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:
WZX = 110
y = 19
Step-by-step explanation:
We can create the following equation to solve for y.
Reduce
4y = 76
y = 19
We then plug into 4y + 34 to get angle
WZX = 110
Answer:
B
Step-by-step explanation:
cause it's got a 5.....5 x 5 = 25.......make sense
Answer:
Option c
Step-by-step explanation:
if x = 12
12^2 = 144
144/18 = 8
28 + 8 = 36
<u><em>Answer: m=2 and 2=m *The answer should be have positive sign.*</em></u>
Step-by-step explanation:
4m-7+10=15-2m ← Group like terms
add/subtract numbers
-7+10=3
4m+3=15-2m
subtract by 3 both sides of an equation.
4m+3-3=15-2m-3
simplify.
4m=-2m+12
add 2m both sides of an equation.
4m+2m=-2m+12+2m
simplify.
6m=12
divide by 6 both sides of an equation.
6m/6=12/6
simplify by equation.
12/6=2
6*2=12
2*6=12
12/2=6
m=2
Hope this helps!
Thanks!
Have a great day!
