Answer:
X=1/2
Step-by-step explanation:
-2x1/2=-1
-2x1=-2
-1+-2=-3
The value of x the function when x = -7.5 is 34.5
<h3>Functions and values</h3>
Functions are written in terms of variables
Given the expression –3.8x + 6, when the value of x is -7.5, hence;
f(x) = –3.8x + 6
f(-7.5) = -3.8(-7.5) + 6
f(-7.5) = 28.5 + 6
f(-7.5) = 34.5
Hence the value of x the function when x = -7.5 is 34.5

5a, because both are divided by 5 as the greatest common factor, and a to the first power (not a squared or cubed) is the greatest variable power they share :)
Answer:
Compare x^2 +y^2-8x-6y=75 with the general circle equation x^2+y^2 -2ax-2by+c=0
-2a =-8 And -2b=-6
a=4 b=3
c=-75
To find the radius use the equation
r^2=a^2+b^2-c
r^2=4^2+ 3^2-(-75)
r^2=25+75=100
r=10(radius is always positive)
Hence the center is (4,3) and radius 10
