Answer:
Step-by-step explanation:
hello :
here is two examples:
1) x²-9=0 means : x²-3² = (x-3)(x+3) = 0 .... use identity : a²-b² = (a-b(a+b)
use the Zero Product Property; x-3=0 or x+3=0 so : x=3 or x= +3
2) x²+4x = 0....using factoring : x(x+4)=0 means : x=0 or x+4=0
x=0 or x= - 4
Answer: Relationship between c and f is 7c - 3f = 0
Since Clare has to use 9 cups each of them having 1/3 part filled with flour for making of 4 cakes.
:
{-15(1.5) + {(-2.5)(1.25)}}
{-22.5 + (-3.125)}
{-22.5 - 3.125}
-25.625
Answer:
y-2=2(x-1)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(8-2)/(4-1)
m=6/3
m=2
y-y1=m(x-x1)
y-2=2(x-1)
