Select the correct answer from each drop-down menu. A system of equations and its solution are given below.
System A
- y = 7
-3x + 9y = -39
Solution: (4,-3)
Complete the sentences to explain what steps were followed to obtain the system of equations below.
System B
x - y = 7
To get system B, the first equation in system A was replaced by the sum of that equation and
equation. The solution to system B the same as the solution to system A.

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

vertical asymptote .

horizontal asymptote .

step-by-step explanation:

given function is .

vertical asymptote is given by setting

denominator =0

when degree of numerator and denominator are same then divide first term of numerator by first term of denominator to get horizontal asymptote.
