Answer:
k<0 or k>4
Step-by-step explanation:
In the generic equation ax² + bx + c = 0, there are two solutions only if discriminant D>0 where D = b²-4ac.
Mapping your equation on the generic means that:
a = k
b = k
c = 1
So when we have to solve D>0 we solve:
k² - 4k > 0
k(k-4) > 0
roots are k=0 and k=4
k² - 4k > 0 when k<0 or k>4
500 - 116 = 384 left to collect
384 divided into 3 weeks = 128
They must collect $128 per week in order to reach their goal of $500.
Answer: <em>-2 is the correct answer </em>
Step-by-step explanation: All the other values in the options represent an input (x) instead of an output f(x). Al the values in the chart that are on your left are x inputs and all the values on the right are f(x) outputs Leaving you with -2 as the only correct answer.
<em>Hope this helps have a good one!</em>

The inequality that models this situation is 150x + 350 y ≤ 250000 and x + y < 1200
<h3>What is an
inequality?</h3>
An inequality is an expression that shows the non equal comparison of two or more numbers and variables.
Let x represent the number of wheat acres and y represent the number of corn acres, hence:
150x + 350 y ≤ 250000 (1)
Also:
x + y < 1200 (2)
The inequality that models this situation is 150x + 350 y ≤ 250000 and x + y < 1200
