1 answer:

Tatiana [17]3 years ago

Answer:

The answer to the first question is -12. The answer to the second question is 28. The answer to the third question is 16 meters apart.

Step-by-step explanation:

If the fish is 12 meters below sea level, its elevation is -12. If the sea bird is 28 meters above sea level, its elevation is 28. If the bird is directly above the fish, they are 16 meters apart because if you subtract 12 from 28 you get 16. I hope this helps you, have a wonderful day! :D

What is the solution to the system?<br> X+3y = 5<br> 5x-3y = 7

S_A_V [24]

Answer:

x + 3y = 5

5x - 3y = 7

Add up both equations, then:

6x = 12

=> x = 2

=> y = (5 - 2)/3 = 1

What are the solutions to the following system?

bija089 [108]

The solutions are $(\sqrt{2},-1) \text { and }(-\sqrt{2},-1)$ .

Solution:

Given equation:

$-2 x^{2}+y=-5$

Add $2 x^{2}$ on both sides.

$-2 x^{2}+y+2 x^{2}=-5+2 x^{2}$

$y=-5+2 x^{2}$ -------- (1)

$y=-3 x^{2}+5$ (given) -------- (2)

Equate (1) and (2).

$-5+2 x^{2}=-3 x^{2}+5$

Add $3 x^{2}$ on both sides.

$-5+2 x^{2}+3 x^{2}=-3 x^{2}+5 +3 x^{2}$

$-5+5x^{2}=5$

Add 5 on both sides.

$-5+5x^{2}+5=5+5$

$5x^{2}=10$

Divide by 5 on both sides, we get

$x^{2}=2$

Taking square root on both sides, we get

$x=\sqrt{2}, x=-\sqrt{2}$

Substitute $x=\sqrt{2}$ in (1).

$y=-5+2(\sqrt{2})^2$

$y=-5+4$

$y=-1$

Substitute $x=-\sqrt{2}$ in (1).

$y=-5+2(-\sqrt{2})^2$

$y=-5+4$

$y=-1$

Therefore the solutions are $(\sqrt{2},-1) \text { and }(-\sqrt{2},-1)$ .
