Divide 3 from both sides to get a=57/3 then a=19
Answer:
the last one
Step-by-step explanation:
plug in -2 for x and -3 for y
Answer
Find out the what is the value of x when y = 8 .
To prove
As given
The variables y and x have a proportional relationship.

y = kx
Where k is the constant of proportionality.
As y = 5 when x = 4
Put in the above
5 = 4k

Now find out the value of x , when y = 8


x= 6.5
Therefore when y = 8 than x = 6.4
The dimensions are Width of the rectangle = 7.2 cm
Length of the rectangle = 4x + 9.7
= 28.8 + 9.7
= 38.5 cm. thats all
Answer:
It’s domain
y>0
x>0
(so basically d)
