Show that the equation x2 – 5xy + 4y2 + 2x = 8y represents two straight lines.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
