The answer is 361.

This is because you take 731 and subtract 9 and you get 722. Then you divide 722 by two and you get 361.

Answer: y=0 and x=3

Step 1: Solve for x in 2x+9y=6.

2x+9y=6

2x=6-9y (Subtract 9y from both sides)

x=3 - 4.5y( Divide both sides by 2)

Step 2: Replace x with 3-4.5y

-7x - 8y = -21\\-7(3-4.5y) - 8y = -21\\

Step 3: Solve for y

(-21)+31.5y-8y=(-21) (By looking at this, we can determine that y=0)

Step 4: Replace y with 0

2x+9y=6\\2x+9(0)=6\\2x=6\\

x=3 (Divide both sides 2)

Therefore, y=0 and x=3

The equation of line S is y = 8x − 7 .
LenKa [72]

Answer:

y = 8x + 9

Step-by-step explanation:

Parallel lines have the same gradient,

So m = 8

y = 8x + c

When x = -1 ,y = 1

1 = 8(-1) + c

c = 9

y = 8x + 9

Find (f/g)(x) f(x)=4x+1 g(x) =3x-4
mash [69]
Your answer is very close to being correct; however, the true answer is actually \frac{4x+1}{3x-4} without any parenthesis needed around the fraction. Notice how there is no (x) at the end.
