Answer: C
Step-by-step explanation:
(-2) (4) is negative
(-6)(-3) is postive
negative * positive = negative
Negative, because the product (−2)(4) is negative and the product (−6)(−3) is positive, and the product of a negative number and a positive number is a negative number

Answer:
Part 1)
Part 2)
Step-by-step explanation:
<u><em>Analize two problems</em></u>
Part 1) If y varies directly with x, and If y=-8 and x= -3 what’s x when y= 6
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
step 1
Find the value of the constant of proportionality k
For x=-3, y=-8
substitute the given values
step 2
Find the linear equation
step 3
Find the value of x when y=6
substitute the value of y in the linear equation
solve for x
simplify
Part 2) If y varies inversely with x, and If y=-8 and x= -3 what’s x when y= 6
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form or
step 1
Find the value of the constant of proportionality k
For x=-3, y=-8
substitute the given values
step 2
Find the equation
step 3
Find the value of x when y=6
substitute the value of y in the equation
solve for x
26 = 5 (x + 10) + 3x
26 = 5x + 50 + 15x
26 = 5x +15x + 50
26 = 20x + 50
26 - 50 = 20x - 50
-14 = 20x
-14 / 20 = x
-0.7 = x
