Answer:

i think it means pre image (plural pre images) (mathematics) For a given function, the set of all elements of the domain that are mapped into a given subset of the codomain; (formally) given a function ƒ : X → Y and a subset B ⊆ Y, the set ƒ−1(B) = {x ∈ X : ƒ(x) ∈ B}. The pre image of under the function is the set .

Answer:

I forgot what the letter was for this option but The Pre image is a geometric shape BEFORE a transformation occurs ( I think that's option B but u should read it to be sure)

Step-by-step explanation:

24 play volleyball

15 play soccer

Softball= 60-(24+15)=21

or

2/5 = 40%

100% -(40+25)= 35%

60x0.35=21

Answer:

[tex]x^2-15x+56[/tex]

Step-by-step explanation:

Use the FOIL distributive method: [tex]\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd[/tex]

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

Thus, [tex]\left(x-7\right)\left(x-8\right)=x\times x +x\left(-8\right)+\left(-7\right)x+\left(-7\right)\left(-8\right)[/tex]

Multiply them to get:

[tex]x^2-8x-7x+56[/tex]

[tex]x^2-15x+56[/tex]

Answer:You will be saving $3.10

Answer:

Step-by-step explanation:

3 T-Shirts price= 15.50

mean 1 T-Shirt price=5.16

3 T-Shirts shipping=12.60

mean 1 T-Shirt Shipping=4.2

If I get 4 then

4 T-Shirts price will be 5.16 x 4 = 20.65

4 T-Shirts shipping will be 4.2 x 4 = 16.8

Total cost will be = 37.45

So Company offers

4 T-Shirts in 14$ with free shiping

you will save 23.45

Answer: I HOPE IT HELPS OR WATCH  VIDOES  ABOUT IT

Step-by-step explanation:

Two unique points define a line.  Other geometric figures also may pass through those two points (you will learn those later).

There are several forms of the equation of a line:

     Standard form                           Ax + By = C

     Slope-intercept form                  y = mx + b

     Point-slope form                        y – y1 = m(x – x1)

     Two-point form              y – y1 = [ (y2 – y1)/(x2 – x1) ](x – x1)

O.K., you picked the two-point form, right?    

               The points are  P1:  (5,5) and P2: (7,-4)

    y - 5 = [ ((-4) - 5)/(7 - 5) ] (x - 5)          (put in x and y values of points)

    y - 5 = [  -9 / 2 ](x - 5)                         (simplify)

    y - 5  =  -9/2x  + 45/2                           (distribute -9/2)

     y =  f(x) = -9/2x + 55/2                   (add 5 to both sided)

Check (very important):

  Is (5,5) on the line?      5 = (-9/2)(5) +  55/2  ?

                                         5 =  -45/2   +  55/2  ?

                                          5 =  10/2         yes.

  Is (7,-4) on the line?     -4 = (-9/2)(7) + 55/2       ?

                                          -4  =  -63/2   + 55/2   ?

                                          -4  =   -8/2   ?       yes.

Answer:

525 students

Step-by-step explanation:

84/4 is 21. The ratio is 1 teacher to every 21 students. There are 25 teachers in the entire school. If you multiply that by 21, there are 525 students in the entire school.

Answer:

2491.50$ oooooooooooooooooooooooo

The amount withheld from his biweekly pay for state income tax is $2491.5.

The percentage is defined as a ratio expressed as a fraction of 100.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

We have been given that the physical therapist earns $49,830 a year and is single with no dependents.

To determine the amount withheld from his biweekly pay for state income tax.

Since the state income tax rate is 5% of taxable income.

So the amount withheld from his biweekly pay for state income tax as:

⇒ 5 % of 49,830

⇒ (5/100)49,830

⇒ (0.05)49,830

⇒ 2491.50

Therefore, the amount withheld from his biweekly pay for state income tax is $2491.5.

Answer:

158

Step-by-step explanation:

If I is the midpoint of JH, JI= IH

JH= JI +IH

JH= JI +JI (subst. IH= JI)

JH= 2(JI)

Since JI= 79,

JH= 2(79)

JH= 158

Answer:

D) -1

Step-by-step explanation:

6x-2≥4x-6

6x-4x≥-6+2

2x≥-4

x≥-4÷2

x≥-2

Only -1 is greater than -2 in the list.

Answer:

x = - 1

Step-by-step explanation:

Given

2(3x - 1) ≥ 4x - 6 ← distribute parenthesis on left side

6x - 2 ≥ 4x - 6 ( subtract 4x from both sides )

2x - 2 ≥ - 6 ( add 2 to both sides )

2x ≥ - 4 ( divide both sides by 2 )

x ≥ - 2

The only value in the list greater than - 2 is - 1

x = - 1 is in the solution set

Answer:

r = -3

Step-by-step explanation:

- 60= - 24 + 12r

Add 24 to each side

- 60+24= - 24+24 + 12r

-36 = 12r

Divide each side by 12

-36/12 = 12r/12

-3 =r

Step-by-step explanation:

Answer:

Option (A)

Step-by-step explanation:

Heights above the sea level are denoted with positive notations and depths below the sea level with negative.

Height of the highest peak of the mountain = +2228 meters

Lowest point of the lake = -15 meters

Difference between these elevations = 2228 - (-15)

                                                              = 2243 meters

Therefore, Option (A) will be the correct option.
