Answer:
x=3
y=5
Step-by-step explanation:
x+5y=28 (i)
-x-2y=-13. (ii)
add equation 2 from equation 1
x+5y=28
-x-2y=-13
3y=15
y=5
put the value of y in equation 1
x+5y=28
x+5*5=28
x+25=28
x=28-25
x=3
Answer:
6x^4
Step-by-step explanation:
Answer:
Yes, because they are identical to eachother
Step-by-step explanation:
The equation that can be used to determine the number of cells after x hours is; y = 0.5x + 30.
<h3>Linear model Equations</h3>
It follows from the task content that;
- The scientist starts with a sample of 30 bacteria cells, it follows that the intercept of the linear model is 30.
Additionally, since the number of bacteria cells increases by 50% every hour implies that the rate of change, slope of the equation is 0.5.
Hence, the required equation is; y = 0.5x + 30.
