Answer:
<em>n = 6 </em>
Step-by-step explanation:
2.3 ×
= (1 × 10³)(2.3 ×
)
(1 × 10³)(2.3 ×
) = (1)(2.3) × (10³)(
) = 2.3 ×
2.3 ×
= 2.3 ×
⇒ 3 + n = 9 ⇒ <em>n = 6</em>
6.375 is greater than 6.333
Answer:
x > - 4
Step-by-step explanation:
Given
7(x + 4) > 0 ← distribute left side
7x + 28 > 0 ( subtract 28 from both sides )
7x > - 28 ( divide both sides by 7 )
x > - 4
Answer:
The domain of the function f(x) is:

The range of the function f(x) is:

Step-by-step explanation:
Given the function

Determining the domain:
We know that the domain of the function is the set of input or arguments for which the function is real and defined.
In other words,
- Domain refers to all the possible sets of input values on the x-axis.
It is clear that the function has undefined points nor domain constraints.
Thus, the domain of the function f(x) is:

Determining the range:
We also know that range is the set of values of the dependent variable for which a function is defined.
In other words,
- Range refers to all the possible sets of output values on the y-axis.
We know that the range of an Absolute function is of the form


so
Thus, the range of the function f(x) is:

Answer:
= 5u
Step-by-step explanation:
You combine like terms
( 2u+ 8u = 10u )
( -5u + 10 u =5u)
