Step-by-step explanation:
x²+x-12=0
by factorization
x²-3x+4x-12=0
taking common
x(x-3)+4(x-3)
(x+4)(x-3)
x= -4. x=3
I think they are looking for a +, maybe
Answer:
10 cups of milk
Step-by-step explanation:
Make a proportion, where x is the number of cups of milk for 165 cookies:
=
Cross multiply and solve for x:
11x = 110
x = 10
So, 10 cups of milk are needed to make 165 cookies
True, y=7 means its just a horizontal line running straight through the 7 on the vertical/y-axis.
So domain is the numbers you can use to put in the function
range is the numbers you get from putting the numbers from the domain in the function
so
domain can only have positive numbers because you cannot have a negative trajectory so the domain is all positive numbers
and the range is positive until x=25.5
