Answer:
The systems of equation are identical and such there are infinitely many solutions. For the first part the correct answer is B. For the second part, the correct answer is A
Step-by-step explanation:
If we multiply the first equation by 4 the result is the second equation and thus the systems of equations are scalar multiples of each other. The solution to such a system is found by expressing one variable in terms of the other hence choice B.
Since the systems are scalar multiples of each other, if we graph them they would simply coincide since they are identical, that is they have same slope and y-intercept.
Answer:
Step-by-step explanation:
5.7 + 2(w+1) = 2w + 9
5.7 + 2w + 2 = 2w + 9
7.7 = 9, which is impossible, so there is no solution.

-8(4+9r) = 7(-2-11r)
-32-72r = -14-77r
5r = 18
r = 3.6
