Eliminate the parameter t:t=y/2
x=y^2/2+3
First, find the base rate of both of the numerals, to do this simply divide the price by the number of units.
12.95 divided by 3 is 4.32 ( rounded to nearest cent )
21.45 divided by 5 is 4.29 ( rounded to nearest cent )
So, if you want the better deal ( which is what I've interpreted ), then 5 pounds of nuts is the better deal <u>BY</u> 3 cents.
Hope this helps, if not, comment below please!!!!
Answer:
d^2 +2d-8=0
first pick two numbers which add up to make +2 and by multiplying those two numbers they should be able to create -8.
so for example 4 and 2
4-2=2
4 x -2= -8
so now factorise:
d^2 +2d-8=0
d^2+4d-2d -8=0
d(d+4)-2(d+4)=0
d+4=0 d-2=0
d=-4 d=2
