Mathematics
1 answer:
Andrews [41]3 years ago
4 0

Answer:

see below

Step-by-step explanation:

6.   -3x^2+9=-3

           -3x^2 =-12

               x^2=4

                x= ±2

Solution: x=2, x=-2

Points of intersection:  (2, -3) and (-2, -3)

7.         (x-2)^2-10\leq (x-6)^2-2

     x^2-4x+4-10\leq x^2-12x+36-2

                   -4x-6\leq -12x+34

                            8x\leq 40

                              x\leq 5

Solution:  x\leq 5

Point of intersection is (5, -1)

Susan and John are buying cold drinks for a neighborhood picnic. Each person is
givi [52]

Answer:

Susan has suggested a correct method to calculate the amount of money

Step-by-step explanation:

Here we must check what each person is calculating. First, we consider Susan's method. She has suggested that we multiply the cost per soda, that is dollars/soda by the number of sodas required, we get the total cost.

Assuming that 18 sodas are required and each costs $0.20, the total cost according to Susan is $3.60.

John suggests we divide the cost of a 12 pack of soda by the number of sodas required. Considering a 12 pack of soda costs $12 and the same amount of sodas, 18, are required, we get that each soda costs $0.66.

Looking at these answers, we see that Susan has suggested a correct method to calculate the amount of money needed to buy a number of sodas. John has suggested the amount each person would have to contribute if everyone at the party was trying to buy a 12-pack of soda; regardless of whether more or less than a 12-pack is required.
