A "system" of equations is a set or collection of equations that you deal with all together at once. Linear equations (ones that graph as straight lines) are simpler than non-linear equations, and the simplest linear system is one with two equations and two variables.
Answer: The first one (A) f(x)= x (x-a)(x-b)²
Step-by-step explanation: Trust me, it’s right
Answer:
w = 13
Step-by-step explanation:
Using the method of cross- multiplying
•
=
⇒ ad = bc, thus
42(w + 11) = 28(w + 23) ← distribute parenthesis on both sides
42w + 462 = 28w + 644 ( subtract 28w from both sides )
14w + 462 = 644 ( subtract 462 from both sides )
14w = 182 ( divide both sides by 14 )
w = 13
