Write the quadratic equation whose roots are −1 and −6, and whose leading coefficient is 5.

5(x+1)(x+6)

Step-by-step explanation:

Since the Since -1 is a root, x - (-1) = x + 1 is a factor

Similarly, x + 6 is also a factor

So,  5(x+1)(x+6) = 0 is the quadratic equation.

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.
