First you have to solve for y on both equations
-4x -3y = 4
-3y = 4x + 4
y = -4/3 x + -4/3

4x - y = -4
-y = -4x -4
y = 4x + 4

If you graph these equations you will find out that the answer is C.

Answer:

The answer is below

Step-by-step explanation:

1) 708 mm

1000 mm = 1 m

708\ mm=708\ mm*\frac{1\ m}{1000\ mm}=0.708\ m

2) 15.6 km

1 km = 100 dam

15.6\ km=15.6\ km*\frac{100\ dam}{1\ km}=1560\ km

3) 108 cc

1 cc = 1 ml

108\ cc=108\ cc*\frac{1\ ml}{1\ cc}=108\ ml

4) 8 tbsp

1 tbsp = 14.7868 ml

8\ tbsp=8\ tbsp*\frac{14.7868\ ml}{1\ tbsp} =118.294\ ml

5) 16.5 L

1 L = 0.264172 gal

16.5\ L=16.5\ L *\frac{0.264172\ gal}{1\ L} =4.56\ gal\\\\

6) 3569 sec

1 day = 86400 sec

3569\ sec=3569\ sec*\frac{1\ day}{86400\ sec}=0.04\ day\\\\

7) 4 score

1 score = 240 months

4\ score=4\ score*\frac{240\ month}{1\ score}=960\ month

8) 299 K

Celsius = kelvin - 273.15

Celsius = 299 - 273.15 = 25.85 °C

9) 200 °F

Celsius = (farenheit - 32) * 5/9

Celsius = (200 - 32) *5/9 = 93.33 °C

10) 10866 mg

1 kg = 1000000 mg

10866\ mg= 10866\ mg*\frac{10^6\ kg}{1\ mg}=0.10866\ kg

You get a 180-day $3,000 consumer loan at 9% interest You are required to pay a $100 setup fee at the time you get the loan. Bas
Naya [18.7K]
The interest on the loan is
.. I = P*r*t = 3000*.09*180/365 = 133.15

Your effective rate is
.. r = I/(Pt) = (100 +133.15)/(3000*180/365) = 15.8%

The general form of a circle is given as x^2+y^2+4x-10y-7=0.
mylen [45]

Answer:

  • center: (-2, 5)
  • radius: 6

Step-by-step explanation:

We can complete the squares of the x- and y-terms by adding the square of half the linear term coefficient.

  (x^2 +4x) +(y^2 -10y) = 7

  (x^2 +4x +4) +(y^2 -10x +25) = 7 + 4 + 25

  (x +2)^2 +(y -5)^2 = 6^2

Compare to ...

  (x -h)^2 +(y -k)^2 = r^2 . . . . . standard form equation of a circle

We see that the center is ...

  (h, k) = (-2, 5)

and the radius is ...

  r = 6

Can someone please help me ☹️
Vadim26 [7]

Answer:

When c = 6 and d = 34, there is one solution. When c = 8 and d = 6, there is no solution. When c = 8 and d = 12, there are infinitely many solutions.

Step-by-step explanation:

6x + 34 = 8x +12

-6x          -6x

34 = 2x +12

-12         -12

22 = 2x

11 = x

8x + 6 = 8x +12

-8x        -8x

6 = 12

No solution

8x+12= 8x + 12

-8x-12  -8x - 12

0 = 0

Infinite solutions
