Answer:

All real numbers less than or equal to 3
Step-by-step explanation:
we have

Solve for y
Subtract 2y both sides


The solution is the interval ------> (-∞,3]
All real numbers less than or equal to 3
In a number line the solution is the shaded area down of y=3 (close circle)
see the attached figure
Answer:1.5
Step-by-step explanation:
Answer:
The discriminant is -7
Step-by-step explanation:
The discriminant of a quadratic function/equation(ax^2+bx+c = 0) is calculated as:

Here
b is the co-efficient of x
a is the co-efficient of x^2
and c is the constant
Given equation is:

Here
a = -2
b = 5
c = -4
Putting the values in the formula for discriminant

As the discriminant is negative, the equation has no real solution.
Hence,
The discriminant is -7
