Mathematics
1 answer:
konstantin123 [22]3 years ago
8 0

Answer:

(2,4)

Step-by-step explanation:

y = 4x - 4

2x + 3(4x - 4) = 16

2x + 12x - 12 = 16

14x = 28

x = 28/14

x = 2

y = 4(2) - 4

y = 8 - 4

y = 4

Which ordered pair is in the solution set of 0.5x – 2y > 3?
Sholpan [36]

Answer:

See Below

Step-by-step explanation:

The left side of the equation HAS TO BE GREATER THAN 3

So we take each ordered pair (x,y), plug it into the expression of left side of inequality and see which one is GREATER THAN 3. That's our answer.

A:

0.5x - 2y

0.5(-2) -2(0.5) = -2

NO

B:

0.5x - 2y

0.5(2) -2(1) = -1

NO

C:

0.5x -2y

0.5(2) -2(-1) = 3

NO

D:

0.5x -2y

0.5(-2) -2(-0.5) = 0

NO

None of them are solutions. C would have been a solution if the inequality had an "EQUAL SIGN" -- but it doesn't. Maybe the question is wrong, but if the question is right, then there is no correct answer.
