Answer:
you can use reciprocal and quotient formula of trigonometry
Answer:
Point the point on the graph (3,-7) by find 3 on the x axis (horizontal line) and than going down -7 coordinates. and then start plotting points that are at a slope of 1/3 so you would go up 1 from the point (3,-7) and than go 3 right and then plot a point, and keep doing that to make a lot of points that create a straight line at the end when you connect them!
hope it helped!
ALGEBRA M8 SOZ
Length = L, Width = W
L = 20 + 2W,
2L + 2W = 610.
then u gotta do some inspiring expression-algebra-maths stuff to work it out :)
(x - 4)(x^2 + 3x + 2) =
x(x^2 + 3x + 2) - 4(x^2 + 3x + 2) =
x^3 + 3x^2 + 2x - 4x^2 - 12x - 8 =
x^3 -x^2 - 10x - 8
x would equal 2 because:
4 times 5 is 20
4 times 2x is -8x
move over the 8x to the side with the 2x
then you have 10x=20
20/10 equals x=2
Hope this helps :)
