Answer:

3x-y=1 is in the form Ax+By=c

where A=3, B=-1, C=1

Step-by-step explanation:

we have to convert the equation y-5=3(x-2) to the form Ax + By = C.

the equation y-5=3(x-2) is in the form y-y_{1} =m(x-x_{1} )

which is the point slope form of a straight line in cartesian coordinate.

where m is the slope of the line and x_{1} ,y_{1} is the point through which the line is passing through.

therefore y-5=3(x-2) becomes y-5  = 3x-6

y-5+6=3x

y+1=3x

3x-y=1

this equation is in the form Ax+By=c

therefore comparing these two equations we get

A=3, B=-1, C=1

The price of tiling a room varies directly as the size of the room. Sam is laying tile in his kitchen. If the tiling costs $4,22
mixas84 [53]

Answer:

239 ft².

Step-by-step explanation:

Let P represent the price for tiling.

Let S represent the size of the room.

From the question,

Price (P) varies directly as the size (S) i.e

P & S

P = KS

Where K is the constant of proportionality.

Next, we shall determine the value of K as follow

Price (P) = $ 4224

Size (S) = 264 ft²

Constant of proportionality (K) =?

P = KS

4224 = K × 264

Divide both side by 264

K = 4224/264

K = 16

Finally, we shall determine the size of the kitchen that will cost $ 3824 for tiling.

This is illustrated below:

Price (P) = $ 3824

Constant of proportionality (K) = 16

Size (S) =?

P = KS

3824 = 16 × S

Divide both side by 16

S = 3824/16

S = 239 ft²

Therefore, the size of the kitchen is 239 ft².

mojhsa [17]

Answer:

Sometimes this fraction can be further simplified by dividing the numerator and the denominator by their greatest common factor. ... Divide the numerator by this number. If the result is zero, the simplified slope of the line is also zero.
