Does -7 • [-8] = 7• 8

Hey there!

Guide:

• Negative & negative = positive

• Positive & positive = positive

• Negative & positive = negative

• Positive & negative = negative

• Positives are above 0

• Negatives are below 0

• Negatives are on the left side of the number line

• Positives are on the right side of the number

Answering your question

-7 * -8 = 7 * 8

-7 * -8 = 56

7 * 8 = 56

56 = 56

YES they are equivalent/equal to each other because both of them equal positive 56.

• It wouldn’t be equivalent if one is a negative number and the other one is positive (even when it looks like the same number). If both numbers are positives / negatives with the same number then they’ll most likely be equivalent/equal to each other!

Good luck on your assignment and enjoy your day!

2? if not the correct answer you might need to provide more information

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
