Answer:
first option
Step-by-step explanation:
Given
| x + 4 | = 2
The absolute value function always produces a positive value but the expression inside can be positive or negative, thus
x + 4 = 2 ( subtract 4 from both sides )
x = - 2
OR
- (x + 4) = 2, distribute left side
- x - 4 = 2 ( add 4 to both sides )
- x = 6 ( multiply both sides by - 1 )
x = - 6
Thus solutions are x = - 2, x = - 6
These are represented on the graph by solid blue circles at x = - 2, x = - 6
The first option represents the solution
Step-by-step explanation:
|-(-4)| is modulus of -(-4)
|-(-4)| =4
Answer:
when the survey was initially conducted the average sales of smartphones was 1.7 million units
Step-by-step explanation:
The average annual sales of smartphones is given by function
Exponential growth function is given by
Where a= initial value
b = growth factor , b= 1+r where 'r' is the growth rate
x is the time period
Now we compare f(x) with P(n)
the value of a= 1.7 that is the initial value.
So we can say, when the survey was initially conducted the average sales of smartphones was 1.7 million units
Is there more because with out it we can’t understand what it means
Answer:
π = C / d
Step-by-step explanation:
The circumference of a circle is given by the general formula;
C = 2 * π * r .... or C = π d (r = radius, d = diameter)
We can easily modify the second formula to isolate π in order to express the circumference in relation to the diameter:
π = C / d
To obtain π, you need to divide the circumference by the diameter.
We're used to think about the circumference in terms of radius... but since we deal with 2 * r * π and that 2 * r = d... it's also convenient to use the diameter.
