Answer:

Option B is the correct choice.

Step-by-step explanation:

The graph is attached below.

We have to find the x intercept meaning the value of the point onx-axis when y=0

So we will put the value of zero (0) instead of y in our given equation.

So here we have solved it algebraically.

y=\frac{3}{4}x-3

Putting y=0

0=\frac{3}{4}x-3

0=\frac{3x-12}{4}

Multiplying 4 both sides.

0=3x-12

Adding 12both sides.

12=3x

Dividing with 3 both sides.

x=\frac{12}{3}=4

So the x-intercept of the given equation is 4 which can be written as (4,0) in terms of coordinates.

Option B (4,0) is the correct choice.

The price of a flight was increased by 3% to £650. What was the price before the increase?
liubo4ka [24]

Answer:

£ 631

Step-by-step explanation:

Hi this is a simple mathematics issue.

First, let's imagine what is 3%. '3 percents' means 3/100. If your family have 100 apples and you have 3 apples, that means you have 3% of your family apples.

Now, get back to this problem. We need to find the price before increase. Let's say the price was £ X. Now we will find the X number.

It's said that the price was increased by 3%. That means they took 3% of X and added that amount to X to have the new price : £ 650. That means we have this equation :

650 = X + 3%×X

Let's make it easier to look :

650 = X + 3/100 ×X

650 = X×( 1+ 3/100)

= X × 103/100

So we can see 650 is equaled to X multipled by 103/100.

To find the correct answer, simply divide 650 by 103/100.

*A hint: When you divide a number by a fraction, you can simply put the number multiplied by the "flipped" fraction .

Hope you learn with Joy and High Grades !!!
