Question

X+2y is greater than or equal to 10. Which of the following ordered pairs are solutions to the system

Answer 1

Answer:

(4,4), (2,8)  (4,8)  and all points in the shaded region as attached below

Step-by-step explanation:

This question is on solutions for inequalities equations

Give the equation as;

x+2y ≥ 10.......................................rewrite the equation for graphing purposes

x+ 2y = 10.............................................compose a table for values of x with corresponding values of y

x  -2    0   2  

y   6    5    4

Plot and shade the wanted region as show in the attached graph

For example point (4,4)  or point (2,6) will satisfy the  inequality  x+2y ≥ 10 as;

(4,4)........ x+2y ≥ 10------4+2(4)  ≥ 10

20 ≥ 10 ,,,,,,,,,,,,,,,,,,which is okay
