If x is the amount of time Gillian takes,
1/10 - 1/x = 1/25
Therefore, the answer is A
B. 84
The scale factor is 1/12 which means to get back to the actual height, you would multiply 7x12
Answer:

Step-by-step explanation:
Write the equations in the form y = mx + b
If the equation contains exponents then it is non-linear, if not then it is linear.
2xy = 3
This graph forms a curve so it is non-linear
y = 1x³ + 5
This equation is non-linear because it contains an exponent
y = x/3
y = 1/3x + 0
This equation is linear ( no exponent(s) )
2y = 1/2x
y = 1/4x + 0
This equation is linear ( no exponent(s) )
