Answer:
1 is true , 2 is false
Step-by-step explanation:
for equation 2
-2x<8
-2x=8
then we divide both side by coefficient of x which is -2
-2x/-2=8/-2
we will be left with
x= 8/-2
x=-4 which shows that x<-4 and it differs from the second inequality
6x + 8y = 24
6(4) + 8(0) = 24
No it is not a linear equation because a linear equation has to be y=?x with nothing else on the end
Answer:
<u>v = √(LT/m)</u>
Step-by-step explanation:
Given :
Multiply both sides with L :
- T × L = mv²/L x L
- LT = mv²
Divide both sides by m :
- LT × 1/m = mv² × 1/m
- LT/m = v²
Take the square root on each side :
- √v² = √(LT/m)
- <u>v = √(LT/m)</u>
