Answer:
k = 3
Step-by-step explanation:
Expand the left side and compare the coefficients of like terms on both sides.
(2x - 1)(kx + 1) ← expand using FOIL
= 2kx² + 2x - kx - 1
Compare the coefficients of the x² term on both sides
2k = 6 ( divide both sides by 2 )
k = 3

Answer:
Speed = 0.2 miles per minute.
Step-by-step explanation:
Given : Jamaal ran 6 miles in 30 minutes.
To find : Which expression shows how to correctly determine his speed in miles per minute.
Solution : We have given
Distance = 6 miles.
Times= 30 minute .
Speed =
.
Speed =
.
Speed = 0.2 miles per minute.
Therefore, Speed = 0.2 miles per minute.
For this case we must complete squares:

We add the square of half the coefficient of the term "x",
on both sides of the equation:

According to the perfect square trinomial we have:

Rewriting the expression we have:

Answer:
Real numbers consist of zero (0), the positive and negative integers (-3, -1, 2, 4), and all the fractional and decimal values in between (0.4, 3.1415927, 1/2). Real numbers are divided into rational and irrational numbers.
