Keep in mind following properties of multiplication of two integers

1. (-a) × (-b)= + ab

2. (-a) × (b)= - (ab)

3. a × (-b)= - (ab)

(a.)

So, Product of a Positive number and Negative number will be Negative.

Option A: -2

 Option D: -10

(b)

Product of two negative numbers and a positive number

  =As product of Two negative will be positive and positive multiplied by positive will be Positive.

lozanna [386]

Answer:

The circle's diameter is 4\ yd

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=\pi D

where

D is the diameter of the circle

In this problem we have

C=12.56\ yd

\pi=3.14

substitute the values and solve for D

12.56=(3.14)D

What is the point of intersection when the system of equations below is graphed on the coordinate plane?
Artist 52 [7]

Answer:

This system of equations has infinite points of intersection

Step-by-step explanation:

* To know the point of intersection of the system of equations,

  you will solve the graphically or algebraically

- Graphically by drawing two lines on the coordinate plane

- Algebraically by substitution method or elimination method

* Lets use the substitution method

∵ y = 4 - x

∵ 2y = 8 - 2x

- Substitute y in the second equation by its value in the

 first equation

∴ 2(4 - x) = 8 - 2x ⇒ open the bracket

∴ 8 - 2x = 8 - 2x

* The two sides equal each other, that means we can use any

  vales of x, and on the graph they will be the same line for

  the two equations

∴ This system of equations has infinite points of intersection
