You can verify the zeros of the function y=x2+6x-7 by using a graph and finding where the graph  C. <span>C. crosses the x-axis . Finding the zeros mean equating the equation to 0 or y =0. When y =0, this is equal to x-axis. C. is the answer to the problem given above. </span>

Answer:

the table:

x | y

-2 | 5

-1 | 3

0 |  1

1  | 3

Need some help, kinda stuck
ElenaW [278]

Answer:

7/4

Step-by-step explanation:

\displaystyle\frac{2 +  \sqrt{ - 3} }{2} ( \frac{2 -  \sqrt{ - 3} }{2} )~~~~~~

Evaluate.

Solution:

Rewrite it as,

  • \displaystyle\frac{2 +    \sqrt{  - 1 }  \sqrt{  3} }{2} ( \frac{2 -  \sqrt{ - 1}  \sqrt{3} }{2} )
  • \displaystyle\frac{2 +  i\sqrt{  3} }{2} ( \frac{2 -  i\sqrt{ 3} }{2} )~~~~~~

Multiplying them,

  • \displaystyle\frac{(2 +  i\sqrt{  3})\times(2 - i \sqrt{3})   }{2 \times 2}

  • \displaystyle\frac{(2 +  i\sqrt{  3})\times(2 - i \sqrt{3})   }{4}

Applying Distributive property,

  • \displaystyle\frac{2(2 +  i\sqrt{  3}) +  \: i \sqrt{3} (2 - i \sqrt{3})   }{4}

  • \cfrac{2 \times 2 + 2( - i \sqrt{3} ) + i \sqrt{3}(2 - i \sqrt{3} ) }{4}

  • \cfrac{2 \times 2 + 2( - i \sqrt{3}) + i \sqrt{3}   \times 2 + i \sqrt{3} ( - i \sqrt{3}) }{4}

Combining each terms,

  • \cfrac{4 - 2i \sqrt{3} + 2i \sqrt{3}   + 3}{4}
  • \cfrac{ - 2i \sqrt{3}  + 2i \sqrt{3} + 7 }{4}
  • \boxed{\cfrac{ 7}{4} }

Last Choice is accurate.

I really need help this is a matter or passing or failing and I am counting on you for help!
coldgirl [10]

Answer:

B

Step-by-step explanation:

In order for something to have infinite solutions, both sides need to be equal to each other.

Example:

3x + 7y = 7y + 3x

That has infinite solutions

3x + 7y = 7x + 3y

That is not equal to each other because the variables are different.

Hope I helped :)
