A system of equations is shown below. Equation 1: 2x-y=-8
Equation 2: x+2y=6
To begin solving the system of equations, Equation 1 is multiplied by a value of 2 to create Equation 3.
Equation 3: 4x-2y=-16
Equation 2: x+2y=6
Which procedure could best be used to eliminate one of the variables?

square root

step-by-step explanation:

answer: 10 turtles

step-by-step explanation: as turtles have four legs so 4.10=40 therefore birds are 4 which sue counted

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

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21
