Answer:
x=7
Step-by-step explanation:
add 7 to both sides
9x=5x+28
subtract 5x from both sides
4x=28
divide both sides by 4
x=7
In order to factor a polynomial, you have to find its roots
So that you can factor it as
So, in this case, we're looking for the solutions of
So, the polynomial can be written as
Answer:
b
Step-by-step explanation:
5 days a week
9 hours a day
there are 52 weeks which means he works 260 days and 2340 hours a year
divide 29000 by 2340 and u get 12.4 per hour
Step-by-step explanation:
K is an upper bound for│f"(x)│on the interval [0, 1], so x ≤ 1.
Sine and cosine have maximums of 1, so an upper bound of │f"(x)│is:
│f"(x)│≤ (76 · 1 + 152 · 1 · 1)
│f"(x)│≤ 228
