I'm giving the brainlies to the best anwser. ∆abc has coordinates of a(-6,-7), b(4,-2),and c(0,7). find the coordinates of its image after a dilation centered at the origin with a scale factor of 2. a(–12, –14), b(8, –4), c(0, 14) a(–12, –7), b(8, –2), c(0, 7) a(–3, –3.5), b(2, –1), c(0, 3.5) a(–6, –7), b(4, –2), c(0, 7)

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
