Which of the following equations has the same solutions as x^2+8x+2=0
denis23 [38]

Answer:

See below

Step-by-step explanation:

Need the choices.....

     essentially,  you can multiply this equation  by any constant to get an equivalent equation with the same solutions.

x^2 + 8x + 2 = 0      multiply both sides by '3' to get

3x^2 + 24 x + 6 = 0     <===== this will have the same solutions

    or this one:

x^2 + 8x + 2  = 0            Multiply both sides by   '6' to get

6x^2 + 48x + 12 = 0      <===== this will have the same solutions also

etc....

2(x + 4) − 1 = 2x + 7
Margarita [4]

Answer:

All real numbers are solutions to this problem.

Step-by-step explanation:

I) Simplify:

2(x + 4) - 1 = 2x + 7

x + 4 - 0.5 = x + 3.5 (Divide by 2)

x + 3.5 = x + 3.5 (Simplify <em>x + 4 - 0.5</em>)

x = x

II) Conclusion:

Any real number will work as a solution.

Which linear inequality is represented by the graph
Anarel [89]

Answer:

the second choice

Step-by-step explanation:

The last two choices could not be correct, because it would need a dashed line.  The line under the greater than or less than symbol mean  that the line is included in the answer and it will be a solid line like you see in the picture.  For both of the top two answers the slope that they y intercept is correct.  You just have to decide is the symbol will be greater than or equal to or less than and equal to.  

If we put 0 in x for in the form y = mx + b, what would y be?

y = 1/3 x - 1

y = 1/3(0) - 1

y = -1

The ordered pair is (0,1).  That is the part that is shaded so that shows us that the second answer is correct.
