Answer:-1/9,1/27,-1/81
Step-by-step explanation:
We are dividing by -3 each time.
3/-3=-1
-1/-3=1/3
1/3÷-3=-1/9
-1/9÷-3=1/27
1/27÷-3=-1/81
Hi there! The answer is j = - 42.
In order to find the value of j, we need to set up and solve an equation.
The sum of j and 47 can be rewritten as
j + 47
The sum described above equals 5, so now we have all the information we know to set up the equation.
j + 47 = 5
Subtract 47 from both sides.
j + 47 - 47 = 5 - 47
j = - 42.
The answer is j = - 42.
~ Hope this helps you!
Using the discriminant of a quadratic equation, if the graph is translated shifted up 4 units, the graph will have no x-intercepts.
<h3>What is the discriminant of a quadratic equation and how does it influence the solutions?</h3>
A quadratic equation is modeled by:
The discriminant is:
The solutions are as follows:
- If , and it has 2 x-intercepts.
- If , it has 1 x-intercept.
- If , it has no x-intercepts.
In this problem, the function is given by:
f(x) = (x + 5)² - 3.
In standard form:
f(x) = x² + 10x + 22.
We want to find coefficient k for which the function has , then:
f(x) = x² + 10x + 22 + k.
The coefficients are a = 1, b = 10, c = 22 + k, hence:
10² - 4(22 + k) < 0
100 - 88 - 4k < 0
4k > 12
k > 3.
Hence, with k = 4, the function is shifted up 4 units, and the graph will have no x-intercepts.
