The graph of 15x + 7y = 15 is shown on the grid. which ordered pair is in the solution set of 15x + 7y ≥ 15? a) (0,-3) b) (-3,0) c) (3,3) d) (-3,-3)

Hello.

I took usatestprep.

Its c) (3,3)

Hope it helps.

: )

Step-by-step explanation:

The correct option is c.

Step-by-step explanation:

The given equation is

The given inequality is

A point will contained in solution set if the above inequality satisfied by that point.

Check the point (0,-3),

This statement is false, therefore option a is incorrect.

Check the point (-3,0),

This statement is false, therefore option b is incorrect.

Check the point (3,3),

This statement is true, therefore option c is correct.

Check the point (-3,-3),

This statement is false, therefore option d is incorrect.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
