Answer:
8
Step-by-step explanation:
If f and g are inverse functions , they undo each other
f(g(8))= 8 when f and g are inverses
Answer:
option c
Step-by-step explanation:
-3x+8-5x=21-8x
-3x-5x+8=21-8x
-8x+8=21-8x
if -8x crosses the equals
8=21
x has infinitely many solutions
I'm pretty sure that the answer to the fudge cakes is 8 friends
So to find a percent of increase you have to put the current number minus previous number(in this case 20-16) over the previous number(16 in this case) and multiply by 100.
So we have 20-16/16 multiplied by 100.
Since 4/16= 0.25,multiplying It by 100 gives you 25.
So the answer is 25%
Answer:
(a) isosceles
(b), (c) scalene
Step-by-step explanation:
The lengths of the sides can be found from the distance formula:
d = √((x2 -x1)^2 +(y2 -y1)^2)
Here, there are 9 lengths to be computed, so it is useful to let a spreadsheet or graphing calculator do it.
We find triangle (a) has two sides the same length, so it is isosceles.
The other two triangles have three different side lengths, so they are scalene.
