The curve y= (k+2)x^2 meets the line y=(k+3)x +3. Find the range of possible values of k.

Greeley [361]

$(k+2)x^2=(k+3)x+3\\
(k+2)x^2-(k+3)x-3=0\\
\Delta\geq0 \wedge k\not=-2\\
\Delta=(-(k-3))^2-4\cdot(k+2)\cdot(-3)\\
\Delta=(-k+3)^2+12k+24\\
\Delta=k^2-6k+9+12k+24\\
\Delta=k^2+6k+33\\
k^2+6k+33\geq0\\
\Delta=6^2-4\cdot1\cdot33=36-132=-9$

You have a dog-walking business. You charge $12 per hour. Let's define n as the amount you earn and h as the number of

Goshia [24]

Answer:

$n = 12h$

Step-by-step explanation:

Given

$r = 12/hr$ --- rate

$h \to hours$

$n \to amount$

Required

Determine which solution is correct or incorrect

The solutions are not given. So, I will provide a general explanation

The amount (n) is calculated as:

$n = r * h$

So, we have:

$n = 12 * h$

$n = 12h$

The above is the general equation to solve for the amount, given h hours

When h = 2.5, we have:

$n = 12*2.5$

$n = 30$
