Answer:

Step-by-step explanation:
From the question we are told that
Dimension of drawing
20 centimetres by 10 centimetres
Scale of drawing
1 cm:250 cm
Generally the the Main dimension of the pool is mathematically given as

Therefore Area Aof main pool is mathematically given as


You have to start by using the distributive property on the left side.
3(2x-7)=5x+4
6x-21=5x+4 Then remove and combine alike terms.
+21 +21
6x=5x+25
-5x -5x
x=25
By definition a function can have only one value of y for any given value of x.
Since B. contains both (-1,2) and (-1,0), y has two values for the same value of x and thus B. cannot be a function...
Answer:
y=32x shows a proportional relationship.
Step-by-step explanation:
We need to find an equation that shows the proportional relationship.
If x and y are proportional to each other, it will look like,
y = mx
Where
m is constant of proportionality
Out of 4 option, option (4) is y=32x, it shows the proportional relationship where the value of m is equal to 32.
