Which values of x and y are solutions to the open sentence?

OpenStudy (kaylardz0405):

\[5y \ge 3x+4\]

OpenStudy (danjs):

Since you have one equation with 2 variables, you can not solve for a specific solution, the answer will have restrictions

OpenStudy (danjs):

solve for Y, and say , all Y , such that, ygreater than or equal to .....

OpenStudy (kaylardz0405):

A. x = 1, y = 1 B. x = 1, y = 2 C. x = 2, y = 1 D. x = 4, y = 3

OpenStudy (welshfella):

5y >= 3x + 4 divide through by 5 y >= 0.6x + 0.8

OpenStudy (welshfella):

now plug in the values in the 4 options to see which one or ones fit

OpenStudy (kaylardz0405):

is it c

OpenStudy (welshfella):

x = 2 y = 1 y = 1 0.6(2) + 0.8 = 2 no - here y is < 0.6x + 0.8

OpenStudy (welshfella):

you need y to be greater or equal to 0.6x + 0.8

OpenStudy (kaylardz0405):

so then D

OpenStudy (welshfella):

i think you are guessing plug in the values and see if they fit try B

OpenStudy (welshfella):

for B y = 2 what does 0.6x + 0.8 equal ( here x = 1)

OpenStudy (kaylardz0405):

but isnt it 5*4 be one step if the answer was D

OpenStudy (kaylardz0405):

im kinda confused
