What is the solution to the equations x^2-2x+y=8 and x-y=-2

1 answer:

6 0

Hello!!

For the first equation:

$-2x + x^2 + y = 8$ (Solve for y)

$y = -x^2 + 2x +8$

For the second equation:

x - y = -2 (Solve for y)

-y = -x - 2

-y = x + 2

Good luck :)

Answer: 1. ∠A= 80.75° 2. 41.79 $cm^2$

Step-by-step explanation:

Since, According to the sines low,

$\frac{sin A}{CB} = \frac{sin C}{AB}$

Here, CB= 4.1 cm, AB = 3.3 and ∠ C = 52.6°

$\frac{sin A}{4.1} = \frac{sin 52.6}{3.3}$

⇒ $sin A = 4.1\times\frac{sin 52.6}{3.3}$

⇒ $sin A =0.98699998308$

⇒ A = 80.75°

2. Since, the area of the given figure = Area of the rectangle having dimension 8.3 × 4.2 + Area of the half square of radius 2.1

=34.86 + 6.93

= 41.79 square cm

The temperature in Bloomington on Sunday was 32.6°C. On Monday, the temperature changed by -8.25°C. What was the temperature on

ser-zykov [4K]

I believe it is 24.35 degrees celsius. i believe this because if you subtract the temperature on sunday 32.6 by the temperature number that they said changed -8.25 you get 24.35

Rate of change: 1:5

Equation: x · 5 = y

Is this relationship proportional? Yes

How do you know? I know, because the table never doesn't follow the equation.

Rate of change: 1:1

Equation: x · 1 = y

Is this relationship proportional? Yes
