Margaret [11]3 years ago

We write f(x) in terms of y I.e y=7x-1/2.

Fractions are sometimes ambiguous, we eliminate the fraction by multiplaying the entire function by 2.so as to get 2y=14x-1.

Make x the subject, x=2y+1/14,

Thus the inverse f(x)=2x+1/14

0. Juan has been saving for a new bike for two months. So far, he has saved
antiseptic1488 [7]

<u>Given</u>:

Juan has been saving for a new bike for two months. So far, he has saved $150 for the bike.

The money that he has saved so far is 30% of the cost of the bike.

We need to determine the total cost of the bike.

<u>Total cost of the bike:</u>

Let x denote the total cost of the bike.

The total cost of the bike is given by

30\% \ of \ x=150

The value of 30% can be written as \frac{30}{100}

Thus, we get;

\frac{30}{100} \times x=150

Multiplying both sides by \frac{100}{30}, we have;

x=150 \times \frac{100}{30}

Simplifying, we have;

x=\frac{15000}{30}

x=500

Thus, the value of x is 500.

Hence, the total cost of the bike is $500.
