Step-by-step explanation:
commision = 7% of $9000
commision = 7/100 * $9000
commision = $630
Answer:
x2 - 4x - 21
Step-by-step explanation:
Area = (x -7 )(x +3)
= x*x - 7*x + x*3 - 7*3
=x2 - 4x - 21
Step-by-step explanation:
You can set up a proportion.
Let x be the number of pencils needed.
Solve for x.
x = 9444.44 pencils (round it up to 9445 pencils if you need a whole number)
Rewrite the given quadratic equation in standard form: Kx 2 + 2x - 1 = 0
Discriminant = 4 - 4(K)(-1) = 4 + 4K
For the equation to have two real solutions, the discriminant has to be positive. Hence we need to solve the inequality 4 + 4K > 0.
The solution set to the above inequality is given by: K > -1 for which the given equation has two real solutions.
