Answer:
no
Step-by-step explanation:
if the ratio (yx) of two variables (x and y) is equal to a constant (k=yx) .in this case y is said to be directly proportional to x with proportionality constant k

Step-by-step explanation:
Yasmina:
5.25 x 5 = 26.25 per week
5.25 x 20 = 105 per month
5.25 x 260 = 1365 per year
Camila:
9.75 x 35 = $ 341.25 earnings per week
341.25 x 0.20 = 68.25 saves per week
9.75x35x 4= 1365 earnings per month
1365 x 0.20 = 273 saves per month
9.75 x 35 x 52 = 17745 earnings per year
17745 x 0.20 = 3549 saves per year

Answer:
(x - 3)(x + 1)(x + 5)
Step-by-step explanation:
I'd use synthetic division instead. If we were to find the roots of the given polynomial, we could from them write the factors as well.
The divisor x + 5 corresponds to root x = -5. Setting up synthetic div.,
-5 ) 1 3 -13 -15
-5 10 +15
-----------------------------
1 -2 -3 0
Since the remainder is 0, we know that -5 is a root and (x + 5) is a factor. Moreover, we know that the coefficients of the quotient are 1, -2 and -3.
1x² - 2x - 3 can be factored: the factors are (x - 3) and (x + 1).
So the end result for this problem is (x - 3)(x + 1)(x + 5).
