Only B and C are correct
Step-by-step explanation:
Answer:
(3,2) Choice C
Step-by-step explanation:
x-2y = -1
2x+3y =12
multiply the first equation by -2
-2x +4y = 2
add the 2 equations together
2x+3y =12
-2x +4y = 2
-----------------
7y =14
divide by 7
y =2
x-2y = -1
x -2(2) = -1
x-4 = -1
add 4 to each side
x = 3
(3,2)
Answer:
75
Step-by-step explanation:
Average needed to get grade C = 70
Average = Total Amount / No of Items.
No of items = 4
therefore Total needed = 70 x 4 = 280
current total score = 66.75 + 66 + 72.25 = 205
the fourth test minimum score = 280 - 205 = 75
Never due to if they have different slopes they can only have 1 solution.
