Why does it make sense that 4 x (-3) and -3 x 4 have the same product?

Answer:

hello!!!

We will learn it simple method,we know that multiplication of whole numbers is repeated addition. For example

3*4= 4+4+4

in this same way we can say that

[-12]=(-3)+(-3)+(-3)+(-3)

also,

4(*-3)=(-12)

for the second equation we can take it same as the above one

So it make no diffrence when we multiplied integers as (positive)*(negative) OR (NEGATIVE)*(POSITIVE)

And so now we can say

FOR ANY TWO POSITIVE INTEGER a and b WE CAN SAY

 (-a) *(b) = (-b)*(a) = -(a*b)

HOPE FULLY U MAY LIKED MY ANSWER GIVE POSITIVE FEEDBACK AND IF WANTS ANYTHING OTHER YOU MAY ASK ME IN COMMENT

Segment AB is on the line y − 4 = −5(x − 1), and segment CD is on the line y − 4 = one fifth(x − 5). Which statement proves the
Genrish500 [490]

Answer:

Segments AB and CD are perpendicular to each other.

Step-by-step explanation:

If you were to convert line segments AB and CD into slope-intercept form(y=mx+b), you would get y=-5x+1 for AB and y=1/5x-5.

Any line with a slope that is flipped-oppisite (-5/1 to -1/5 to1/5)

of another line must be perpendicular to each other. It doesn't have to have the same y-intercept, it just makes the intersecting point different.

Signal mistakenly produced 1,000 defective cell phones. the phones cost $60 each to produce. a salvage company will buy the defe
zhannawk [14.2K]
We are asked to solve for the incremental net income from reworking the phones.
Number of items = 1000
Production Cost = 1000*$60 = $60,000
Salvage value = 1000*$30 = $30,000
Rework Cost = 1000 *80 = $80,000
Price when resold = 1000 * $120 = $120,000

Incremental Net = $120,000 + $30,000 - $60,000 -$80,000
Incremental Net = $10,000

The answer is $10,000.

Aliun [14]
X+6x=56. 7x=56. Divide each side by 7 to get x=8. So Edna has 48 marbles. Sam has 8 marbles. She has 40 more marbles. Hope this helps! ;)

Please If you can see if you can help on some of my questions!!!!

PQ // BC 

then

Angle P = Angle B, A is common angle the two triangles are similar

AP/AB  = AQ/AC

8/18 = 12/ AC

AC = 12 * 18/8 = 27 (your ans: D)

AQ + QC = AC

QC = AC - AQ = 27 - 12 = 15 (if it was required) 

tan60 = y/8

y = s tan60 = 8sqrt(3)  (B)

Next time, post each question separately.
