Step-by-step explanation:
Answer:
(21, 28)
Step-by-step explanation:
Multiply coordinates by 7.
Answer:
1st . The shaded region of the graph ....
2nd. The graph line is solid.
4th. The ordered pair (2 ; 5) is part of the solution set.
Step-by-step explanation:
. Because y is <u>greater</u> or equal than the line, everything above the line is part of the solution.
. Since y is greater or<u> equal</u>, the line is solid. If y was only greater the line would have been dotted.
. The pair (2 ; 5) represent the x = 2 w/ y = 5, and reading the graph you can see the at this point the lines passes through it.
2(b+3) = 2
2b + 6 = 2 ( -6 )
2b = -4 ( / 2)
b = -2
