12y(5y-7)(4y+9)=0
please show step by step to solve

y=0,y=7/5,y=-9/4

Step-by-step explanation:

12y(5y-7)(4y+9)=0

Using the zero product property

12y =0   (5y-7) =0  (4y+9)=0

12y/12 =0/12      5y-7 +7 =0+7     4y+9-9=0-9

y =0                        5y = 7               4y = -9

                              5y/5 = 7/5        4y/4 =-9/4

                                y = 7/5              y =-9/4

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
