Find the inverse of y=5x+3

Mathematics
1 answer:
seraphim [82]3 years ago
5 0

Answer:

f^{-1}(x) = \frac{x-3}{5}

Step-by-step explanation:

Rearrange the equation making x the subject

y = 5x + 3 ( subtract 3 from both sides )

y - 3 = 5x ( divide both sides by 5 )

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

Change y to x then

f^{-1}(x) = \frac{x-3}{5}

Find the area of the figure. Round to the nearest tenth
Reika [66]

Answer:

Find the area of each triangle and then add it up. As you are aware, to find the area of a triangle the equation is B times Height divided by 2.  And to make it easier do the top left triangle and the top right triangle, add them together and then divide that by 2.

Step-by-step explanation:

3 time 5 equals 15 divided by 2 equals 7.5

5 times 8 equals 40 divided by 2 equals 20

7.5 plus 20 equals 27.5

27.5 times 2 equals 55

therefor your answer should be 55m
