Answer: 3
Step-by-step explanation:
(-3/4)/(-2/8)=(-3/4)(-8/2)=(-3/4)(-4)=3
Answer:
The range of F(x) = logbx is the set of all positive real numbers is TRUE
Step-by-step explanation:
Given:
A function which logarithmic i.e F(x)=logbX=logx/logb with base 10
To Find;
Range belongs to All set are positive real numbers.
Solution:
The domain is function for which all set of inputs are defined and range for function is that set of all output that functions takes.
So Simple logarithmic function y=logbX is

So The functions has domain of all real values and range set of all real number.
In general the function F(x) = logbx where X>0 and b≠1 is continuous and one to one function.
logarithmic function is not defined for negative numbers or for zero.
And Also function approaches y-axis as x-tends to infinity but never touches the it.
Hence the Given statement is true
Answer:
Step-by-step explanation:
Check the attached diagram... since they are parallel lines, those angles should be equal. now as per the theorem of opposite angles, (3x + 10)° should be equal to 70° .
(3x + 10)° = 70°
3x = 60°
x = 20
Answer:
x=3
Step-by-step explanation:
cross multiply
12.5*2=30
10*x=10x
10x=30
/10
x=3
