1 lemon costs 20p and 1 orange costs 45p so an orange costs 25p more
Answer:
I think it will be 54.125%
If you can graph in slope intercept, your new equations would be: y= -2x-1 and y= 2/3x-3.
Just graph those now since it should be easier.
Answer: Option C
Step-by-step explanation:
Given the quadratic equation , substitute :
In this case, to find the solutions of the given quadratic equation, you must factor out the variable "x". Then:
Therefore, you get that the solutions of this equation are the following:
Then, the answer is:
This matches with the option C.
