Answer:
Step-by-step explanation:
The four steps of linear combination method are
1) Rearrange like terms such that they are in the same column.
2) The next step is to decide on which variable you want to eliminate and multiply each row with suitable numbers that would make the coefficient of the variable to be equal and opposite.
3) Add both rows and solve for the other unknown variable.
4) substitute the known variable into any of the equations and solve for the other variable.
4x + 2y = 5
−4x − 5y = 7
We would eliminate x by adding both equations. It becomes
- 3y = 12
y = 12/- 3 = - 4
Substituting y = - 4 into the first equation, it becomes
4x + 2 × - 4 = 5
4x - 8 = 5
4x = 5 + 8 = 13
x = 13/4 = 3.25
The correct option is option B : -4 ≤ x ≤ 1

What is Increasing and decreasing function?</h3>
Increasing and decreasing functions are functions whose graphs go upwards and downwards respectively as we move towards the right-hand side of the x-axis. Increasing and decreasing functions are also called non-decreasing and non-increasing functions.
Here, from graph
as we can observe from x = -4 graph starts increases upto x = 1 and after that graph becomes constant.
Thus, between x belongs -4 to 1 the graph is increasing.

It is -12<n<-11 so it is between that
Answer:
If a Poisson process applies, we have the probability that k potholes are find in t miles as:
The probability that no more that one pothole will appear in a section of one mile is P=0.1353.
The probability that no more that 4 potholes will occur in a given section of 5 miles is P=0.0293.
Step-by-step explanation:
We have the rate of potholes:
If a Poisson process applies, we have the probability that k potholes are find in t miles as:
The probability that no more that one pothole will appear in a section of one mile is P=0.1353:
The probability that no more that 4 potholes will occur in a given section of 5 miles is P=0.0293:
Answer:
1) 10^2 + 1
2) ?
3) 2(3^3) + 11
4) 16^2 - 79
Step-by-step explanation:
1) 101 = 100 +1 = 10^2 +1
2) ?
3) 173 = 81+81+11 = 3^3+3^3+11 = 2(3^3) +11
4) 177=256-79 = 16^2 -79
