Answer:
6x^2+4xy
Step-by-step explanation:
Hope that helps you out!
What I did was move the points 2 time to the right (or multiply by 100) and divided by 2 twice to get 41/550. For a decimal, I used a calculator and approximated the answer to 3 significant figures (just to be safe).
Substitute the given number in your formula and solve for the remaining variable.
.. 300 = 100e^(0.7t)
.. 3 = e^(0.7t) . . . . . . . . . divide by 100
.. ln(3) = 0.7t . . . . . . . . . .take the natural logarithm
.. ln(3)/0.7 = t . . . . . . . . . divide by the coefficient of the variable
.. 1.6 = t
Selection B is appropriate.
Answer:
C
Step-by-step explanation:
five times a number = 5x
plus 7 = 5x+7
is 3 less 10 times the same number = 10x - 3
