Is the equation conditional, an identity, or a contradiction? y - 11 + 3y = 6y + 4
ipn [44]

Answer:

The equation is a conditional.

y = 7.5

Step-by-step explanation:

y - 11 + 3y = 6y + 4

4y - 11 = 6y + 4

4y - 4y - 11 = 6y - 4y + 4

- 11 = 2y + 4

- 11 - 4 = 2y + 4 - 4

2y = - 15

2y ÷ 2 = - 15 ÷ 2

y = - 7.5

Find the equation of the line that goes through ( 2, 4 ) and ( 4, 6 ).
Mrrafil [7]

Answer:

y=x+2

m=(y2-y1)/(x2-x1)

m=(6-4)/(4-2)

m=2/2

m=1

y-y1=m(x-x1)

y-4=1(x-2)

y=x-2+4

y=x+2

Marlon bought 7/8 pound of turkey at the deli. he used 2/3 of it to make sandwiches for lunch. How much of the turkey did Marlon
OLga [1]
So 2/3 as a decimal would be 0.66 and 7/8 as a decimal would be 0.125 so if you subtract the 2 decimals it would give you the answer of 49 slices.

i hope i'm right! :)
