Answer:
I'm pretty sure it is (2,0)
In this month spider ate 10 bugs.
Step-by-step explanation:
Given,
The spider ate 25% more bugs than last month.
It ate 8 bugs in last month.
To find the number of bugs it ate this month.
<u>Solution</u>
It ate more bugs = 8×25%
=8×
= 2
In this month it ate = 8+2 = 10 bugs.
The values of x that will give the quadratic equation no real number solutions are -5 and 9
<h3>What are real roots of a quadratic equation?</h3>
Real roots of a quadratic equation are values of x, whose numbers can be represented on a number line.
Analysis:
We have -
+3x +c = 0
- 4ac is called the discriminant of a quadratic equation.
if
- 4ac < 0, then the quadratic equation has no real root.
where a = -1, b = 3 c = c
-4(-1)c < 0
9 + 4c < 0
4c < -9
c < -9/2
Which means values lower than -9/2 would give the solution no real root.
From, the options, only -5 would give no real solution, since it is lower than -9/2.
