Answer:

Step-by-step explanation:

f(x) = 3x + 1

f^-1 = x-1/3 , it is known as inverse function.

f(3)= 3*3 +1

=9+1

=10

To find inverse,

x=3x + 1

y=3x+1

Exchanging the position or x and y

x=3y+1

x-1=3y

.•. y=x-1/3

Select the correct answer.<br> Find the slope and the y-intercept of the equation 4x + 5y = -9.

Snowcat [4.5K]

Answer:

The answer to your question is letter C

Step-by-step explanation:

To find the slope and the y-intercept solve the equation of the line for y.

4x + 5y = -9

- Substract -4x in both sides

4x - 4x + 5y = -4x - 9

- Simplify

5y = -4x - 9

- Divide by 5 both sides

5y/5 = -4/5x - 9/5

- Simplify

y = -4/5x - 9/5

- Find the slope

m = -4/5

- Find the y-intercept

b = -9/5

Lisa's penny bank is 1/10 full. After she adds 440 pennies, it is 3/5 full. How many pennies can Lisa's bank hold?

aksik [14]

Answer:

Step-by-step explanation:

After the 440 pennies are added, the bank is 3/5 full. It started out 1/10 full, so

3/5 - 1/10 is the amount of space in the bank that the 440 pennies took up, or

1/2. Use proportions to solve this, with number of pennies on the top and the fraction of the bank that is filled on the bottom:

$\frac{440}{\frac{1}{2} }=\frac{x}{1}$

where x is the number of pennies (our unknown) that it will take to fill the bank (1). Cross multiply to get

$\frac{1}{2}x=440$

so x = 880

If the current price of bread dropped by 44 cents, 9 loaves of bread would cost as much as 7 do now. What is the current price o

Ann [662]

198 cents. Let current price of bread be x cents. 9(x-44) = 7x, 9x - 396= 7x, 2x=396, or x = 198.
