Find an ordered pair (x, y) that is a solution to the equation.<br><br> x-5y=5
timurjin [86]

Answer:

(x,y)=(0,-1)

Step-by-step explanation:

Observe that the equation x-5y=5 can be transformed in the equation of a line

x-5y=5\\-5y=5-x\\y=\frac{x-5}{5}\\y=\frac{1}{5}x-1

Since x can take any value then the equation has infinite solutions. But we need only an solution (x,y). Then, taking x=0 we have that y=\frac{1}{5}*0-1=-1.

Therefore the ordered pair (x,y)=(0,-1) is a solution of the equation.

Rewrite the equation by completing the square g(x) = x^2 - x - 6
borishaifa [10]

Answer:

g(x)=x2−x−6g(x)=x2-x-6

Set x2−x−6x2-x-6 equal to 00.

x2−x−6=0x2-x-6=0

Solve for xx.

Tap for fewer steps...

Factor x2−x−6x2-x-6 using the AC method.

Tap for more steps...

(x−3)(x+2)=0(x-3)(x+2)=0

If any individual factor on the left side of the equation is equal to 00, the entire expression will be equal to 00.

x−3=0x-3=0

x+2=0x+2=0

Set x−3x-3 equal to 00 and solve for xx.

Tap for more steps...

x=3x=3

Set x+2x+2 equal to 00 and solve for xx.

Tap for more steps...

x=−2x=-2

The final solution is all the values that make (x−3)(x+2)=0(x-3)(x+2)=0 true.

x=3,−2

Write the equation of the line through the points (4,5) and (12,9)
Umnica [9.8K]

Answer:

 y=1/2+1

Step-by-step explanation:

1) Y2-Y1 over X2-X1

<u>9-5=4</u>

12-4=8

4/8 simplify the answer= 1/2

m=1/2

2) subtitute the simplification to one of the points.

y=mx+b

5=1(4)+b

5=4=b

1=b

y=1/2+1
