To solve, we can use an equation finding the average of the siblings'ages.
Answer:
x=25 or x=0
Step-by-step explanation:
4x(x−25)=0
Step 1: Simplify both sides of the equation.
4x2−100x=0
For this equation: a=4, b=-100, c=0
4x2+−100x+0=0
Step 2: Use quadratic formula with a=4, b=-100, c=0.
x=−b±√b2−4ac over 2a
x=−(−100)±√(−100)2−4(4)(0) over 2(4)
x=100±√10000 over 8
x=25 or x=0
For your question the answer is C.
Hope this helps:)
You used to say "y = 2x + 3; solve<span> for y when x = –1". Now you say "f(x) = 2x + 3; find f(–1)" (pronounced as "f-of-x is 2x plus three; find f-of-negative-one"). You do exactly the same thing in either case: you plug in –1 for x, multiply by 2, and then add the 3, simplifying to get a final value of +1.

Answer:
yes
Step-by-step explanation:
A rational number is in the form p/q where p and q are both integers and the denominator q is not equal to zero. This means that the set of all real numbers are rational numbers.
Since q can be any integer apart from zero, it means that all integers are rational numbers i.e for q = 1.
Hence 2 which can be written as fraction as 2/1 is a rational number since the denominator (q = 1) is a non zero number
