What is the value of the discriminant of the quadratic equation −1 = 5x2 −2x, and what does its value mean about the number of r
joja [24]
The correct answer for this question is "The discriminant is equal to −16, which means the equation has no real number solutions."

<span> −1 = 5x2 −2x
</span><span>5x2 −2x + 1 = 0
</span>
To get the discriminant value, use this formula
= b^2 - 4ac
= (-2)^2 - 4(5)(1)
= 4 - 20
= -16

Give the values of Xmin, Xmax, Ymin, and Ymax for the screen, given the values for Xscl and Yscl.
joja [24]

Answer: Option C.

Step-by-step explanation:

Xmin, Xmax, Ymin, and Ymax represent the minimum/maximum values that X and Y can take.

We know that the scale in Y and X is 10.

This means that each mark in each axis represents 10 units.

Now, let's go to the vertical axis (y-axis)

Counting from the (0, 0) we can count:

4 marks up

4 marks down.

So if each mark represents 10 units, 4 marks are 40 units.

Then the range for Y is {-40, 40}

Now for the horizontal axis.

We can count 3 marks on each side, and with the same reasoning as before, we can find that the range for X is: {-30, 30}

Then we have that:

Xmin = -30

Xmax = 30

Ymin = -40

Ymax = 40

Now, as a point is defined as (X, Y)

This region can be written as:

{Xmin, Xmax} by {Ymin, Ymax}

or, replacing the values:

{-30, 30} by {-40, 40)

So the correct option is C.
