Solve the system
x+3y=22
2x-y=2

 The required solution is (x, y) = (4, 6).

Step-by-step explanation:  We are given to solve the following system of equations :

From equation (ii), we have

Substituting the value of y from equation (iii) in equation (i), we get

From equation (i), we get

Thus, the required solution is (x, y) = (4, 6).

b

step-by-step explanation:

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

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

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

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

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265
