Open circle means that it doesn t include the point in this case 8 it s moving to the right so to the + zone so x>8
Answer:
YES
Step-by-step explanation:
Given the equations representing two lines:
2x - y = -3 ----› Equation 1
-6x - 2y = -6 -----› Equation 2
Multiply equation 1 by 2, and multiply equation 2 by 1.
2x - y = -3 ----› Equation 1 × 2
-6x - 2y = -6 -----› Equation 2 × 1
4x - 2y = -6
-6x - 2y = -6
Subtract both equations
10x = 0
Divide both sides by 10
x = 0/10
x = 0
Substitute x = 0 into equation 1
2x - y = -3
2(0) - y = -3
0 - y = -3
-y = -3
Divide both sides by -1
y = 3
Thus, the solution would be (0, 3).
Variation are of 2 types: Direct variation that states 'if x increases, y increases'. And inverse variation which states ' if x increases, y decreases and y increases x increases'.
1. The amount of fuel used on a trip increases as the size of the car increases and as the distance traveled increases. = Direct variation
2. As the number of people helping mow a lawn increases, the time it takes to mow the lawn decreases = Inverse variation
3. The cost of having a house painted increases as the size of the house increases. = Direct variation
