3 0

set f(x) equal to y

y = 5x + 4

swap x and y

x = 5y + 4

make y the subject

x - 4 = 5y

y =  \frac{x - 4}{5}

replace y with f^-1(x)

f(x) =  \frac{x - 4}{5}

Find the x and y intercepts of the equation 8x+y=-9
Juliette [100K]

Answer:

see explanation

Step-by-step explanation:

To find the intercepts, that is where the graph crosses the x and y axes.

• Let x = 0, in the equation for y-intercept

• Let y = 0, in the equation for x-intercept

x = 0 : 0 + y = - 9 ⇒ y = - 9 ⇒ (0, - 9 ) ← y- intercept

y = 0 : 8x + 0 = - 9 ⇒ x = - \frac{9}{8} ⇒ ( - \frac{9}{8}, 0) ← x- intercept

A driveway has an area of 96 square feet. The width of the driveway is 8 feet.
Mrrafil [7]

Answer:

12 feet

Step-by-step explanation:

A driveway is rectangular in shape.

Therefore we can calculate the area using the formula;

A = L \times W

From the question;

The area,A=96 feet square

The width, W=8 feet

We substitute this values into the formula to find the length, L.

This implies that

96 =L \times 8

Dividing through by 8.

\implies \frac{96}{8}= \frac{L \times 8}{8}

\implies L = 12

Hence,the length of the driveway is 12 feet.
