Use the geometric sequence formula to solve for rate:
an=a1r^(n-1)
6.75=4.5r^(2-1)
6.75=4.5r
6.75/4.5=r
r= 1.5
and if you want to make sure just multiply each number by 1.5 and see if it gets you the next number
4.5 4.5×1.5=6.75 (holds true)
6.75 6.75×1.5=10.125 (holds true)
10.125 10.125×1.5=15.1875 (holds true)
15.1875
1.5 is the multiplicatice rate hope that helps :)

Answer:
x = 6 y = -9
Step-by-step explanation:
8x +2y = 30
-7x + 2y =24
x= 6
8(6)
48 + 2y =30
-48. -48
2y = -18
÷2. ÷2
y = -9
