See the comment above.
Interchange the x and y in the original equation. call f(x) = y just for ease of understanding.
y = 3x + 5
Inverse
x = 3y + 5 Now solve for y.
(x - 5) = 3y Divide by 3
(x - 5)/3 = y

Remove the brackets.
x /3 - 5/3 = y

The answer is D <<<<< answer.

Ivan and Tanya share £150 in the ratio 4: 1<br>Work out how much more Ivan gets compared to Tanya.

Anastasy [175]

Answer:

Ivan got £90 more than Tanya.

Step-by-step explanation:

Ivan and Tanya share the amount £150 in the ratio of 4 : 1

Amount received by Ivan = $150\times \frac{4}{(4+1)}$

= $150\times \frac{4}{5}$

= £120

Similarly, amount received by Tanya = $150\times \frac{1}{(4+1)}$

= £30

Difference in their amounts = 120 - 30

= £90

Therefore, Ivan got £90 more than Tanya.

Bryan sells cars. He makes a salary of $500 a week, plus $150 for every car he sells. This week, he wants to make at least $2000

Kobotan [32]

If Bryan wants to make $2000 dollars then he needs to solve this equation:

2000=500+150x
-500 -500

1500=150x divide by 150 on both sides

x=10

10 cars

James earned a total of $900 last week.This total was $10 less than five times the amount he earned last week. How much money di

Hoochie [10]

Hello!

Let's change it to an equation.

$5x - 10 = 900$

Switch the equation around

$900 = 5x - 10$

First add 10 from 900

$900 + 10 = 910$

$5x = 910$

Divide both sides by 5

$\frac{5x}{5} = \frac{910}{5}$

$\framebox{x = 182}$
