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.
Answer:
1 + 12
Step-by-step explanation:
Let's do this one step by step!
We are going to make sure that we pay attention to the part in the parenthesis first!
Let's multiply -2x with -6 first.
Equation:
4+(-3)-2x(-6)
We do not need to parenthesis around the -3 because a negative cancels out a positive. So, no matter what you would have to subtract.
4 - 3 + 12x
And we get a positive 12 because both numbers that were being multiplied were negative.
Now let's combine common terms.
1 + 12x
This is your answer! I hope this helped!

Answer:
t = 11.
Step-by-step explanation:
7 -1(5t - 13) = -25.
Distribute the -1.
7 - 5t + 13 = -25
Combine like terms.
20 - 5t = -25
Subtract 20 from both sides.
-5t = -55
Divide by -5.
t = 11.
Answer:
2000
Step-by-step explanation:
38.
R = 90x - x²
R = 90(50) - 50²
R = 4500 - 2500
R = 2000
