Answer:
The answer is below
Step-by-step explanation:
The equation of a linear function is given as:
y = mx + b;
where y, x are variables, m is the rate of change and b is the initial value of variable y.
A) Since there is B bacteria in the Petri dish at 12:00 midnight and the number of bacteria increases after midnight by 25 every hour. Let h represent the time in hours and T represent the total number of bacteria, therefore the equation is:
T = 25h + B
B) Given that B = 5, h = 6, hence:
T = 25(6) + 5 = 150 + 5 = 155 bacteria
C) The equation of the graph is:
T = 25h + 5
The graph was plotted using geogebra online graphing.
Answer:
b = 22
Step-by-step explanation:
3b-16=50
3b = 66
b = 22
Answer:
Domain is the values that x can take. In terms of real numbers x can take any value and the function will make sense. Since this is linear function the range is not limited too. So the range and domain coincide and are (-infinity;infinity)
Answer:
y = x + 7
Step-by-step explanation:
x = number of weeks
y = the total number of quizzes y.
<em>Cole has already taken 7 quizzes = </em>+ 7
<em>he expects to have 1 quiz during each week of this quarter = </em>1x
y = 1x + 7
y = x + 7
