Answer is A 6x - 21 as the -3 makes the -2x positive and 7 into a negative 21
Quadratic is the y=2x^2
that is the parabola one
when will the exponential one be higher than the parabola?
that is, hmm, find the intersection points
we can see that x=1 is an intersection point
we see that it is between the intersection points
if we use our calculator
intsersect at x=-0.578621 and 1
so it is the one from -0.5 to 1
that is the 3rd option
-0.5≤x<1
Answer:
did you answer this already
Answer:
Concept: Numerical Understanding
- First off its eight point five minus blank equals seven point fifteen
- The missing variable is a number that sums to 7.15
- Instinctively you could rearrange or see the value missing is 1.35
Scientific notation has to be greater then 1 and less then 10 and a decimal is less then one so we have to bring that decimal over 6 places to the right to get 6 x 10^-6
Answer: 6 x 10^-6
