Answer:
False
Step-by-step explanation:
Rewrite equation:
f(x)=1+x
Substitute X for 1:
f(1)=1+1
Combine like terms:
f(1)=2
the equation equals 2 not 0 so it is false
8th grade = 3x = 3(47) = 141 band members.
7th + 8th = 188
7th = x
8th = 3x
x + 3x = 188 ; x = 47 ; 47 + 3(47) = 47 + 141 = 188
4x = 188
4x / 4 = 188 / 4
x = 47 --> 7th grade
8th grade = 3x = 3(47) = 141
To check:
x + 3x = 188 ; x = 47 ;
47 + 3(47) = 188
47 + 141 = 188
188 = 188
