The answer is: 1/64

The only advice I can give you when solving such problems is to memorize your exponent rules.


The exponent rules I used to solve this problem was the quotients rule and the negative exponents rule.


Quotients rule: x^m/x^n= x^m-n

Negative Exponents rule: x^-n= 1/x^n

Kisachek [45]

Answer:

c

Step-by-step explanation:

<em>To </em><em>find </em><em>the </em><em>midpoint</em><em> </em><em>the </em><em>formulas</em>

<em>x=</em><em>x1+</em><em>x2/</em><em>2</em><em> </em><em>and </em><em>y</em><em>=</em><em>y1+</em><em>y2/</em><em>2</em><em> </em><em>are </em><em>used </em>

<em>in </em><em>this </em><em>case </em><em>x1 </em><em>is </em><em>5</em><em>,</em><em>x2 </em><em>is </em><em>5</em><em>,</em><em>y1 </em><em>is </em><em>4</em><em> </em><em>and </em><em>y2 </em><em>is </em><em>-</em><em>3</em>

<em>therefore</em>

<em>x=</em><em>5</em><em>+</em><em>5</em><em>/</em><em>2</em><em>. </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em>

<em> </em><em> </em><em>=</em><em>1</em><em>0</em><em>/</em><em>2</em>

<em> </em><em> </em><em>=</em><em>5</em>

<em>y=</em><em>4</em><em>+</em><em>(</em><em>-</em><em>3</em><em>)</em><em>/</em><em>2</em>

<em> </em><em> </em><em>=</em><em>1</em><em>/</em><em>2</em>

HELP PLEASE 50 POINTS!!!! PLZ DON'T GUESS!
Olin [163]

Hey DatGamer13!

Question:

Solve for x

Solution:

Subtract 10 from both sides.

3x^2 + 13x − 10 = 10 − 10

3x^2 + 13x − 10 = 0

Factor left side of equation.

(3x − 2) (x + 5) = 0

Set factors equal to 0.

3x − 2 = 0 or x + 5 = 0

Answer:

x = 2/3 or x = −5
