Answer:
obtuse angle
Step-by-step explanation:
–2x + 4y = –7 . . . . . (1)
y = -1/2x + 5 . . . . . . (2)
Putting (2) into (1), we have:
-2x + 4(-1/2x + 5) = -7
-2x - 2x + 5 = -7
-4x = -7 - 5 = -12
x = -12/-4 = 3
y = -1/2(3) + 5 = -3/2 + 5 = 7/2
Hence, the system has one solution.
Step-by-step explanation:
put 3.9, 3.99,........ to 4.1 as value of x in ((x-4)÷(x^2-2x-4)) than you will get f(x)
80 oz and 5 lbs are the same
