Answer:
y = 2x +7
Step-by-step explanation:
We are given two points on the growth curve: (weeks, ounces) = (2, 11) or (4, 15).
These can be used to write the equation of a line using the 2-point form:
y = (y2 -y1)/(x2 -1x)(x -x1) +y1
y = (15 -11)/(4 -2)(x -2) +11
y = 4/2(x -2) +11
y = 2x +7 . . . . . y = weight in ounces x weeks after birth

<em>Comment on the problem</em>
There are an infinite number of equations that can be written to go through the two given points. A linear equation is only one of them.
Answer:The Collatz conjecture is a conjecture in mathematics that concerns a sequence defined as follows: start with any positive integer n. Then each term is obtained from the previous term as follows: if the previous term is even, the next term is one half the previous term. If the previous term is odd, the next term is 3 times the previous term plus 1.
Step-by-step explanation :an opinion or conclusion formed on the basis of incomplete information.
Answer:
The train was travelling at 60 km/h
Step-by-step explanation:
We're already given time and distance, and speed is just distance/time, so:
240km / 4h
= (240/4) km/h
= 60km/h
Step-by-step explanation:
F ( x ) = x² + 2x - 24
{ factorising by middle term splitting method }
[ 24 = 2 × 2 × 2 × 3 ]
F ( x ) = x² + 6x - 4x - 24
F ( x ) = x ( x + 6 ) -4 ( x + 6 )
F ( x ) = ( x + 6 ) ( x - 4 )
