Answer:
YES. (2, 7) is a solution of the system.
Step-by-step explanation:
System of linear inequalities has been given as,
y ≥ -x + 1 --------(1)
y < 4x + 2 ------(2)
If (2, 7) is a solution of the given system of inequalities, it will satisfy both the inequalities.
By substituting the coordinates of point (2, 7) in inequality (1),
7 ≥ -2 + 1
7 ≥ -1
True.
By substituting the coordinates of point (2, 7) in inequality (2),
7 < 4(2) + 1
7 < 9
True.
Therefore, point (2, 7) lie in the solution area of system of inequalities.
YES. (2, 7) is a solution of the system.
Hello! :D
Equation: 
The simplified answer: -0.75
Hope this helps! Have a wonderful day! :D
Answer:
X<-8
Step-by-step explanation:
-1/2x>4
Multiple both sides by -2
-2(-1/2)x<-2(4)
Multiple even numbers of negative terms
2(1/2)x<-2(4)
Cancel out the 2
(2 this is out)(1/(2 this is out))x<-2(4)
x<-2×4
Multiple
x<-8
To do this we need to see how many degrees it dropped then divide by time (15 hr.).
52 - (-23)
75
75/15
5 deg/hr
Hope this helped!
Answer:
20k
Step-by-step explanation:
if he can run 10k in 30 minutes, and 30 minutes is 1/2 of an hour, then you can say that he can run 10k(2) or 20k in an hour.
