To find the maximum for something pertaining to a liquid or etc.
I would love to use substitution (It is simplier that way I guess)
solve your system of equations.
x+2y=−1;x−y=5
Solve x+2y=−1 for x:
x+2y+−2y=−1+−2y(Add -2y to both sides)
x=−2y−1
Substitute (−2y−1) for x in x−y=5:
x−y=5
−2y−1−y=5
−3y−1=5(Simplify both sides of the equation)
−3y−1+1=5+1(Add 1 to both sides)
−3y=6
−3y/−3 = 6/−3(Divide both sides by -3)
y=−2
Substitute (−2) for y in x=−2y−1:
x=−2y−1
x=(−2)(−2)−1
x=3(Simplify both sides of the equation)
So the answer is (x = 3 and y = -2)
Answer: Line R and Line P are perpendicular because they intersect at a point and create a pair of equal angles.

Step-by-step explanation:
2/3 x 3/4 = 2x3/3x4 = 6/12 = 1/2
Answer: Thus both of them got it correct
Step-by-step explanation:
Step 1
Andy finds the sale price of a baseball glove that normally costs $49 by evaluating the question 49 - 0.3(49).
the Price will be 49-14.7=34:3
Step 2
Juan finds the sale price by multiplying 0.7(49).
0.7x 49 =34.3
