None of them will get into a negative number. When you have like "2x" is the number twice, right? Some number has to be negative
Whats the rest of the question?
Answer:
yes
Step-by-step explanation:
A rational number can be expressed in the form
← where a, b are integers
Given
← multiply numerator/ denominator by 10
=
= 5 =
← a rational number
Answer:
x>0
Step-by-step explanation:
We want to solve for x in the inequality:
4^x > 1
ln(4^x)=xln(4) > ln(1)=0
x > 0/ln(4) =0
x>0
So for any value of x greater than 0, you will have 4^x be greater than 1.
Answer:
-6
Step-by-step explanation:
The average rate of a function f(x) on the interval from x=a to x=b is
.
So in the problem you have from
to
.
The average rate of the function from x=2 to x=4 is
.
Now we need to find f(4) and f(2).
f(4) means what is the y-coordinate that corresponds to x=4 on the curve.
f(4)=-15 since the ordered pair at x=4 is (4,-15).
f(2) means what is the y-coordinate that corresponds to x=2 on the curve.
f(2)=-3 since the ordered pair at x=2 is (2,-3).
So let's plug in those values:
.
Now we just simplify:
