Answer: Choice D (aka 4th option)

C ' (-8, 1)

D ' (-6, 5)

E ' (-2, 4)

===========================================================

Explanation:

The x axis reflection rule is (x,y) \to (x,-y)

x stays the same while y flips in sign (positive to negative, or vice versa).

  • A point like C(-8, -1) will reflect to C ' (-8, 1)
  • The point D(-6, -5) reflects to D ' (-6, 5)
  • Lastly, the point E(-2, -4) reflects to E ' (-2, 4)

All of this points to Choice D as the final answer.

Answer:

last option is correct

Step-by-step explanation:

use formula of reflection over x axis .

The coordinates of C , D , E are (-8 , -1) , (-6 , -5) , (-2 , -4) respectively.

formula :

(x , y) = (x  -y)

C(-8 , -1) = C'(-8 , 1)

D(-6 , -5) = D'(-6 , 5)

E(-2 , -4) = E'(-2 , 4)

How do you find inverses
MrMuchimi

How To Find Inverses:

1. First, replace f(x) with y . ...

2. Replace every x with a y and replace every y with an x .

3. Solve the equation from Step 2 for y . ...

4. Replace y with f−1(x) f − 1 ( x ) . ...

5. Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.

A candy store owner wants to mix some candy costing $1.25 a pound
maria [59]

The candy store owner should use 37.5 pounds of the candy costing $1.25 a pound.

Given:

  • Candy costing $1.25 a pound is to be mixed with candy costing $1.45 a pound
  • The resulting mixture should be 50 pounds of candy
  • The resulting mixture should cost $1.30 a pound

To find: The amount of candy costing $1.25 a pound that should be mixed

Let us assume that the resulting mixture should be made by mixing 'x' pounds of candy costing $1.25 a pound.

Since the total weight of the resulting mixture should be 50 pounds, 'x' pounds of candy costing $1.25 a pound should be mixed with '50-x' pounds of candy costing $1.45 a pound.

Then, the resulting mixture contains 'x' pounds of candy costing $1.25 a pound and '50-x' pounds of candy costing $1.45 a pound.

Accordingly, the total cost of the resulting mixture is 1.25x+1.45(50-x)

However, the resulting mixture should be 50 pounds and should cost $1.30 a pound. Accordingly, the total cost of the resulting mixture is 1.30 \times 50

Equating the total cost of the resulting mixture obtained in two ways, we get,

1.25x+1.45(50-x)=1.30 \times 50

1.25x+72.5-1.45x=65

0.2x=7.5

x=\frac{7.5}{0.2}

x=37.5

This implies that the resulting mixture should be made by mixing 37.5 pounds of candy costing $1.25 a pound.
