ackie cut a piece of paper along its diagonal, as shown below, forming two triangles. A rectangle is cut diagonally to form 2 equal triangles. How do the height and base length of the two triangles compare to the height and base length of the original piece of paper?

The height and base length are the same as the original paper.

Step-by-step explanation: It is hard without the picture. But if they cut it from corner to corner, then this is the answer.

A. The two dimensions are the same in the triangles as they were in the rectangle.

Step-by-step explanation:

i think its this, sorry if im wrong

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
