If y varies directly as x and y=288 when x=16 determine the value of y when x-13
1 answer:
Y = kx is the direct variation equation
Substitute the x and y that are given to find k then write your new equation in terms of y with the k.
288 = k(16) divide by 16 to find k
18 = k
Now write the new equation
y = 18x
y = 18(13) or y = 18(-13) I'm not sure by what you have typed if that is supposed to be and equal sign or a negative.
y = 234 OR y = -234

4/3 as decimal is 1.3333 and so on and 2 3 and 4 as a decimal is 2.34
Answer:
-9/11
Step-by-step explanation:
The slope of the line is given by
m = (y2-y1)/(x2-x1)
= (9-0)/(-3-8)
= 9/-11
= -9/11
