Two lines, r and m, are represented by the following equations:

line r: 2x + 2y = 18
line m: x + y = 9

which statement is true about the solution to the set of equations? (4 points)

select one:
a. it is (18, 9).
b. it is (9, 18).
c. there are infinitely many solutions.
d. there is no solution

c

Step-by-step explanation:

Note that line M is the same equation as line R and hence there are infinitely many solutions.

Line R : 2x + 2y = 18

Line M : x + y = 9 ⇒ 2x + 2y = 18

step-by-step explanation:

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
