Answer:
2.28X10^1
Step-by-step explanation:
I will refer ^a as exponent of a.
7.3X10^6 ÷ 3.2X10^6=7300000÷3200000
=2.28125
=2.28X10^1
0.98 because you multiply and then make shift the decimal
Answer:
(a) f(7) = 23
(b) x = 13/3
Step-by-step explanation:
Step 1: Define
f(x) = 3x + 2
(a) f(7) is x = 7
(b) f(x) = 15
Step 2: Substitute and Evaluate
(a) f(7) = 3(7) + 2
f(7) = 21 + 2
f(7) = 23
(b) 15 = 3x + 2
13 = 3x
x = 13/3
