Answer:
-20
Step-by-step explanation:
18. 1 3/4, 7/5, 1 3/10, 11/20, 1/4
19. 3 1/3, 2 1/5, 9/5, 9/10, 2/15
Extraneous Solutions maybe?
2/5=w-3/2
remember that to solve we want to isolate 1 w one side by itself
also remember that we can do anything to an equation as long as we do it to both sides (except divide by zero)
2/5=w-3/2
so we add 3/2 to both sides to get rid of the 3/2
2/5+3/2=w+3/2-3/2
2/5+3/2=w+0
2/5+3/2=w
make the bottom numbers the same
the number is 10
2/5 times 2/2=4/10
3/2 times 5/5=15/10
4/10+15/10=w
4/10+15/10=(4+15)/10=(19)/10
w=19/10
so the steps are:
1. add 3/2 to both sides
2. make the denomenators of 2/5 and 3/2 the same so we can add them
Answer:
f(x + 1) = x² - x
Step-by-step explanation:
f(x) = x² - 3x + 2 when f(x + 1)
f(x + 1) = (x + 1)² - 3(x + 1) + 2
f(x + 1) = (x² + 2x + 1) + (-3x - 3) + 2
f(x + 1) = x² - x + 0
f(x + 1) = x² - x
Best of Luck!
