Plz answer both questions 15 points
anyanavicka [17]

Answer:

If the signs of rational numbers are same, then the answer is positive.

If the signs of rational numbers are different, then the answer is negative.

Step-by-step explanation:

Consider the provided information.

A: When multiplying or dividing rational numbers, when will the answer be positive?

If we are multiplying or dividing rational numbers the answer will be positive if and only if both the rational numbers have same sign.

For example: Multiply 2 and 4.

2×4=8              (same sign)

or

Multiply -2 and -4.

-2×-4=8         (same sign)

8 is a positive rational number.

Now divided 2 and 4.

\frac{2}{4} =\frac{1}{2}    

or

Divided -2 and -4.

\frac{-2}{-4} =\frac{1}{2}

1/2 is a positive rational number.

Hence, If the signs of rational numbers are same, then the answer is positive.

B: When multiplying or dividing rational numbers, when will the answer be negative?

If we are multiplying or dividing rational numbers the answer will be negative if and only if both the rational numbers have different sign.

For example: Multiply 2 and -4.

2×-4=-8              (different sign)

or

Multiply -2 and 4.

-2×4=-8             (different sign)

-8 is a negative rational number.

Now divided 2 and -4.

\frac{2}{-4} =-\frac{1}{2}

or

Divided -2 and 4.

\frac{-2}{4} =-\frac{1}{2}

-1/2 is a negative rational number

Hence,  If the signs of rational numbers are different, then the answer is negative.

Write an equation in point-slope form for the line through the given point with the given slope
Neko [114]

Point-slope form:

y - y₁ = m(x - x₁)             "m" is the slope


Since you know:

m = -2/5

(x₁ , y₁) = (-3, -5)

Plug it into the equation:

y - y₁ = m(x - x₁)    

y - (-5) = -2/5(x - (-3))

y + 5 = -2/5(x + 3)
