See below.
Step-by-step explanation:
1/2 = shrink by a factor of 1/2.
+7 = moved up 7 units.
X² - 8x - 20 factors to give option
B) (x - 10)(x + 2)
x² + 8x - 20 factors to give option
A) (x - 2)(x + 10)
x² - x - 20 factors to give option C) (x - 5)(x + 4)
and x² - 9x - 20 is option D) Prime.
I hope this helps!
An easy way is to work out their speed. Speed = distance/time.
First part: Speed = 330/5.5 = 60 mph
Finally, the second part: time = distance / speed
So time = 720/60 = 12 hours
The absolute value - or distance from zero, is fairly simple to find. Make your final answer positive to find it.
Always place it out of 9. For example, 0.333= 3/9, or if simplified, 1/3.
0.5555? this will be 5/9.
for the other way around, make it a repeating decimal, such as 4/9, make that 0.444
If it is 33/99, or even 333/999, the rule should be the same.
