Answer:
x = -4
Step-by-step explanation:
Isolate the x by substracting 2.3x from both sides, then subtract 21.6 from both sides.
After that, you will have 1.15x = -4.6. Divide both sides by 1.15 to get x = -4.
after doing the math i got 2/93
Answer:
Option D is correct .i.e., All Real Number
Step-by-step explanation:
Given Logarithmic Function,
First we simply the function,
F(x) = x × log(0.5)
F(x) = -0.30103x (by putting value of log(0.5) )
Its clear range of F(x) completely depends on value of x .i.e, Domain of Function
Domain of log function is real Numbers
⇒ Ranges is also the Real Numbers
Therefore, Option D is correct .i.e., All Real Number

Explanation:
a perpendicular bisector, bisects a line segment at
right angles
to obtain the equation we require slope and a point on it
find the midpoint and slope of the given points
