Answer:
a) 12 points
b) A: 3 questions; B: 2 questions
Step-by-step explanation:
The least number of points each section may have is the least common multiple of 4 and 6. That is a number that will have all of the factors of 4 and all of the factors of 6: 2×2×3 = 12.
<h3>a)</h3>
Each part is worth 12 points.
<h3>b)</h3>
Part A has 12/4 = 3 questions.
Part B has 12/6 = 2 questions.
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)
