Using the calculator to solve the quadratic equation given above, the roots that can be obtained is -1/2 and -5/2. Hence the answer should be C. Another way to solve this is to get the factors such that the sum is equal to the second term and the third term is the product of the factors

For the table, y = 9x.

 so the price of a short cake is $9


For the graph, y = 4x
so the price of a sweet bread is $4

9-4 = 5

 the short cake is $5 more than the sweet bread

What is the value of x?<br> 4x − 6 = 18
tensa zangetsu [6.8K]
You need to get rid of -6 by adding 6, you also need to add 6 to 18.

4x = 24

Now you need to get rid of the 4 attached to the variable, you do this by dividing 4 since it is multiplying, also dividing 4 and 24

x = 6

So the value of x is 6

Hope this helps! :)

If 60 marks is 40%, how much is full marks (Show your working out)?
Vitek1552 [10]
' 40% ' means 0.4 .

You said that                           60          = 0.4 x Full

Divide each side by 0.4 :       60 / 0.4  =   1  x Full

                                                       Full  =  150 .
