A^2-8a-48=0
factor
(a+4)(a-12)=0
set each equal to 0
a+4=0 a-12=0
a=-4,12
Step-by-step explanation:
y=kx
say that y is the original prince and x is the sale price
15=k(10)
15/10=k
3/2=k
you can check with the next problem to check if it is the same
25=k(20)
25/20=k
5/4=k
so you take 5/4-3/2=-1/4 so the constant is -1/4
Hope that helps :)
3 & 5 are the coefficient ones because they are multiplying a variable
To get the answer the first thing you wanna do is plug in the numbers so that would be (8)(3)(12)/(2)(12)(4)= than you would multiply the numbers and you should get 288 divided by 96 and the answer is 3
