the answer is c
the y-intercept is 10–it doesn’t have a negative sign, so it is positive
Answer:
the graph
Step-by-step explanation:
hi there hope this helps
1) A quadratic will have no real roots when its discriminant is negative


Dividing by 4,

We have a positive coefficient on k^2 so this parabola is a CUP (concave up positive) so has a minimum at the vertex. If the vertex y value is less than zero, the inequality will be true in the range between the zeros.

That's true for

2) We look for the meet of the line and the parabola:


For two intersections we need a positive discriminant:



That's means two negative or two positive, so
or 
Answer:
D is the correct answer.
Step-by-step explanation:
-Subtract final value by start value
-Divide by start value
-Multiply by 100
The measure of angle C is 60 degrees. All the angles have to equal 180 degrees when added together. Since there is one right angle, 90 degrees, and one 30 degree angle, the last angle can only equal 60 degrees.
