Answer:
-5.6
Step-by-step explanation:
g(x)=2x-1
g(-2.3)=2(-2.3)-1=-4.6-1=-5.6
A. x * .85 = y or .85x = y
B. x - 2 = y
C. (x - 2) * .85 = y or .85(x - 2) = y
D. .85x -2 = y or (x * .85) - 2 = y
E. The discount then the coupon
The area of a circle is given by
whereas the circumference is given by
If we want these two values to be (numerically) the same we have to set and solve for the radius:
So, one (trivial) solution is . A circle with radius 0 is just a point, and so both area and circumference are zero.
The other solution is . In fact, you have
500 meters per day * 7 days per week = 3500 meters per week.
3500 meters per week * 1/1000 kilometers per meter = 3.5 kilometers per week.
