Infinitely many because if you subtract 7x from both sides, you get 4 = 4, which is true at all times no matter what x is.
I believe it's A. <span>Eva would have been better off selecting the 20-year term policy.
Unde current circumtances, 10-year term policy wouldn't guarantee thesafety of the kids because even after the policy ends, Eva's kids still haven't entered the age where they could find their own income (they would be 12, 13, and 15).
If Eva decided to add another 10 year despite the extra charge, The kids will be covered until they enter the productive age.</span>
R= 5
You divide -7 by both sides to 1. Cancel out the -7 2. To simplify the -35. So simplified -35/-7=5
Answer: -7/3≤t≤5/3
Step-by-step explanation:
|2t + 2/3|≤4
2t + 2/3≤4
(2t + 2/3≤4)*3
6t+2≤12
6t≤10
t≤10/6
<u>t≤5/3</u>
2t + 2/3>=-4
(2t + 2/3>=-4)*3
6t + 2>=-12
6t>=-14
t>=-14/6
<u>t>=-7/3</u>
-7/3≤t≤5/3
Use TrianCal to draw a triangle with phi as Great Piramid (minimum perimeter given 2 equal heights) = maximun stability.
NOTE: Phi=(1+√5)/2≈1.62 and acos(1/Phi)≈51.83º
