D is the correct answer

Answer:

Step-by-step explanation:

let y = f(x), that is

y = $\frac{2x-3}{5}$

Rearrange making x the subject

Multiply both sides by 5

5y = 2x - 3 ( add 3 to both sides )

5y + 3 = 2x (divide both sides by 2 ) , then

x = $\frac{5y+3}{2}$

Change y back into term of x, hence

$f^{-1}$ (x) = $\frac{5x+3}{2}$ → D

The answer is positive 1/5. Here is a tip, when reading a graph read from left to right. If it is going up to the right it is positive. If it goes down going to the right it is negative. Also think rise/run. Count how many times it goes up(or down) then count how long the line goes.

Answer:

y = 0.3X + 18.3

Step-by-step explanation:

Given that data :

x = year ;

y = trunk diameter, in inches

Year ________trunk diameter

1 __ 18.6

3 __ 19.2

5 __ 19.8

7 __ 20.4

9 ___21.0

11 __ 21.6

13 __ 22.2

Using the linear regression calculator :

The linear equation obtained is :

y = 0.3X + 18.3

Where ;

Slope = 0.3 ; intercept, c = 18.3

Vilka [71]

Answer:

B.)536 $cm^{3}$

Step-by-step explanation:

Find the volume of all the fish tanks.

Green fish tank...

4 x 9 x 6 = 216

Brownish fish tank...

4 x 4 x 8 = 128

Orange Fish tank...

6 x 4 x 8 = 192

Since we are COMBINING the fish tanks, we add the volumes.

216 + 128 + 192 = 536

536 $cm^{3}$

Hope this helped! Please mark as brainlies! Thanks!
