Answer:
x>=5/6
Step-by-step explanation:
She's practiced 2 1/3 hours already. Therefore, she has 1 2/3 hours left to practice. Let x be the minimum number of hours she needs to practice on each of the remaining two days.
Splitting up the remaining hours into two days, we get (5/3) divided by 2, which is 5/6 hours per day.
x is greater than or equal to 5/6 hours per day.
Whatever your choices are, just substitute the x and y values to the equations. If they satisfy the inequality, then they are the solutions. For example, point (7, 1) satisfies the inequalities.
y > -2x
1 > -2(7)
1 > -14 (true)
<span>3y < x – 2
3(1) < 7 - 2
3 < 5 (true)
I hope I was able to help you. Have a good day.</span>
Answer:
=3x^4+3x^3−x^2−3x+15
Step-by-step explanation:
Answer: 4π/15, 4π/3 and 28π/15 (in radians)
Step-by-step explanation:
Recall that 
= 
This implies that
Therefore the values of 
between 0 and 2π are 48, 240 and 336. (All in degrees)
48 degrees= 4π/15 rad
240 degrees =4π/3 rad
336 degrees = 28π/15 rad
