2. 1. 3. 4.
Step-by-step explanation:
hope this help >.<
3x + 4y = 18......(2,3)
3(2) + 4(3) = 18
6 + 12 = 18
18 = 18...correct
2x - 2y = 2....(2,3)
2(2) - 2(3) = 2
4 - 6 = 2
-2 = 2...incorrect
when (2,3) is subbed into equation 1, it is true
when (2,3) is subbed into the second equation, it is false
the ordered pair (2,3) is not a solution to the system of linear equations
Answer: 1. B 10(15 12 + 8) = 350
2. C
Step-by-step explanation:
anaalyze the problem
first term: -1
common difference: +9 (8-(-1) is 9)
so, an=-1+9n-9
answer is an=9n-10, with n bigger or equal to one
sixth term,plug in 9(6)-10=54-10=44
tenth term, plug in 9(10)-10=90-10=80
Po = 95
r = 15% = 0.15
t = 2023 - 2015 = 8
P = Po * e^(rt)
P = 95*e^(0.15*8)
P = 95*3.32
P = 315.41
