Please solve the simultaneous equation below in the form x= ..., y=..., x= ..., y=... x² - xy = 0
x + y = 1

Try this suggested option, the answer is underlined with colour (x=0, y=1; x=y=1/2).

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
