if x is negative, then the first number gets infinitely small
look at the second number, the first 2 is -2 which is wrong since it should be +2
3rd option is not because if x=-2, then y=1
answer is D

2nd: f(x)=60*1.15^x
3rd: no xint
6th: after 7.86 years value tripples
7th maybe: after 8 years value is 183.51, not exatly 184.00
4th attachment
nth score is
f(n)=57+4(n-1)
9th is
f(9)=57+4(9-1)
57+32=89
answer is C 89
5th
f(t)=23000(1.02)^t
t=time in years from 23000

Answer:
7 cubic yard
Step-by-step explanation:
Let the compost purchased be x cubic yard
And the topsoil purchased be y cubic yard
Hence
x+y=10 ----(A)
Also
Cost incurred in buying compost at a rate of $25 per cubic yards = 25x
Cost incurred in buying topsoil at a rate of $15 per cubic yards = 15y
Total cost incurred = 25x+15y=180
Diving whole equation by 5 we get
5x+3y=36 ----(B)
Multiply A by 3 and subtract it from B
5x+3y=36
- - -
3x+3y=30
_______
2x=6
x=3
Putting this value in A
x+y=10
3+y=10
y=10-3=7
Hence she purchased 7 cubic yards of topsoil.

OK. Hold on tight. Here we go.
Remember ... the "solution" is the number that 'g' must be
in order to make the equation a true statement.
The original equation: You said that -2 = g - 9
Now, let's add 9 to each side: 7 = g .
-2+9=g
g=7
Proof of answer if it's required on your test
-2= (7)-9
-2= 7-9
-2= -2
Plz put the equation down. Thx

so the equation is 90g*15%=13.5
