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 .

Step-by-step explanation:

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)

Answer:

Bro this some alien hyroglyphics

Step-by-step explanation:

Answer:

m = - 27

Step-by-step explanation:

Given

3(m - 5) + 11 = - 85 ← distribute and simplify left side

3m - 15 + 11 = - 85

3m - 4 = - 85 ( add 4 to both sides )

3m = - 81 ( divide both sides by 3 )

m = - 27

*Instead of rewriting PF to QF +43 in part (a), you could also leave PF as it is and rewrite QF as PF -43 after the line I labelled as equation 2. The working would be about the same, just that you would not need to add 43 again in picture 3 because we would be working with PF. (PF would be factorised out instead)

The answer is 23 my Dear random friend!

Step-by-step explanation:

Answer:

See Below

Step-by-step explanation:

14 + x = -9

To isolate x, subtract 14 from both sides

14 + x =  -9

-14         -14

x = -(14+9)

x = -23

The situation of balloon B

Step-by-step explanation:

Balloon A is released 5 feet above the ground and our ground level be 0 feet. Let k be the rate at which it rises and t the time it takes to rise. Its height y, above the ground after time x is y = kt + 5

For Balloon B since it is released at ground level at which ground level is taken as 0 feet, let t be the time it takes to rise above the ground and k the rate at which it rises above the ground. Its height y above the ground after tie x is y = kt

Since the expression for Balloon B is y = kt and the expression for Balloon A is y = kt + 5, only the situation of Balloon B can be expressed in the form y = kx.

This is because the rate of rise of Balloon B follows a direct proportionality while the rate of rise of Balloon follow a joint proportionality since it starts from a point other than ground level.

Answer: 16 points for the first half game

Step-by-step explanation:

1st half = ?

2nd half= p

Total = 18

The expressions to get the score of the 1st game is 18 -p

If she scored 2points in the second half game that means p=2

To get the 1st half of the game you should do 18-2=16

Reflection

Step-by-step explanation:

Answer:

The slope is 6. For the first line you could do y=6x+7, and the line parallel to that could be y= 6x+3

Step-by-step explanation:

For it to be parallel the slopes have to be the same and the y intercepts (b) have to be different. And I found the slope by doing y-y/x-x

(x - 3)/2= 1

x - 3 = 2

x = 5

(y - 8)/2 = -2

y - 8 = -4

y = 4

(5, 4) coordinates for B

The coordinates of B are (5, 4) if the midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8),

It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).

[tex]\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|[/tex]

It is given that:

The midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8).

Let the coordinate of B is (x, y)

From the midpoint theorem:

(x - 3)/2= 1

x - 3 = 2

x = 5

For y coordinate:

(y - 8)/2 = -2

y - 8 = -4

y = 4

(5, 4) coordinates for B

Thus, the coordinates of B are (5, 4) if the midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8),

The complement = x

The angle we are finding = 3x + 26

Complementary angles are angles that add up to 90 degrees.

90 = x + 3x + 26

Combine like terms

90 = 4x + 26

Subtract 26 from both sides

64 = 4x

Divide both sides by 4

16 = x

The angle we are trying to find = 3(16) + 26 = 48 + 26 = 74 degrees

Answer: 47 ft

Step-by-step explanation:

Answer:

x = -6

Step-by-step explanation:

Step 1: Write out equation

5x + (-2) = 6x + 4

Step 2: Simplify

5x - 2 = 6x + 4

Step 3: Subtract 5x on both sides

-2 = x + 4

Step 4: Subtract 4 on both sides

-6 = x

Step 5: Rewrite

x = -6

Answer:

x = -6

Step-by-step explanation:

[tex]5x+(-2)=6x+4[/tex]

Open the parenthesis

[tex]+(-2) =-2\\\\5x -2 =6x+4[/tex]

Collect like terms and simplify

[tex]5x-6x =4+2\\-x =6[/tex]

Multiply through by -1

[tex]-1(-x)=-1(6)\\\\x = -6[/tex]
