Hello,
f'(x) = sin(x) - 65 → f(x) = -cos(x) - 65x
Sugar: x pounds
flour: 2x + 5 pounds
2x + 3(2x + 5) = 40
2x + 6x + 15 = 40
8x = 25
x = 3.125
-> a sack of flour is 3.125 + 5 = 8.125 pounds
I hope it‘s coorect
About three years. Hope it helps!
2n+14=14+2n so this one as an infinite number of solutions. The second one 1-x=-x-6 so you add x on both sides which results in it having no solutions.
Yes in order for them to be symmetrical they both have to be Symmetrical or the same
