Answer:

When we have a quadratic equation:

a*x^2 + b*x + c = 0

There is something called the determinant, and this is:

D = b^2 - 4*a*c

If D < 0, then the we will have complex solutions.

In our case, we have

5*x^2 - 10*x + c = 0

Then the determinant is:

D = (-10)^2 - 4*5*c = 100 - 4*5*c

And we want this to be smaller than zero, then let's find the value of c such that the determinant is exactly zero:

D = 0 = 100 - 4*5*c

    4*5*c = 100  

       20*c = 100

            c = 100/20 = 5

As c is multiplicating the negative term in the equation, if c increases, then we will have that D < 0.

This means that c must be larger than 5 if we want to have complex solutions,

c > 5.

Answer:

x = 1 and y = 7

Step-by-step explanation:

First, you substitute the y into the first equation

-5x+2(7x)=9

-5x+14x=9

9x=9

x=1

Then put the x into the equation to find y

This is if you substitute using the second equation

y=7(1)

y=7

Answer:

2n-4

Step-by-step explanation:

The value of n for the given condition is 2(n - 2).

To simplify means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue. By eliminating all common factors from the numerator and denominator and putting the fraction in its simplest/lowest form, we can simplify fractions.

Given equation

(n + 8) + (n − 12) =

n + 8 + n - 12

solving constant separately and variables separately,

2n - 4

the common factor of 2 and 4 is 2

2(n - 2)

Hence the simplified form of an equation is 2(n - 2).

Its not an function.

Step-by-step explanation:

If each input value leads to only one output value, classify the relationship as a function.

Answer:true

Step-by-step explanation:

Answer:

In order to out a fraction in lowest terms, you must divide by the Greatest Common Factor, or GCM, of the numerator and denominator in the fraction. Let's say we have the fraction 25/100. We know that the greastest common factor of 25 and 100 is 25, as 25 ÷ 25 = 1 and 100 ÷ 25 = 4 so 25/100 in lowest terms is 1/4:

25        25       1

___  ÷ ___ = ___

100      25       4

If the GCM of a fraction equals 1, the fraction is simplified. Because the only common factor of 1 and 4 is 1, we know this fraction is simplified.

1        1         1

__ ÷ ___ = ___

4        1        4

Answer:

-[tex]17^\circ F[/tex]

OR

[tex]17^\circ F[/tex] decrease in the temperature.

Step-by-step explanation:

Given that:

Temperature at the night  = [tex]12^\circ F[/tex]

Temperature in the morning = -[tex]5^\circ F[/tex]

To find:

The total difference in the temperature = ?

Solution:

Difference of any quantity is given by the Final value of quantity minus Initial value of quantity.

Therefore, the difference is given as : -[tex]5^\circ F[/tex] - [tex]12^\circ F[/tex] = -[tex]17^\circ F[/tex]

Negative value in the difference indicates that there is a decrease of the quantity.

So, the answer is:

Answer

577.68

Step-by-step explanation:

first you subtract 60 from 170.50 to get 110.5. After that you multiply by 4 to get 442. take 442 and add it to 135.68 to get 577.68. so it would look like this

170.500-60=110.5 110.5 x 4=442  442+135.68=577.68

Answer:

y= -1/4x + 14

Step-by-step explanation:

- the slope of a perpendicular line is the negative reciprocal of the original line, so the slope of the new line is -1/4

- now, y= -1/4 x + c, to find c we substitute the values of x and y from the given point [ (8,12) ]

- (12) = -1/4*(8) + c, after you rearrange you get c = 14

- place the value of c to get y= -1/4x + 14

Determine the length of one side after translation

It should be noted that when a shape, line, object is being translated by shifting its position, only the position of the shape, line or object changes not its length

This implies that, the length of the sides of the equilateral triangle remain unchanged.

Hence:

[tex]Sides= 7\ units[/tex]

Answer: 2x + 0.5 unit

Step-by-step explanation:

A square has 4 equal sides. Therefore, its perimeter is calculated by adding the four sides.

Since the perimeter of a square is 8x +2 units, to get the length of one side, we divide the perimeter by 4. This will be:

= (8x + 2)/4

= 2x + 0.5

Therefore, the length of one side is 2x + 0.5 unit

So the graph is translated 2 units right and 3 units up.

Answer:

x = 81, y = 68, z = 99

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Consider the triangle on the left, then

x = 180 - (36 + 63) = 180 - 99 = 81

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an exterior angle of the triangle on the right, thus

13 + y = x , that is

13 + y = 81 ( subtract 13 from both sides )

y = 68

Consider the triangle on the right

z = 180 - (13 + y) = 180 - (13 + 68) = 180 - 81 = 99

Answer:

The answer will be 8.38709677419

The measure of each numbered angles are ∠1 =  56°, ∠2 = 56° and ∠3 = 74°.

An angle for any figure is formed by two rays which joins at a common point called vertex or node.

Usually angles are measured in degrees or radians.

Consider triangle PMQ

The sum of the interior angles of a triangle is 180°.

∠MPQ + ∠QMP + ∠PQM = 180°

58° + 66° + ∠1 = 180°

∠1 =  180° - (58° + 66°)

∠1 =  180° - 124°

∠1 =  56°

Now, ∠1 and ∠2 are vertically opposite angles. Hence they are equal.

∠2 = 56°.

Again, for triangle NQO

∠2 + ∠3 + 50° = 180°

56° + ∠3 + 50° = 180°

∠3 = 180° - (50° + 56°)

∠3 = 180° - 106°

∠3 = 74°

Hence ∠1, ∠2 and ∠3 are 56°, 56° and 74° respectively.
