5x+6y=18
5x=18-6y
x=(18-6y)/5
Use that in the other equation
18(18-6y)/5 - 15y = 36
64.8-21.6y - 15y = 36
28.8=36.6y
.7868=y
Now put that number in for y on the first equation
5x+6(.78) = 18
5x + 4.68 = 18
5x = 13.32
x = 2.66
and y = .78
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
The triangle is an isosceles triangle so that means the base angles must be congruent.
The sum of the interior angles of a triangle add up to 180 degrees.
Subtract 52 degrees from 180 degrees.
180 - 52 = 128
Divide 128 degrees by 2.
128/2 = 64
m∠X = 64°
You multiply six by six and then get 36 and divide 36 to 4 and you would get 9 so put 9 in the 6 6's that you got.
