Answer:
12a+200=644
Step-by-step explanation:
take the equation and cancel out 200 and do it to both sides
12a+200=644
-200. -200
------------------------
12a=444
then we need to get the variable alone so divide by 12.
12a = 444
---- ----
12. 12
a=37
444 divided by 12 will equal 37
Seven hundred seventy thousand seventy

If <em>x</em> = -1, you have
2(-1) + 3 cos(-1) + <em>e</em> ⁻¹ ≈ -0.0112136 < 0
and if <em>x</em> = 0, you have
2(0) + 3 cos(0) + <em>e</em> ⁰ = 4 > 0
The function <em>f(x)</em> = 2<em>x</em> + 3 cos(<em>x</em>) + <em>eˣ</em> is continuous over the real numbers, so the intermediate value theorem applies, and it says that there is some -1 < <em>c</em> < 0 such that <em>f(c)</em> = 0.
Your work is correct! Sally can only half 15 boxes per drive. She has 50 boxes. So, it takes her 3 drives to get 45 boxes to shops. Because she has to deliver 5 more boxes, Sally has to take one more trip. Sally has to take 4 total trips.
