Answer:
3x+35°-10
Step-by-step explanation:
remove the parentheses so the equation is
x+ 15°+x+20°+(x-10)
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.

Answer:
0
Step-by-step explanation:
The y-intercept always focuses on the y only. The x would be 0. If you were to do the x intercept, y would be 0. Vise versa.
