9. A hot cup of coffee cools according to the equation IT * (t) = 68 * (1/2) ^ (1/22) + 18 where T(t) the temperature, in degrees Celsius, and is the time in minutes . a) Which part of the equation indicates that it models exponential decay ? b) What value of t makes the exponent in the equation equal to 1? c) What is the significance of this value? d) What was the initial temperature of the coffee e) Determine the temperature of the coffee after 40 min to the nearest degree

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

homozygous. one is homozygous, while two is heterozygous.
