The answer is x= 4 and y= -3
6x-4y=36 -- (1)
2x-8y=32- (2)
from (1)
-4y= 36-6x
y= -9+3/2x
(3) into (2)
2x-8(-9+3/2x)=32
2x+72-12x=32
72-10x=32
-10x= -40
x= 4
sub x=4 into y= -9+3/2x
y= -9+3/2(4)
y= -3
Answer:
£200/£300
Step-by-step explanation:
#6
Yes
Direct variation because Time increases cupcakes increases and vice versa
#B
Constant of proportionality represents the amount of time required per cupcakes
#7
Yes we can find it
We have to check the x and y values of the ordered pairs (x,y)
If y is decreasing with respect to increase in x then it's inverse variation
then the angle formed would be equal to 180 degree
