Use the substitution method to solve the system of equations
yarga [219]

Answer:

C. (3,2)

Step-by-step explanation:

to begin the substitution method, we can begin by substituting the answer choice value into the given system or equations to determine if the values make the equation true.

the first choice is (2,1)

3(2) + 2(1) = 13

6 + 2 is not equal to 13. Therefore this answer choice is incorrect.

second choice (1,2)

3(1) + 2(2) = 13

3 + 4 is not equal to 13. This answer is also incorrect.

third choice (3,2)

3(3) + 2(2)

9 + 4 = 13 is true!

we can also substitute these x and y values for the equation underneath:

y = x - 1

2 = 3 - 1

2 = 2 is true! Therefore, C. (3,2) is correct!

\mathrm{Compute\:the\:ratios\:of\:all\:the\:adjacent\:terms}:\:r=\frac{a_{n+1}}{a_n}

\frac{36}{6}=6,\:\quad \frac{216}{36}=6,\:\quad \frac{1296}{216}=6,\:\quad \frac{7776}{1296}=6

\mathrm{The\:ratio\:of\:all\:the\:adjacent\:terms\:is\:the\:same\:and\:equal\:to} \ \textgreater \  r = 6

There is a bit more to the answer but it just explains a bit more that this question does not ask for.

Hope this helps!
