Answer:

<h2>B. There are no zeros</h2>

Step-by-step explanation:

\text{The zeros for y = 0:}

x^2+4x+5=0\qquad\text{subtract 5 from both sides}\\\\x^2+2(x)(2)=-5\qquad\text{add}\ 2^2\ \text{to both sides}\\\\x^2+2(x)(2)+2^2=-5+2^2\qquad\text{use}\ (a+b)^2=a^2+2ab+b^2\\\\(x+2)^2=-5+4\\\\(x+2)^2=-1

Answer:

B. There are no zeros

Step-by-step Explanation:

None of the given point even lie on the parabola (curved line) of the graph, so they can't possibly be zeros. The only explanation is that there simply aren't any zeros.

So your answer is...B. There are no zeros.

Hope this helps!

What is the Properties of Equality
Vesna [10]

Hi there,

Properties of Equality is two equations that have the same solution which are called equivalent equations. For example: 5+3=2+6 which all equal to 8.

In geometry, properties of Equality are the reflexive (2x=2x, a=a, b+1=b+1), symmetric (2a=3b then 3b=2a) and transitive property (if a+1=3 and 3=1-b, then a+1=1-b)

Hope this helped :)

Have a great day

What is the base 8 representation of the number 11100111(2)
kondor19780726 [428]

Remark

You could convert base two to base 10 and then convert base 10 to base 8. That's the long way. The procedure below is the short way.

Step One

Write the base 2 number in groups of 3 starting from the right and going left

11 100 111

Step Two

Convert the base 2 numbers in groups of 3 to base 8. The largest result will be a 7

11 = 2*1 + 1 = 2 + 1 = 3

100 = 1*2^2 = 4

111 = 1*2^2 + 1*2 + 1 = 7

Step Three

Read the answer going down.

347 is the answer

Answer

347(8) = C
