Answer:
(B) -1/5
Step-by-step explanation:
Answer:
w + 2.3 > 18
Step-by-step explanation:
w + 2.3 is the representation of a number w added to 2.3. We also know that this is more than (>) 18. Overall this can be represented by:
w + 2.3 > 18
1/3 is the answer I believe

By using the definition of <em>second order</em> polynomials and the discriminant from <em>quadratic</em> formula, we conclude that the values of k must be less than 1/4.
<h3>How to determine the value of k such that a line intersects a quadratic equation</h3>
In this question we must determine the set of values of k such that the function g(x), a <em>linear</em> function, intersects a<em> quadratic</em> function f(x) at two points. In this case, we must solve the following <em>second order</em> polynomial:
k · x² + 4 · x - 3 - g(x) = 0
k · x² + 4 · x - 3 - 2 · x + 7 = 0
k · x² + 2 · x + 4 = 0
In this case, the discriminant of the equation described above must be <em>positive</em>:
2² - 4 · k · 4 > 0
4 - 16 · k > 0
4 > 16 · k
16 · k < 4
k < 1/4
By using the definition of <em>second order</em> polynomials and the discriminant from <em>quadratic</em> formula, we conclude that the values of k must be less than 1/4.
