12. The temperature of a small pudding was -4°C when taken out of the freezer. The pudding was immediately warmed in a saucepan, and after 8 minutes its temperature was 16°C. (a) By how much had the temperature risen during the 8 minutes? (b) Given that the temperature of the pudding increased at a constant rate, calculate (i) the number of minutes it had warmed when its temperature reached 0°C, (ii) its temperature when it had been warmed for a total of 24 minutes.​

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.
