What is the value of -216x – y when x =-3 and y = 4?
O 44
0-28
O 28
O 44

644

Step-by-step explanation:

We know that:

x = -3

y = 4

We can find the value of our expression by substituting x and y with the values given above. For example, instead of y, we'll put 4:

Since -216 * -3 is equal to 648:

644

you can not drow on this

step-by-step explanation:

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.
