What is the value of y in the system of equations 6x-y=2 and 4x-y=-8
uysha [10]

Answer:

y=28

Step-by-step explanation:

6x-y=2

-y=2-6x

y=6x-2

4x-(6x-2)=-8

4x-6x+2=-8

-2x=-10

x=5

y=6*5-2=30-2=28

y=28

Which of the following quantities are directly proportional:
Zepler [3.9K]

Answer:

Area ∝ Length.

Step-by-step explanation:

If the length of a rectangle is L and width is W, then the area of the rectangle is given by A = LW.

Now, it is given that the width of a rectangle is constant and it is 6 cm.

Therefore, the relation between the length of the rectangle in cm with the area of the rectangle in cm² will be A = 6L.

So, it is clear from the above relation that Area (A) is proportional with its length (L) and the constant of proportionality is 6. (Answer)

12x +7 < −11 OR 5x −8 > 40
r-ruslan [8.4K]

For this case we must resolve each of the inequalities and find the solution set.

Inequality 1:

12x + 7

We subtract 7 from both sides of the inequality:

12x

We divide between 12 on both sides of the inequality:

x

Thus, the solution is given by all values of x less than- \frac {3} {2}.

Inequality 2:

5x-8> 40

We add 8 to both sides of the inequality:

5x> 40 + 8\\5x> 48

We divide between 5 on both sides of the inequality:

x> \frac {48} {5}

Thus, the solution is given by all values of x greater than\frac {48} {5}.

The solution set is given by:

(-∞, - \frac {3} {2}) U (\frac {48} {5},∞)

Answer:

(-∞, - \frac {3} {2}) U (\frac {48} {5},∞)
