f = (f1 f2) / (f1 + f2)
f(f1 + f2) = f1 f2
f f 1 + f f 2 = f1 f 2
f1 f2 - f f2 = f f1
f2 (f1 - f) = f f1
f2 = (f f1) / (f1 - f) <==== solution
Answer:
you have to find the area of the rectangle at the bottom and then find the area of the 2 long triangles and the 2 small triangles and add them together
Step-by-step explanation:
-x + 4 + 20x = 156
19x + 4 = 156
- 4. -4
19x = 152
19. 19
X = 8
Answer:
y = 2|x+3| -2
Step-by-step explanation:
1) slope = rise/run= 4/2 =2 - for the right line
2) y = 2|x| initial graph
3) It is moved 3 units left
y = 2|x+3|
4) It moved 2 units down
y = 2|x+3| -2
