x=7 and y=4
x = 6 So y = 9*6 + 4 = 54 + 4 = 58 The ordered pair is (6, 58)
9x + 3y = -54 3y = -9x - 54 y = -(3x + 18) Therefore, the y-intercept of this equation is y=-18.
54(x)+52+32(y)+72=212
x = y = 0 ?
x=7 and y=4
-54
x = 6 So y = 9*6 + 4 = 54 + 4 = 58 The ordered pair is (6, 58)
They are expressions.
x = 0 and y = 4
y=-10x-4
9x + 3y = -54 3y = -9x - 54 y = -(3x + 18) Therefore, the y-intercept of this equation is y=-18.
T = 3x + 7y; x = 4; y = 6T = 3x + 7y (substitute 4 for x, and 6 for y)T = 3(4) + 7(6) = 12 + 42 = 54
54(x)+52+32(y)+72=212
x = y = 0 ?
symmetric property
54/6 = 36/y So, y = 4
