Which expressions have products of -0.64? if they do not have a product of -0.64, explain a way to make them have that product.
a.(0.)
b.1.6(-4)
c.0.64(-1)
d.(1..5)
.16)

A, C, and D are correct

Step-by-step explanation:

A. (0.32)(-2)

(0.32)(-2) = -0.64

Correct.

B. 1.6(-4)

1.6(-4) = -6.4

Wrong.

Divide by 10.

C. 0.64(-1)

0.64(-1) = -0.64

Correct.

D. (1.28)(-0.5)

(1.28)(-0.5) = 0.64

Correct.

E. (-4)(-0.16)

(-4)(-0.16) = 0.64

Wrong.

Multiply by -1.

(0.64)(-1)= -0.64

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.
