5. which of the following is a solution to x2 – x – 6 = 0?
a
b
c
d
-3
-2
-1
2

x² - x - 6 = 0

x²- (3 - 2)x - 6 = 0

x² - 3x + 2x - 6 =0

x(x - 3) + 2(x - 3) = 0

(x - 3) (x + 2) = 0

x - 3 = 0

x = 3

x + 2 = 0

x = -2

x= 3 and x = -2

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
