Answer:
9p−18
Step-by-step explanation:
Expand by distributing terms
(−9×2 ) (−9×−p)
Simplify
−18−9×−p
Regroup terms
−18−(−9p)
Remove parentheses
9p−18
They would be examples of <span>equivalent fractions. i really hoped this helped.</span>
Answer:
Step-by-step explanation:
this is a radical equation:
when x=1 y=0
reflected about x
-sqrt(x)
right 1 unit
-sqrt(x-1)
it looks like y-int is about (0,1/3)
vertically compressed by a factor of 1/3
-(1/3)sqrt(x-1)
if you think the y-int is more (0,1/4), then
the function is vertically compressed by a factor of 1/4
-0.25sqrt(x-1)
Answer:
Anna is 43 years old and Jacob is 41 years old
Step-by-step explanation:
x + 1 + x + 3 = 92
2x + 4 = 92
2x = 92 - 4
2x = 84
x = 41
Answer:
Step-by-step explanation:
Let he speed of the boat on the lake is x.
<u>Considering the speed of the current it will take him:</u>
- 22.5/(x + 6) + 22.5/(x - 6) = 9
- 2.5 / (x + 6) + 2.5 / (x - 6) = 1
- 2.5(x - 6 + x + 6) = (x + 6)(x - 6)
- 2.5*2x = x² - 36
- x² - 5x - 36 = 0
- x = (5 ± √(5² + 4*36))/2 = (5 ± 13) / 2
- x = (5 + 13)/2 = 9 mph (negative root is discarded as the speed should be positive)
