Answer:
2 and 4 are correct
Step-by-step explanation:
1 is incorrect because 4/5 being bigger than 7/10
3 is incorrect because 2/3 is more than 5/9
5x + 2y=50
or
5x + 2y<=50 (less than or equal to)
then
x + 2y=30
or
x + 2y<=30(less than or equal to)
An infinite number of solutions means a coincident line...it is the same line 3y = 2x - 9...divide by 3 y = 2/3x - 3...hmm...same line as answer choice b....they are coincident lines and have infinite solutions
Replace a with 4 and b with -12 3(4) + -12/4 + 4(4) = 16+-12/4+4*4 = 29
You can find the area of a hemisphere by using the following equation V = (2/3) (pi)*r^3 so V = (2/3) (pi)*1.6^3 Which comes out as 8.5786423394 or 8.6
