4^x is an exponential function with base 4 and exponent x; its graph is entirely above the horizontal axis, and the curve representing 4^x continues to rise as x increases. Its y-intercept is (0,4^0), or (0,1).
Answer:
Step-by-step explanation:
you can factor this pretty straight forward
2x^2 +5x=12
2x^2 +5x-12=0
Use FOIL
(2x-3)(x-4)=0
then solve for each part separately, b/c if either side is zero the whole thing is zero
2x-3 = 0
2x = 3
x = 3/2
then
x-4=0
x = 4
In expanded form it is 4 + 0.7 + 0.02

Answer: the number of hpurs that Fran can watch this week is lesser than 12
Step-by-step explanation:
Let x represent the number of hours of television that Fran can watch in a week.
Fran is limited to watching television less than 12.6 hours per week. She has already watched 4.2 hours, and each show is 0.7 of an hour long. The inequality representing the situation is expressed as
0.7x + 4.2 < 12.6
0.7x + 4.2 < 12.6 - 4.2
0.7x < 8.4
x < 8.4/0.7
x < 12
