F(x)=4x+7. Find the inverse of f(x).

Mathematics
1 answer:
liraira [26]3 years ago

Answer:

Step-by-step explanation:

f(x) = y = 4x + 7

Solve for "x"

4x + 7 = y ⇒ x = \frac{1}{4} y - \frac{7}{4}

Exchange the places "x" and "y"

f^{-1}(x) = \frac{1}{4} x - \frac{7}{4}  

or f^{-1} (x) = \frac{x-7}{4}

Answer:

Option B is the correct choice.

Step-by-step explanation:

The graph is attached below.

We have to find the x intercept meaning the value of the point onx-axis when y=0

So we will put the value of zero (0) instead of y in our given equation.

So here we have solved it algebraically.

y=\frac{3}{4}x-3

Putting y=0

0=\frac{3}{4}x-3

0=\frac{3x-12}{4}

Multiplying 4 both sides.

0=3x-12

Adding 12both sides.

12=3x

Dividing with 3 both sides.

x=\frac{12}{3}=4

So the x-intercept of the given equation is 4 which can be written as (4,0) in terms of coordinates.

Option B (4,0) is the correct choice.

Can u guys pls help me on this question and pls explain how u got the answer
DaniilM [7]

Answer:

192 mm

Step-by-step explanation:

The area of a triangle is 1/2 bh and the base is 8 and the height is 8. 8*8= 64 divided by two is 32. There are four of these sides, so 4* 32 is 128. Then you also have to account for the square bottom which has dimensions of a width of 8 and a height of 8 making the bottom 64. When you add 128 and 64 together you get 192.

Hope this helped

If 1m is 100cm, then 250cm equivalent of 2.5m<br> if 1kg is 1.00g then 3kg is 2.500g
Viefleur [7K]

Answer:

I Kg = 1000 g

3 Kg = 3000 Kg

Step-by-step explanation:

Kg - Hg - Dag - g

1 Kg - 10 Hg - 100 Dag - 1000 g

So, 1 Kg = 1000 g

3 Kg = 3(1000)g = 3000 g

In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
