7. (1,2),(0,-1)
slope = (-1 - 2) / (0 - 1) = -3/-1 = 3 <==
8. (-1,0),(1,-1)
slope = (-1 - 0) / (1 - (-1) = -1 / 2 <==
AD = √(19^2 + 3^2)
AD = √370
AD = 19.2
answer
C. 19.2
Answer: {y,x} = {4,2} ) ) ) )4
Step-by-step explanation: y
[2] y = -2x + 8
// Plug this in for variable y in equation [1]
[1] (-2x+8) - x = 2
[1] - 3x = -6
// Solve equation [1] for the variable x
[1] 3x = 6
[1] x = 2
// By now we know this much :
y = -2x+8
x = 2
// Use the x value to solve for y
y = -2(2)+8 = 4
Solution :
{y,x} = {4,2}
Well first your gonna use the strategy called pemdas. Do you know howw to work with pemdas?
Answer:
3.4 tonnes
Step-by-step explanation:
