Answer:

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

Find an equation of the line having the given slope and containing the given point.

mart [117]

Answer:

y=8x-69

Step-by-step explanation:

you would use the equation y-y1 = m (x - x1)

plug in m = 8 , y1 = 3, x1 = 9

now you have y - 3 = 8 (x-9)

distribute 8 --> y-3 = 8x - 72

add three to both sides to get y = 8x - 69

If a town with a population of 10,000 doubles every 14 years, what will the population be in 42 years and is it modeled by a lin

madreJ [45]

This is an exponential function.
The starting population is: 10,000 and it doubles every 14 years.
In 42 years ( 42 : 14 = 3 ) the population doubles 3 times.
The equation ( exponential ) is :
y = 10,000 * 2^n
In this case: n = 3
y = 10,000 * 2 ^3 = 10,000 * 8 = 80,000
Answer: In 42 years the population of this town will be 80,000.
