Answer:
4
Step-by-step explanation:
2x - 1 = 7
2x = 8
x = 4
using the rule of exponents
⇔
f(- 5) = = =
-0.05
Given the expression :
0.1×( – 0.9+ – 0.2÷ – 0.5)
Evaluating the bracket :
0.1 * (-0.9 - 0.2 ÷ - 0.5)
Solving the division first
-0.2 ÷ - 0.5 = 0.4
Now we have ;
0.1 * (-0.9 + 0.4)
0.1 * - 0.5
= - 0.05
