️, f(x) approaches negative ♾️

and as x approaches negative ♾️, f(x) approaches ♾️.

Our y intercept can be found by letting x=0,

so

[tex] - (0 - 2) {}^{2} (0 + 4) = - ( - 2) {}^{2} (0 + 4) = - (4)(4) = - 16[/tex]

So our y intercept is -16.

For Rational Functions, if the numerator and denominator share the same factor they are considered a removable discontinuity or hole.

Set it equal to 0.

[tex]x + 5 = 0[/tex]

[tex]x = - 5[/tex]

So we have a hole at x=-5.

Next, simplify the fraction.

[tex] \frac{x - 4}{x - 6} [/tex]

Now, plug in -5

[tex] \frac{ - 5 - 4}{ - 5 - 6} = \frac{ - 9}{ - 11} = \frac{9}{11} [/tex]

So we have a hole at (-5,9/11).

To find y intercept, let x=0,

[tex] \frac{0 - 4}{0 - 6} = \frac{2}{3} [/tex]

To find Vertical Asymptote, set denominator equal to 0

[tex]x - 6 = 0[/tex]

[tex]x = 6[/tex]

Draw a vertical dotted line at x=6

To find HA, this is the only case since the numerator and denominator has the same degree.

So using the leading coefficients, divide the numerator leading coefficient/ denominator leading coefficient.

The leading coefficient for both is 1 so

[tex]ha = \frac{1}{1} [/tex]

So our HA is y=1.

Draw a horizon tal dotted line at y=1

We have no slope asymptote.

The graph is above.

Part 3:

(3x-1)(2x+1)>0

[tex]3x - 1 = 0[/tex]

[tex]3x = 1[/tex]

[tex]x = \frac{1}{3} [/tex]

[tex]2x + 1 = 0[/tex]

[tex]2x = - 1[/tex]

[tex]x = - \frac{1}{2} [/tex]

We have three possible regions, when x is positive

Pick a random number less than -1/2 and plug it in the inequality to see if it true.

Let use -1

[tex](3( - 1) - 1)(2( - 1) + 1) = ( - 4)( - 1) = 4[/tex]

Since 4>0, Whenever x is less than -1/2, the function is positive (greater than zero)

Let's try the next region.

Let use 0

[tex](3(0) - 1)(2(0) + 1) = ( - 1)(1) = - 1[/tex]

So this solution won't work

Let try the next region, let use 1.

[tex](3(1) - 1)(2(1) + 1) = (2)(3) = 6[/tex]

Since 6>0, Whenever x is greater than 1/3, the function is positive(greater than zero).

Our answer is

(-oo,-1/2) U (1/3,oo).

Part 4:

We know x cannot be -2 because

[tex]x + 2 = 0[/tex]

[tex]x = - 2[/tex]

So -2 can not be in our answer.

[tex] \frac{x - 1}{x + 2} \leqslant 2[/tex]

[tex]x - 1 \leqslant 2(x + 2)[/tex]

[tex]x - 1 \leqslant 2x + 4[/tex]

[tex] - 5 \leqslant x[/tex]

So

[tex]x \geqslant - 5[/tex]

However x can not be -2. so we say

[-5,-2) U (-2,oo)

The range for this situation is {125, 150, ... 250}.

The range of a function includes all the possible output (y) values when the x value is substituted with a number.

The daily cost of hiring a lawn service = y

The number of hours mowing = x hours

Fixed cost per day = $100

Variable cost per hour = $25

Maximum hours of work per day = 6 hours

Minimum hour of work per day = 1 hour

y = 100 + 25x

y = 100 + 25(6)

y = 250

y = $250

For 5 hours, y = $225 (100 + 25(5)

For 4 hours, y = $200 (100 + 25(4)

For 3 hours, y = $175 (100 + 25(3)

For 2 hours, y = $150 (100 + 25(2)

The image distance is 33.3 cm and the magnification is 0.333  .

In the question ,

it is given that

since the lens is diverging

the focal length (f) = -50 cm

the distance between flower and diverging lens  (u) = -100

the formula to find the image distance is given by the equation

1/f = 1/v - 1/u

Substituting the values of f and u in the equation ,

we get

-(1/50) = 1/v - (-1/100)

1/v = -1/50 - 1/100

1/v = -3/100

v = -(100/3)

v = -33.33

formula for magnification = -(v/u)

Answer:

Each movie costs $3.75 while each video game costs $5.50.

Step-by-step explanation:

Let the cost of each movie and the cost of each video game be $x and $y respectively.

6x + 5y = 50 ------ equation (1)

2x + 3y = 24 ------ equation (2)

Subtract 3 times of equation (2) from equation (1):

(6x + 5y) - 3(2x + 3y) = 50 - 3(24)

    6x + 5y -  6x - 9y = 50 - 72

                           -4y = -22

                            4y = 22

                           ∴ y = 5.5

Substitute y = 5.5 into equation (2):

2x + 3(5.5) = 24

            2x = 7.5

           ∴ x = 3.75

Answer:

x = 4 and y = 3

Step-by-step explanation:

You are looking for the value of x and y when: 2x - 3y = -1 and y = x - 1

Because you are given y in terms of x (the second equation given), substitute that into the first equation for y:

2x - 3y = -1 when y = x - 1

2x - 3(x - 1) = -1

expand left side:

2x - 3x + 3 = -1

combine x terms on left side:

-x + 3 = -1

subtract 3 from both sides:

-x + 3 - 3 = -1  - 3

-x = -4

divide both sides by -1:

-x/-1 = -4/-1

x = 4

now use x = 4 in one of the original equations to solve for y. For simplicity sake, we will use the second equation but the answer can also be found by substituting x = 4 into the first equation.

y = x - 1 when x = 4

y = 4 - 1

y = 3

Answer:

x = 4; y = 3

Step-by-step explanation:

2x - 3y = -1

y = x - 1

Copy the first equation.

Subtract x from both sides of the second equation and multiply both sides by 3. Write it below the first equation. Then add the equations eliminating y. Solve for x.

     2x - 3y = -1

+   -3x + 3y = -3

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

      -x        = -4

x = 4

Now substitute 4 for x in the second original equation and solve for y.

y = x - 1

y = 4 - 1

y = 3

Answer: x = 4; y = 3
