Answer:
10s²-6s+9
Step-by-step explanation:
C = -3 + 5s²
B = -2s + 5
2(-3 + 5s²) = -6 + 10s²
3(-2s + 5) = -6s + 15
10s² - 6s + 9
Answer:
The dog will catch the cat at 33.33 sec
Step-by-step explanation:
Let
x------> distance the cat runs before being caught by the dog,
Remember that
The speed is equal to divide the distance by the time
v=d/t
solve for t
t=d/v
so
equate the time
x/24=(200+x)/30
30x=24(200+x)
30x=4,800+24x
30x-24x=4,800
x=4,800/6=800 m
t=d/v=800/24=33.33 sec
or
t=(800+200)/30=1,000/30=33.33 sec
Since -1 is less than or equal to -1 you input it into the first equation.
-3•(-1) -4
3-4
-1
the answer is -1 good luck
-2/3 ÷ 1/3
=(-2 × 3) / (1 × 3)
= -6/3
= -2/1
