Step-by-step explanation:
0.5 ( r + 2.75 ) = 3
r + 2.75 = 3 / 0.5
r + 2.75 = 6
r = 6 - 2.75
r = 3.25
Answer: It has two distinct real zeros.
Step-by-step explanation:
The formula that is used to calculate the discriminant of a Quadratic function is the one shown below:

In this case you have the following Quadractic function provided in the exercise:

Let's make it equal to 0:

You can identify that:

Knowing these values, you can substitute them into the formula and then evaluate:

Therefore, since:

You can determine that the it has two distinct real roots.
Answer:
<h3>w=xa</h3>
Step-by-step explanation:
Rewrite the equation as w/a=x
w/a=x
Multiply both sides of the equation by a
w=x*(a)
Multiply x by a
w=xa
