What is the equation for the values in the table
devlian [24]

Step-by-step explanation:

Taking any two points through which the line passes;(-10,-3) and (-5,-1)

The equation of the line is given by

\frac{y2 - y1}{x2 - x1}  =  \frac{y - y1}{x - x1}

=>  \frac{ - 1 - ( - 3)}{ - 5 - ( - 10)}  =  \frac{y - ( - 3)}{x -  ( - 10)}  =  \frac{y + 3}{x + 10}

=>  \frac{ - 1 + 3}{ - 5 + 10}  =  \frac{y + 3}{x + 10}

=>  \frac{2}{5}  =  \frac{y + 3}{x + 10}

=> 5(y + 3) = 2(x + 10)

=> 5y+15 = 2x+20

=> 5y =2x+5

=> y= \frac{2}{5} x + 1

option C

What is equation created from the sqrt(x+2)+2))^2
Naddika [18.5K]

Answer:

x + 4√(x + 2) + 6

Step-by-step explanation:

All we need to do is expand by using FOIL (First, Outside, Inside, Last):

x + 2 + 2√(x + 2) + 2√(x + 2) + 4

Then we combine like terms to get our final answer:

x + 2 + 4√(x + 2) + 4

x + 4√(x + 2) + 6
