Question

Mathematics
1 answer:
tester [92]3 years ago
6 0

Answer:

Ø.

Step-by-step explanation:

Given the equation 7x^2 = -14. We are to find the value of x;

7x^2 = -14.

Divide both sides by 7

7x^2/7 = -14/7

x² = -2

Square root both sides

√x² = ±√-2

x = ±√2 i

The value of x is (-√2 i, √2 i)

Since there values is a complex values, hence there is no real solution. The answer is Ø.

La un supermarket sau vandut intro zi 32kg de banane si 86kg de portocale incasanduse 536 lei a doua zi sau vandut 96 kg de bana
Shtirlitz [24]

Answer:

the banana cost per kg is 6 and for orange it is 4

Step-by-step explanation:

The computation is shown below:

Let us assume the banana be x

And, the oranges be y

Now according to the question

There would be two equations

32x + 86y = 536.......(1)

96x + 52y = 784.........(2)

Now multiply by 3 in equation 1

96x + 258y = 1,608

96x + 52y = 784

258y - 52y = 1608 - 784

206y = 824

y = 4

And, the x would be

32x + 86(4) = 536

32x + 344 = 536

x = 6

Hence, the banana cost per kg is 6 and for orange it is 4
