Simplify the expression. Write your answer as a power.<br><br> (−5/7)^8⋅(−5/7)^9
dem82 [27]

Answer: (-\frac{5}{7})^{17}

Step-by-step explanation:

The expression can be simplified by applying the a properties of exponents, specifically the Product of powers, which states that:

(b^a)(b^c)=b^{(a+c)

Where b is the base and a and c are exponents.

 Then simplify it by rewriting the base (-\frac{5}{7}) and adding the exponents of the expression (8 and 9).

You will get the expression simplified and written as a power:

(-\frac{5}{7})^8(-\frac{5}{7})^9=(-\frac{5}{7})^{(8+9)}=(-\frac{5}{7})^{17}

Andru [333]

Answer:

<h2>x = 0</h2>

Step-by-step explanation:

-8x-14=7(-2-4x)+4x\qquad\text{use the diastributive property}:\ a(b+c)=ab+ac\\\\-8x-14=(7)(-2)+(7)(-4x)+4x\\\\-8x-14=-14-28x+4x\qquad\text{add 14 to both sides}\\\\-8x-14+14=-14+14-24x\\\\-8x=-24x\qquad\text{add}\ 24x\ \text{to both sides}\\\\-8x+24x=-24x+24x\\\\16x=0\qquad\text{divdie btoh sides by 16}\\\\\dfrac{16x}{16}=\dfrac{0}{16}\\\\x=0
