How are the rules for dividing two negative fractions related to the rules for multiplying
two negative fractions? Will the answer be positive or negative? Explain.
The relation between multiplying and dividing two negative fractions is needed.
When multiplying and dividing two negative fractions the answer will be always positive.
Let [tex]-\dfrac{a}{b}[/tex] be one fraction
and [tex]-\dfrac{c}{d}[/tex] be another fraction
Let us multiply them
[tex]-\dfrac{a}{b}\times -\dfrac{c}{d}=+\dfrac{ac}{bd}[/tex]
Let us divide them
[tex]\dfrac{-\dfrac{a}{b}}{-\dfrac{c}{d}}[/tex]
This can also be written as
[tex]-\dfrac{a}{b}\times -\dfrac{d}{c}=+\dfrac{ad}{bc}[/tex]
Since, multiplication and division are the inverse of each other the negative signs cancel each other and the sign is positive.
Hence, when multiplying and dividing two negative fractions the answer will be always positive.

J''(- 3, 3 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x )
Thus J(1, 1 ) → J'(- 1, 1 )
Under a dilatation with scale factor 3, multiply each of the coordinates of J' by 3, that is
J'' = (3(- 1), 3(1)) = (- 3, 3 )

Solve for x using the
distributive property.
7(x + 3) = -49
Answer:
x= -10
Step-by-step explanation:
distribute 7 to x and 3: 7x + 21 = -49
subtract 21 from both sides to isolate the variable: 7x= -70
divide both sides by 7 to find x: x= -10
Answer:
X = -10
Step-by-step explanation:
1.- 7x + 21 = -49
Subtract 21 on both sides of the equal sign
You should have:
2.- 7x = -70
Divide 7 on both sides of the equal sign
You should get the answer:
X = -10

Answer:
I don't know if this is correct but it probably is but I got x=5
Step-by-step explanation:
you write the equation and put the line through the sign, and cross out the 3. Then you are going to add 3 to the seven which will then equal 2x > 10. Then you cross out the 2 and divide both side with the 2. and 10 divided by 2 is 5 so therefore x equals 5.
What is the minimum angle of rotation lin degrees that will carry the six-sided star onto itself?
What’s the degree
Answer:
120 degrees
Step-by-step explanation:
If it's a 6 sided star, that means that it will be divided into 3 parts (think about how a normal 5-point star has 10 sides). That means that we divide 360 (total number of degrees in a full rotation) by 3 (number of sections) = 120
