Answer:
The number is 2
Step-by-step explanation:
Twice a number (z) = 2*z = 2z
Twice a number (z) added to 21 = 2z + 21
9 times the number added to 7 = 9z + 7
9z + 7 = 2z + 21
Subtract 2z form both sides
9z - 2z + 7 = 21
7z + 7 = 21
Subtract 7 from both sides
7z = 21 - 7
7z = 14
Divide both sides by 7
z = 14/7
z = 2

Answer:print out starter sheets
Step-by-step explanation:
Plug in the given values and you'll see its option 2.
x=0 , f(x) = 0^2 + 1 = 1
x = 1 , f(x) = 1^2 + 1 = 2
x = 2, f(x) = 2^2 + 1 = 5
2,3,7,8=
1)3*7=21
2)2*8+7=32
3)7*3+8=29
4)7*3+2=23
5)7*8 divided by 2=28
6)8*3=24
7)2*3*8=48
