Answer:
linear and increasing
Step-by-step explanation:
20x + 11y = 37
4x + 3y = 13
Enter the correct answer.
Answer: x= -2 and y=7
Step-by-step explanation:
4×20x+11y=37
20×4x+3y=13
Using elimination method
80x+44y=148
80x+60y=260
-16y/-16=-112/-16
Y=7
Substitute for Y in equation (1)
20x+ 11(7)=37
20x+77=37
20x=37-77
20x/20= -40/20
X= -2
therefore, x=-2 and y=7
1. x2 = x ____
2. (xy) 2 = _____ (yz)
Answer:
1. x^2 = x * x
2. (xy)^2 = x^2 * y^2
Answer: 1. x^2 = x * x Hope it helps
