Y=-x+5 Y=x+1 Solve the system

Elis [28]

Answer:

$y = - x + 5 \\ y = x + 1 \\ - x + 5 = x + 1 \\ - 2x = - 4 \\ x = 2 \\ y = 2 + 1 = 3 \\ y = 3$

Therefore the answer is:

x=2; y=3

Good luck!

Montana is known for having very chilly winters. One night, the temperature was falling by 2 degrees Fahrenheit each hour. At su

Kipish [7]

Answer:

7 hours

Step-by-step explanation:

We are given that

At sunset, the temperature=-5 degrees Fahrenheit

Each hour, temperature falling=2degrees Fahrenheit

We have to find time taken to reach the temperature -19° F.

Let x be the time time taken to reach the temperature -19° F

According to question

$-5+x(-2)=-19$

Where we taking 2 negative because temperature decreases.

$-5-2x=-19$

$-5+19=2x$

$14=2x$

$x=\frac{14}{2}$

$x=7$

Hence, it will take 7 hours for the temperature to reach -19° F.

The given figure shows a vertical hyperbola with its centre at origin, and as we observe the figure, we can conclude that :

Length of transverse axis is :

$\qquad \sf \dashrightarrow \: 2b = 12$

$\qquad \sf \dashrightarrow \: b = 6$

length of conjugate axis is :

$\qquad \sf \dashrightarrow \: 2a = 8$

$\qquad \sf \dashrightarrow \: a = 4$

Equation of hyperbola ~

$\qquad \sf \dashrightarrow \: \cfrac{ {y}^{2} }{ {b}^{2} } - \cfrac{ {x}^{2} }{ {a}^{2} } = 1$

plug in the values ~

$\qquad \sf \dashrightarrow \: \cfrac{ {y}^{2} }{ {6}^{2} } - \cfrac{ {x}^{2} }{ {4}^{2} } = 1$

$\qquad \sf \dashrightarrow \: \cfrac{ {y}^{2} }{ {36}^{} } - \cfrac{ {x}^{2} }{ {16}^{} } = 1$
