Answer:
2x - y = -7
Step-by-step explanation:
The equation y = 2x+7 needs to be written in standard form where A must be positive.
To convert to standard form, subtract 2x from both sides.
-2x + y = 7
Multiply each term by -1.
-1(-2x + y =7)
2x - y = -7

Answer:
22.4 hours
Step-by-step explanation:
The population of bacteria is modelled by the equation:
From the the question, the initial population of bacteria is 720.
So after 26 hours, we have:
This implies that:
We want to find how long it will take for there to be 1310 bacteria present.
To the nearest tenth , it will take 22.4 hours
Answer:
A) an upper quartile of 56 and a median of 50
Step-by-step explanation:
Hello!
The lower and upper ends "box" from the box and whiskers plot is determined by the first (Q₁) and third (Q₃) quartiles of the data set and the line inside the box marks the median or second quartile of the sample (Q₂)
The length of the whiskers of the diagram is determined by the minimum value (left whisker) and the maximum value (right whisker)
If you observe the graphic:
Q₁= 42
Q₂= 50 (Median)
Q₃= 56
Min= 38
Max= 66
The box is delimited by a lower quartile of 42 and an upper quartile of 56, with a median 50, the least observation is 38 and the highest observation is 66.
The correct choice is A.
I hope this helps!
