The following problem can be modeled with a linear equation. analyze the problem and identify what quantities the variables x and y represent. the information provided in the problem is adequate to determine a point and a slope or two points on the line.
robinson wholesale company paid $1370 for 500 items. later they bought 800 items for $1730. assume that the cost is a linear function of the number of items. write the equation. (let y represent the amount paid and x represent the number of items purchased.)

6x-5y+3850=0

Step-by-step explanation:

If y represents the amount paid and x represents the number of items purchased, then the information provided is two points on the line:

We can find the equation with the next formulas:

having a point and a slope m:

having two points:

Substitution:

clearing y:

Where the slope m=6/5 and the intersection with y-axis is 770.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

y = i/2 xtnop + (3i/2 tnop+ 1)
