Answer:
Because a prism travels at the speed of light.
Answer:
a=2
b=10.5
c=4
d=17.5
Step-by-step explanation:
so 3.5 miles per hour and the columns are miles and then hours
so an equation can be 3.5 (mi/hr) * t (time) = distance
so for a): 3.5*t=7
t=2
b) 3.5*3=distance
distance is 10.5
c) 3.5*t=14
t=4
d) 3.5*5=d
d= 17.5
Answer:
B) -|x + 3| = 3
D) |x + 3| + 6 = 3
Step-by-step explanation:
A) |x + 3| = 3
B) -|x + 3| = 3
Divide by -1
|x + 3| = -3
Absolute values are 0 or positive so this cannot have a solution
C) |x + 3| + 3 = 3
Subtract 3 from each side
|x + 3| + 3-3 = 3-3
|x + 3| = 0
D) |x + 3| + 6 = 3
Subtract 6 from each side
|x + 3| = -3
Absolute values are 0 or positive so this cannot have a solution
