Answer:
{x = 1/7
,y = 1
Step-by-step explanation:
Solve the following system:
{-5 y = -5 | (equation 1)
{7 x + 6 y = 7 | (equation 2)
Swap equation 1 with equation 2:
{7 x + 6 y = 7 | (equation 1)
{0 x - 5 y = -5 | (equation 2)
Divide equation 2 by -5:
{7 x + 6 y = 7 | (equation 1)
{0 x+y = 1 | (equation 2)
Subtract 6 × (equation 2) from equation 1:
{7 x+0 y = 1 | (equation 1)
{0 x+y = 1 | (equation 2)
Divide equation 1 by 7:
{x+0 y = 1/7 | (equation 1)
{0 x+y = 1 | (equation 2)
Collect results: Answer: {x = 1/7
,y = 1
Answer:
Sum is addition.
That's multiplication
Bcz im so nice, i'll put both answers
71904 = multiplication
845 = addition
Perpendicular = opposite sign and reciprocal slope
Slope: 2 turns into -1/2
Y = -1/2x + b
2 = -1/2(2) + b, b = 3
Equation: y = -1/2 + 3
Answer:
240 - 145 = 96.
i dont know if this helped, this is unfinished.
