Solve the system: x-2y=1y=x+2substitution method provide explanation,

x=-5, y=-3

Step-by-step explanation:

Given the system of two equations

Substitute the second equation into the first one:

Then

5x+2x=49

7x=49

x=7. 35 apples

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
