Answer:

(1.5, 10.5)

Step-by-step explanation:

$midpoint = \bigg( \frac{10 + ( - 7)}{2}, \: \: \frac{14 + 7}{2} \bigg) \\ \\ = \bigg( \frac{3}{2}, \: \: \frac{21}{2} \bigg) \\ \\ = = ( 1.5, \: \: 10.5 )$

Factor the expression:

Dovator [93]

Answer:

B) (4x-5i)(4x+5i)

Step-by-step explanation:

The expression can be treated as the difference of squares, and factored accordingly. That factoring is ...

a² -b² = (a -b)(a +b)

Here, we have ...

a² -b² = 16x² -(-25)

a² = 16x² ⇒ a = 4x

b² = -25 ⇒ b = √-25 = 5i

Then the factoring is ...

(a -b)(a +b) = (4x -5i)(4x +5i)

How can I solve for the logarithm?

Sergio039 [100]

$\bf 12^{2x-8}=15\\\\
-----------------------------\\\\
log_{{ a}}\left( x^{{ b}} \right)\implies {{ b}}\cdot log_{{ a}}(x)\impliedby thus\\\\
-----------------------------\\\\
log\left( 12^{2x-8} \right)=log(15)\implies (2x-8)log(12)=log(15)
\\\\\\
2x-8=\cfrac{log(15)}{log(12)}\implies 2x=\cfrac{log(15)}{log(12)}+8\implies 
x=\cfrac{\frac{log(15)}{log(12)}+8}{2}$
