What is the nature of roots of the quadratic equation 5x² 2x 3 0?.

A quadratic equation has the generic form ax2 + bx + c = 0. Thus, the roots are hypothetical, meaning that they have two false roots.

The equation's nature of roots indicates whether it contains rational, irrational, or fictitious roots. Imaginary roots and unreal roots are synonyms.

Having just second-order terms, the quadratic form is a unique nonlinear function (either the square of a variable or the product of two variables).

2x2 - 3x + 5 = 0

a = 2 , b = -3, c = 5

b2 - 4ac = (- 3)2 - 4 (2) (5) (5)

= 9 - 40

= - 31

b2 - 4ac < 0

Therefore, the equation lacks any true roots.

Answer:

193 minutes

Step-by-step explanation:

We know

Boris paid an $8 fee to start the scooter plus 6 cents per minute of the ride.

Let y represent the total cost and x represent the number of minutes we have the equation

y = 0.06x + 8

Now, put $19.58 in for y and solve

19.58 = 0.06x + 8

11.58 = 0.06x

x = 193 minutes

So, Boris rides the scooter for 193 minutes.

A circle is formed when every point in the plane that is a specific distance apart from another point does so (center). Thus, it is a curve made up of points that are separated from one another by a set distance while moving in the plane. It is also rotationally symmetric about the center at all angles. A circle is a closed, two-dimensional object where each pair of points in the plane is equally separated from the "center." A specular symmetry line is made by drawing a line through the circle. It is also rotationally symmetric about the center at all angles.

There are several ways to find the measure of an angle in a triangle, depending on the information given about the triangle and the angles. Some common methods include:

Using the angles in a triangle sum to 180 degrees: If you know the measures of two angles in a triangle, you can use the fact that the angles in a triangle sum to 180 degrees to find the measure of the third angle.

Using the Pythagorean theorem: If you have a right triangle, you can use the Pythagorean theorem to find the measure of the right angle (90 degrees)

Using the Law of Cosines: If you know the measures of two angles and the lengths of all three sides of a triangle, you can use the law of cosines to find the measure of the third angle.

Using trigonometry: If you know the lengths of two sides of a triangle and the measure of one angle, you can use trigonometry to find the measure of the other angles.

It is important to note that in order to find the measure of an angle you need to know at least one angle and the values of the sides of the triangle or two angles.

Answer:

C. 48

Step-by-step explanation:

BC = 30

30 + 18 = AC

AC = 48

The solution of the given linear equations is (x,y) = (1,-1).

The given linear equations are

8x + 3y = 5 - - - ( 1 )

3x - 2y = 5 - - - ( 2 )

As the RHS of both equations is equal, equating the LHS of both equations, we get,

8x + 3y = 3x - 2y

⇒ 8x - 3x = - 2y - 3y

⇒ 5x = - 5y

⇒ x = - 5y ÷ 5

⇒ x = - y

By substituting x = - y in equation ( 1 ), we get,

8x + 3y = 5 - - - ( 1 )

⇒ 8 ( - y ) + 3y = 5

⇒ - 8y + 3y = 5

⇒ - 5y = 5

⇒ y = - 5 ÷ 5

⇒ y = - 1

Now,

x = - y

⇒ x = - ( - 1 )

⇒ x = 1

An x-y (or bivariate) plot is any graph or plot with two axes. The "x-axis" is typically the horizontal axis, whereas the "y-axis" is typically the vertical axis.

Your plot's axes should be identified, and the scale should be chosen (if the graph is not already labeled). Plot the first two pairs of numbers first (the top row of numbers).

Finding the number a on the horizontal, or x-, axis and tracing up or down from there while maintaining a parallel path to the vertical, or y-, axis, will allow you to draw the point at (a, b) on the Cartesian plane.

The position of the point is this area (a, b). The intersection of the two axes defines the plane's center. It is referred to as the beginning or point (0,0).

Each axis is further subdivided into equal units starting at the origin: rising, positive numbers on the x-axis and up the y-axis; falling, negative numbers on the x-axis and down the y-axis.

Answer:

30 tiles

Step-by-step explanation:

We know

First store

$0.59 per tile

Rent a tile saw for $18

Second store

1 tile = $1.19

We have the equation

0.59x + 18 = 1.19x

18 = 0.6x

x = 30 tiles

So, she must buy 30 tiles for the same cost at both stores.

Answer:

Margo must purchase 30 tiles for the cost to be the same at both stores.

Step-by-step explanation:

By analyzing the "real-world" problem, we can convert the words into two algebraic equations.

Store 1:

"$0.59 per tile and rent a tile saw for $18."

y = 0.59x + 18

y = the price of the tiles bought

0.59 = price of one tile

x = number of tiles

18 = the fixed cost of a saw

Store 2:

"At another store, she can borrow the tile saw for free if she buys tiles there for $1.19 per tile."

In this case, the saw is free. Thus, we don't need to add a price to the equation.

y = 1.19x

y = the price of the tiles bought

1.19 = price of one tile

x = number of tiles

Now that we have both equations, we can write down the equations that equate other. This formula will indicate that the equations would intersect at a certain point on the x and y values. Hence, this step will answer how many tiles are required for both stores to equal the same price.

[tex]0.59x+18=1.19x[/tex]

Now solve for x:

[tex]0.59x-0.59x+18=1.19x-0.59x\\\\18=0.6x\\\\\frac{18}{0.6} =\frac{0.6x}{0.6}\\\\30=x[/tex]

Margo can buy 30 tiles from both stores for the cost to be equal.

You might ask, "But what about the price?" This is where we solve for y; this variable will answer how much the tiles would cost at 30 tiles. So, we can take the answer for "x" and plug it into any of the two equations.

[tex]y=1.19x\\y=1.19(30)[/tex]

For this equation, all you have to do is multiply both numbers to get your answer.

[tex]y=35.7[/tex]

Therefore, Margo can buy 30 tiles for the cost to be same at both stores at $35.70.

Answer:

x = -3

y = 5

Step-by-step explanation:

3x + 2y = 1

5x + 4y = 5 ​

First, we multiply the first equation by -2

-6x -4y = -2

5x + 4y = 5

-x = 3

x = -3

Now put -3 back in for x and solve for y

3(-3) + 2y = 1

-9 + 2y = 1

2y = 10

y = 5

Let's check

3(-3) + 2(5) = 1

-9 + 10 = 1

1 = 1

So,  x = -3 & y = 5 is the correct answer.

The prime factorization of the number 21 is:

21 = 3*7

We want to write the prime factorization of 21.

To do so, we just need to divide the number by prime numbers.

The first prime number we can try is 2, if we divide by 2 we get:

21/2 = 10.5

This is not an integer, so 2 is not a factor.

The next one is 3:
