Answer:
Option (B).
Step-by-step explanation:
Percentage change between two numbers a and b can be calculated by the formula,
% change = 
Where, (b - a) = Change in values
a = Initial value
If a = 16 and b = 20
Percentage change between 16 and 20 will be,
= 
= 
= 25%
If a = 20 and b = 16,
Percentage change = 
= 20%
Therefore, %change between 16 and 24 may be 16% or 20%.
Option (A),
= 25%
Option (B),
= 1.25 - 1 × 100
= 1.25 - 100
= -98.75%
Option (C),
= 25%
Option (D),
= 20%
Therefore, we can not use the calculation used in Option (B).
I’m in high school I’m sorry about that
12x+1=-7
-1 -1
12x=-6
/12 /12
x=-1/2 or x=-0.5
Answer:
13x - 12 =
Step-by-step explanation:
17x + (-4x) = 13x
(-5) + (-7) = -12
Standard form is y = mx + c where m is the gradient and c is the y-intercept.
So it would be y = 1/4x - 3
