What is the inverse of f(x)=2x-4​

Mathematics
1 answer:
Phantasy [73]3 years ago
4 0

Step-by-step explanation:

Hey there!

The given function is; f(x) = 2x-4.

<u>To find: f'(X) </u>

Let f(X) be y, then;

y = 2x - 4

Interchanging"X" and "y" we get;

x = 2y - 4

or, X+4 = 2y

or, y = (X+4)/ 2

Therefore, f'(X) = (X+4)/2.

<u>Hope</u><u> it</u><u> helps</u><u>!</u>

If L is parallel to M, find the values of x, y, and all 3 angles.
lesya [120]

Answer:

8x - 14 = 5x + 34 (alternate exterior angles)

8x - 5x = 34 + 14

3x = 48

x = 48/3

x = 16

5y + 16 + 8x - 14 = 180 (linear pair)

5y + 16 + 8(16) - 14 = 180

5y + 16 + 128 - 14 = 180

5y + 130 = 180

5y = 180 - 130

5y = 50

y = 50/5

y = 10

∠ (8x - 14) = 114   [(8 × 16 -14)=114]

∠ (5x + 34) = 114  [(5 × 16 +34)=114]

∠ (5y + 16) = 66   [(5 × 10 +16)=66]

hope this helps you!

Leah loves chicken wings and is comparing the deals at three different restaurants. Buffalo Bills has 888 wings for \$7$7dollar
ella [17]

Cost of chicken wings at Buffalo Bills = 8 wings for $7

Cost of 1 wing at Buffalo Bills = \frac{7}{8} =0.875

Cost of chicken wings at Buffalo Mild Wings = 12 wings for $10

Cost of 1 wing at Buffalo Mild Wings = \frac{10}{12}= 0.833

Cost of chicken wings at Wingers = 20 wings at $17

Cost of 1 wing at Wingers = \frac{17}{20}= 0.850

Hence, comparing all the three costs per wing, we can see that Buffalo Mild Wings is serving chicken wings at lowest price of $0.833 per wing.

plsss helppp need it fastt .. what is the volume of this figure answer your answer in the box . 4ft 3ft 8ft 2ft 6ft
PolarNik [594]

Answer:

e

Step-by-step explanation:

The cube on the top, the one with the width of 4 is Cube 1.

The other one is Cube 2.

The length of the cube is 4, the width 2, and the height 5.

We know the length is 4 because we can look at the side, where both measurements 6 ft and 3 ft can be found.

We know that the height is 5 because for Cube 2, the height is 3. The total height is 8, so we subtract 3 from 8. We get our difference of 5.

V = l x w x h

V = (4)(2)(5)

V = (8)(5)

V = 40.

Cube 2 has a length is 6, the width 2, and the height 3.

V = l x w x h

V = (6)(2)(3)

V = (12)(3)

V = 36

We add the volumes of both cubes.

40 + 36 = 76

probs not right but hope it helped :)
