Sumiko must study at 10 hours each week. she has studied 4 hours already. how many hours must she study ?

Since she had already studied 10 hours, and she has to study 4 more. It is 10 hours minus 4 hours she already studied. So the expression is 10-4= ___ and the answer would be 6 more hours that she needs to study.If this is right could you possibly give me brainliest? Hope this helped.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
