Step-by-step explanation:

x + 3y = 9

-2x + 2y = 6

2x + 6y = 18

-2x + 2y = 6

0 + 8y = 24

8y = 24

y = 3

x + 3y = 9

x + 3(3) = 9

x + 9 = 0

x = 0

x = 0

x = 0y = 3

Solve for y then find the slope and y intercept and graph <br> y=4x+3<br><br> y=<br> b=<br> m=
Ugo [173]

Answer:

y = 4x+3

m =4

b =3

Step-by-step explanation:

y=4x+3

This is already solved for y

This is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

y = 4x+3

m =4

b =3

What is 6/a-6 = 3/a-3 ?<br> help me please
Alenkasestr [34]

Answer:

a=1

Step-by-step explanation:

Multiply all terms by a and cancel:

6+−6a=3+−3a

−6a+6=−3a+3(Simplify both sides of the equation)

−6a+6+3a=−3a+3+3a(Add 3a to both sides)

−3a+6=3

−3a+6−6=3−6(Subtract 6 from both sides)

−3a=−3

−3a

−3

=

−3

−3

(Divide both sides by -3)

a=1

If the hypotenuse of a right triangle is 8 and one leg is 6, what is the length of the other leg?
qwelly [4]

Answer:

5.3

Step-by-step explanation:

pythagorean theory :,)

a^{2} + b^{2} = c^{2}

the legs are a and b, while the hypotenuse (the longest side) is c

fill in the equation with the information u have and simplify so

a^{2} + 6^{2} = 8^{2}

a^{2} + 36 = 64

now get the variable (a) by itself

a^{2} + 36 = 64\\

(subtract 36 on both sides)

a^{2} = 28

a = 5.3

square root of both sides ≈ 5.3

(you could also multiply the square root of 7 by 2)
