Damm [24]

Answer:

Step 2

Any quadratic problem will always have two solutions. Therefore since, we only have one solution here, it is wrong. The mistake was incurred in step 2;

  From the given problem ;

    <u> Wrong                                                  right</u>

    2(x + 4)² = 242

    (x + 4)² = 121     Step 1  

     x+4=11              Step 2                  x + 4  = ± 11

     x  = 7                Step 3                  x + 4  = 11 or x + 4  = -11

                                                           x  = 11- 4     or    x  = -11 - 4

                                                           x  = 7 or -15

What is the equation of the line that contains the point (-1, 4) and has a slope of 3?
sertanlavr [38]

Let's write the equation with formula:-

\boxed{ \sf \: formula : y -y_{1} =  m(x -  x_{1})}

Where,

  • x1 is -1 and y1 is 4 and m is 3

\tt \: y - 4= 3(x - ( - 1))

\tt \: y  - 4 = 3(x + 1)

\tt \: y  - 4 = 3x + 3

\tt \: y = 3x + 3 + 4

\tt \: y = 3x + 7

<em>Thus, The correct choice is option C!!~</em>
