the 1st one
step-by-step explanation: imaginary number-that is expressed in terms of the square root of a negative number (usually the square root of −1, represented by i or j ).
i think is sss
sss similarity theorem. by definition, two triangles are similar if all their corresponding angles are congruent and their corresponding sides are proportional. sss similarity theorem: if all three pairs of corresponding sides of two triangles are proportional, then the two triangles are similar.
a. y = -1x +4
b. y = 1x +8
for a it intercepts 4 for y. as you can see, it k intercepts with j at (-2,6). it is moving 2 to the left and 2 up. when you use rise over run, x equals -1/1 (because you move from left to right).
hopefully this you.
find annual profit: $75,000/6 = $12,500
roi = annual profit/ initial investment
roi = $12,500/$15,000 or 83.3%
