Answer: Y =-5.6
Step-by-step explanation:
Y= K/X if y =7, x= -4 then substituting in the equation 7=K/-4
Then K= -28
Find y if x is 5.substituting 5 in the equation is Y=-28÷5 = -5.6
Answer:
15/4

f(1) = -12
Answer:
x=-2, y=-3
Step-by-step explanation:
we can rearrange the questions to make it easier
y=3x+3
2y=-3x-12
if you add the two equations, you get
3y=0x-9
so y=-9/3 = -3
plug y into one of the equations
-3=3x+3
-6=3x
x=-2
and then check your work by plugging into the other equation:
2*-3=-3(-2)-12
-6=6-12
-6=-6
16 cubic inches or 13 oz.
