Independent means the equations are differnt
dependent means that they have infinite solutions aka they are the same line
consistiant means it has at leas 1 soltuion
inconsistent means tat they do not intersect at all
solve each
1. 6x-1.5=-6x+1.5
12x=3
x=0.25
y=6(0.25)-1.5
y=1.5-1.5
y=0
(1/4,0)
consistant and independent
2.
-2x-6y=12
<u>2x+6y=3 +</u>
0=15
false
independent and inconsistint
3.
if we muliply the first equation by 3, we get that they are the same equation meaning
dependent and consistent

Answer:0.019 i think
Step-by-step explanation:
you would use the variability formula which is the squareroot p(1-p)/n
Answer: 384 in
Step-by-step explanation: 12 in*10 in=384 in
5.4 because you set up a proportion 7/19=2/x, 19*2=38, 38/7=5.4285, rounded you get 5.4
Answer:
any angle under 90 degrees is acute. A right angle is 90 degrees always, and obtuse angles are always above 90 degrees. Straight angles are always 180 degrees. A reflex angle is more than 180 degrees but less than 360 degrees. Hope this helps.
