Answer:
B
Step-by-step explanation:
A is correct because 
was added on both sides, which is supported by the Additive Property of Equality
C is correct because the Quotient Property of Logarithms states that 
so 
is correct
D is correct because using the fact that 
it is easy to figure out that x=12
For B, there is no property supporting that statement.
1 m = 5 cm
6 m = 6 * 5 = 30 cm
20 m = 20 * 5 = 100 cm
dimensions are : 30 cm by 100 cm
Hello!
So to find the y-coordinate we need an equation for the line. The equation we can use is
y = mx + b
In this we already know m(the slope which is 3) and we can find b by plugging in the points that are given.
10 = 3(0) + b
10 = 0 + b
10 = b
So now that we've found b, we can use this in our equation
y = 4x + b
So now we can plug in the x-coordinate that we know (2) and find the y - coordinate.
y = 4(2) + 10
y = 8 + 10
y = 18
18 is your y-coordinate
