The third table would be your answer.
I know this because I turned both equations shown into graph form, this allowed me to see what the x-values of 1, 2, and 3 would have for y-values. My graph of both equations is shown in the picture below. (Green is f(x) = x + 4 and purple is g(x) = -2f(x))
Yes, J can be determined if H=54. The interior angles of a triangle always add up to 180. Since we know H=54 and J and I are equal.
J+I+H=180
J+I+54=180
J+I= 126
Because J&I are equal you can just divide 126 by 2
J=126/2
J= 63
Answer:
y=21-3x and y=18-2x
Step-by-step explanation:
Ok, so we have candle A, which is 21 inches and burns 3 inches every hour. in slope-intercept form, the hours would be the x, the 21 is our y intercept. So the first equatio would be y=-3x+21 (negative slope, because the height of the candle is going down). Candle b, which is 18 inches, burns away 2 inches each hour. We can make -2 the slope (negative 2, since the candle is being burned away, not being added to), and the 18 our y intercept. So the two equations would be
y=21-3x
and
y=18-2x
