Find the possible values of the constant k if the roots of the quadratic equation

Anastasy [175]

Answer:

${b}^{2} - 4ac = 0 \\ { ( - k - 2)}^{2} - 4(1)(4) = 0\\ {k}^{2} + 4k + 4 - 4 = 0 \\ {k}^{2} + 4k = 0 \\ k(k + 4) = 0 \\ \therefore \: k = 0 \: or \: k = - 4$

A phone company offers two monthly plans. Plan A costs 14 plus an additional 0.09 for each minute of calls. Plan B costs 18 plus

Sliva [168]

Answer:

200 minutes

Step-by-step explanation:

14 + 0.09 x = 18 + 0.07 x

0.09 x - 0.07 x = 18 - 14

0.02 x = 4

x = 400/2 = 200

Which direction does the graph of f(x) = −18 + x2 − 3x open?

Mekhanik [1.2K]

Please write this equation as <span>f(x) = −18 + x^2 − 3x

Rewrite it in descending order by powers of x: f(x) = x^2 - 3x - 18

Since the coefficient of the x^2 term is +, the graph opens UP.</span>

Find two consecutive even integers whose product is 288

Trava [24]

So I’m going to solve this using algebra OK?
So what you do is take the first integer as X.
Then we know that x(the first number) + X+2(the second number) is 288 right?
So we solve that saying x+x+2=288.
So 2X+2=288
2X+2-2=288-2 right?
So 2X=286.
So x is 286/2 right?
So x is 143.
Now the first number is 143 right?
So the second number should be 143+2 so 145.
I know they are not even but these are the solutions.
I don’t think there are any consecutive even numbers that add up to 288
