Answer:
Step-by-step explanation:
Given that,
y=x+2 equation 1
2x-y=-4 equation 2
This is a simultaneous equation.
Substitute equation 1 into equation 2
2x-y=-4. Since y=x+2
2x-(x+2) = -4
2x-x-2 = -4
x-2 = -4
x = -4+2
x = -2
Also from equation 1
y=x+2
Since x=-2
y=-2+2
y=0
Then, solution (x, y) = (-2,0)
Answer:
Step-by-step explanation: Need to work out your scale factor which is 1.5.
8 * 1.5 = 12
CE = 12
12 * 9 = 108/2 = 59 that is the area of triangle ACE
8 * 6 = 48/2 = 24 that is the area of triangle BCD
ACE - BCD = ABDE
59 - 24 = 35cm^2
Answer:
The correct option is the third: All positive real numbers
Step-by-step explanation:
The domain of this function are all possible values that x can take. If we are talking about the number of miles traveled, these can be as many as the client travels (20.5, 670.23, etc), or zero, if not traveled any. But x can never be less than zero, since it would be absurd for a customer to have traveled -20 miles, for example. Therefore x can take any positive value. The domain of the function is
x> 0
The correct option is the third: All positive real numbers
