Answer:
-4 1/2, -2 3/8, 1.35, 5.6
It will cost 3.5*1.8 which 3 * 1.8 is 5.4 and then add .5 of 1.8 which is 0.9 and 5.4+.9 is 6.3 dollars.
Remember that e is equals to 2.717 something and to find the value of the infinities, you must consider there signs. So the e^infinity approaches to infinity while the e^-infinity approaches to zero. I hope you are satisfied with my answer and feel free to ask for more
Answer:
-1/3
Step-by-step explanation:
3x-2(4x+1)=10x+3
3x-8x-2=10x+3
-5x-2=10x+3
-5x-10x-2=3
-15x-2=3
-15x=3+2
-15x=5
x=5/-15
simplify
x=-1/3
