Mathematics

Answer:

Since we cannot find the square root of a negative number (at least not using the real number system), we cannot evaluate the formula any further. There will be no solutions. Use the discriminant to determine whether the quadratic equation has two, one, or no solutions. The result is a negative number. i really hope this helps u. good luck my dude

Answer:

equations have no real solution but have two complex solutions When  discriminant is negative.

Step-by-step explanation:

The quadratic equation ha 2 solution

let a, b and c are the coefficients of equation.

These 2 solutions are based on the value of discriminant,

<u>discriminant = square root (b^2 - 4ac) </u>

If b^2 - 4ac  is a negative value we cannot find its root.

The square root of a negative number is complex number.

Therefore equations have no real solution but have two complex solutions

Solve equation: <br> 8n-7=-12+3n
lutik1710 [3]

To solve this problem, the first thing we have to do is regroup the terms so that we can then subtract, simplify, subtract, and finally simplify again.

But first we must know.

<h3>¿What are the equations?</h3>

Equations are those mathematical equalities divided between two expressions which are called members and separated by their equal sign, in which known elements and unknown or unknown data appear, related by mathematical operations.

<h3>We solve the problem:</h3>
  • 8n - 7 = -12 + 3n
  • 8n - 7 = 3n - 12
  • 8n - 7 - 3n = -12
  • 5n - 7 = -12
  • 5n = -12 + 7
  • 5n = -5
  • N = -1

Now we must check our results.

8n -7 = -12 + 3n

8 × - 1 - 7 = -12 + 3 × - 1

- 8 - 7 = - 12 - 3

- 15 = - 12 - 3

- 15 = - 15

So, our results are correct, the answer is n = - 1

¡Hope this helped!

Patty can make 10 purses in 8 hours. At this rate how many purses can she make in 28 hours
Norma-Jean [14]
8 x 3 = 24 
24 + 4 = 28
Now if 10 purses are made in 8 hours, and we can see we timesed 8, 3 times, thats 10 x 3 = 30 
Now we take in to count the last 4 hours
30 + 4 = 34 
And 4 is half of 8 so if we cut 10 in half we get 5. 
So, the answer is 35
At least that's what I got :)

What is the reflection of image p(0,0) after two reflections first across x=-3 and
pochemuha
<span>P (0, 0) across x = -3 will change the x value. From 0 to -3 which is 3 units down, so the reflection will be another 3 units down ( points are the same distance from the reflection line) so the new x-value is -6 now just do the same thing for the y-value and you will get an image of P¹ ( -6, -6 ) </span>
