a) x^7*x^4 = x^11
b) (x^3)^3 = x^9
c) m^14/m^2 = m^12
d) (x^2y^2)^4 = x^8y^8
e) x^5y^11 / x^2y^3 = x^3y^8
f) 2x^12/8x^2 = x^10 / 4
Answer: (-2,-11)
Step-by-step explanation:
We looking for values that will satisfy the equation upon inspection, when x is -2, the equation gives y=-11 .
I.e y=4x-3 ,when x=2
Y= 4(-2)-3
Y= -8-3
Y= -11
The answers 3 because median means middle :)
6x-7=4x+7
6x=4x+14
2x=14
x=7
Answer:
115 bacteria
Step-by-step explanation:
The function that gives the number of bacteria in a science experiment is:
f(x) = 30(1.4)^x
Where x is the number of days
After 4 days (x = 4), the number of bacteria will be:
f(4) = 30 * (1.4)^4
f(4) = 39 * 3.8416
f(4) = 115.248 = 115 (To the nearest whole number)
The number of bacteria after 4 days is 115.
