Anything multiplied by 1 is itself. So a rational number multiplied by 1 = the rational number.
Y=mx+b
m=slope
b=yint
slope=5/6
ying=-3
equation is y=5/6x-3
First, you must know the meaning of the words used in the problem. For example, what is the definition of a constant term?
constant term: a number of a fixed value that is unaccompanied by a variable.
For example:
Y= 2x +7 (in this example "7" is the constant term because its value cannot be changed by any variable)
I would argue that, because every term is followed by an "x" in this equation, there is no constant term unless you were allowed to factor out an "x" from every term in the equation. However, then the equation would no longer be in standard form.
Does this make sense?
Answer:
The Younger sister is 9
Step-by-step explanation:
x = age of older sister
x - 3 = age of younger sister
4/3 = x/(x - 3)
Solve for x.
4(x - 3) = 3x
4x - 12 = 3x
x = 12
The older is 12, the younger is 12 - 3 = 9
