Answer:
(-19 , -7)
Step-by-step explanation:
y - x = 12
y + x = -25 we sum them to get
2y = -14 , y = -7
then we put -7 instead of y in any of the equations:
-7 - x = 12
-x = 19
x = -19,
finally (x , y) is (-19 , -7)
Answer:
y = 6
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 3 when x = 9, then
k =
=
=
, thus
y =
x ← equation of variation
When x = 18, then
y =
× 18 =
= 6
Answer:
174879 units
Step-by-step explanation:
Given that The Elmina Wilson Company produces spaghetti sauce.
Fixed costs =1,329,050 $
Selling price per 64 oz=
Variable cost per can = 
Contribution = S-V=Selling price - var cost = 7.60 $
Break even poin in no of units = Fixed cost/Contribution per unit
=
-4 and -5
because to get 16 to 12 you have to subtract 4 but it wants you to add so you put a negative sign infront of it.
and a negative multiply by a negative equals a positive so -3×-5=15
