Alex787 [66]
The system of linear equations that may be used in order to solve this problem is as follows:

x + y = 37
2x + 3y = 95

This is considering that x is the number of bracelets sold and y is the number of necklaces.

The values of x and y in the equation are 16 and 31, respectively.

Thus, the answer is 16 bracelets and 21 necklaces.

Give the equation of the line that passes through the points (4,6) and (-2,3)
Nutka1998 [239]

Answer:

y = 1/2x+4

Step-by-step explanation:

First we find the slope

m = (y2-y1)/(x2-x1)

    = (3-6)/(-2-4)

    = -3/-6

   =1/2

The equation of a line in slope intercept form is

y = mx+b  where m is the slope and b is the y intercept

y =1/2x+b

Substitute one of the point into the equation

6 = 1/2(4) +b

6 = 2+b

b=4

y = 1/2x+4
