Which are the solutions of x2 = –7x – 8?

x = -3.5  ± √17/2

or

x =  -1.44, -5,56 to the nearest hundredth.

Step-by-step explanation:

x^2 = –7x – 8

x^2 + 7x + 8 = 0

Using the quadratic formula:

x = [-7 ± √(7^2 - 4*1*8)] / 2

x = -3.5  ± √17/2

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.

125 yards

step-by-step explanation:

i take 75 plus 50.
