Well, i'm just going to take a stab at this:

The answer out of:
> It is (18,9) ,
> It is (9, 18)
I believe both are correct as those are both plausible coordinates (although I may be wrong)

Line R: 2x + 2y = 18 (x + y = 9)
Line M: x + y = 9
There are infinite many solutions as they are the same line.

Expression A Expression B Expression C (−5)(−0.4)(1.8) (-45)(-19)(-112) −1(5+17) Expression D Expression E Expression F (−5)(−0.
kramer

Answer:

Expressions A, E, and F

Step-by-step explanation:

In general, when negative integers are multiplied; if the negative integers are even, then the product would be positive. But if the negative integers are odd, then the product would be negative.

Thus,

A. (−5)(−0.4)(1.8) = (2.0)(1.8)

                           = 3.6

B. (-45)(-19)(-112) = (855)(-112)

                           = -95760

C. −1(5+17) = -1(22)

                 = -22

D. (−5)(−0.4)(1.8)(−3.25) = (2.0)(-5.85)

                                      = -11.7

E. (-49)(-34)(-12)(-12) = (1666)(144)

                                = 239904

F. −1(3.5−7) = -1(-3.5)

                  = 3.5

Thus expressions A, E and F have positive products.

Enter the value of y that makes the given equatlon true.<br> 15y +3= 6
Lunna [17]

Answer:

y = 1/5 or y = 0.2

Step-by-step explanation:

15y +3= 6\\15y+3-3=6-3\leftarrow \text {Subtraction Property of Equality} \\15y=3\\\\\frac{15y}{15} =\frac{3}{15} \leftarrow \text {Divsion Property of Equality}\\

y=\frac{3}{15}\\\frac{3/3}{15/3} = \frac{1}{5} \leftarrow \text {Simplifying the Answer}\\\boxed{y=\frac{1}{5}}
