Answer:
rational
Step-by-step explanation:
Any rational number can be expressed in the form
← where a and b are integers
Given
= - 2 or + 2
Since - 2 = and 2 = ← both in rational form, then
is rational
Answer:
It's D
Step-by-step explanation:
2t - 30() = 20
2t - () = 20
2t - = 20
2t - 6 = 20
2t - 6 + 6 = 20 +6
2t = 26
=
t = 13

the derivative of a constant is always zero
Remember you can do anything to an equaiton as long asyou do it to both sides
4v+18≥6v+10
minus 4v both sides
4v-4v+18≥6v-4v+10
0+18≥2v+10
18≥2v+10
minus 10 both sides
18-10≥2v+10-10
8≥2v+0
8≥2v
divide both sides by 2
8/2=(2v)/2
4≥(2/2)v
4≥1v
4≥v
v≤4
