Answer:
Step-by-step explanation:
A exponential function is represented by
where a is the vertical stretch and b is the base and x is the nth
power of x
Since the first number corresponds with zero, that means our y intercept is the first number.
This means when x=0 , y=5 so let find the value of 5.
b to the 0th power equal 1 so
Our equation is for now
Now let plug in 1,30
Divide 5 by both sides
Anything to the 1st power is itself so b equal 6.
So our equation is
Answer:

Answer:
2.63
Step-by-step explanation:
29/11=2.63
Answer:
Multiplication -> Division
Squaring -> Square rooting
Cubing -> Taking the cube root
Addition -> Subtraction
Alternative:
* -> /
^2 -> √
+ -> -
^3 -> 3√
Basically, an inverse is a mathematical manipulation where one operation undoes the action of the other.
<span>a. n/4 ≤ -1
Multiply both sides by 4 => n ≤ - 4, which is all the real numbers less or equal than - 4.
That in the real number line is all the numbers to the left of - 4 (including -4)
The matching graph is the B.
b. -10n ≥ -100
Divide both sides by - 10 => n ≤ 10
That is all the real numbers less or equal than 10.
In the real number line it is all the numbers to the left of 10, including 10.
So, the matching graph is the A.
c. 5x ≥ 20
Divide both sides by 5 => x ≥ 4
That is all the real numbers greater or equal to 4.
In the real number line it is all the numbers to the right of 4, including 4.
The matching graph is C.</span>
