-2

Step-by-step explanation:

(-1/2)³ ÷ (1/4)²

(-1/8) ÷ 1/16

-1/8 × 16/1

-2

2

Step-by-step explanation:

| (-½)³ ÷ (¼)² | = | (-1/8) ÷ (1/16)|

= | (-1/8) × (16/1)|

= | -2 |

= 2

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.

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
