None of the answers listed are correct.

3x + 11 = k

SUBTRACT 11 from both sides:

3x + 11 = k

-11 -11

You are then left with:

3x = k-11

DIVIDE 3 by both sides:

3x/3 = k-11/3

You are then left with:

x= k-11/3

Use the following steps to prove that log b(xy)- log bx+ log by.

borishaifa [10]

Answer with Step-by-step explanation:

a. $x=b^p$

$y=b^q$

Taking both sides log

$log x=plog b$

Using identity: $logx^y=ylogx$

$p=\frac{logx}{log b}=log_b x$

Using identity: $log_x y=\frac{log y}{log x}$

$log y=qlog b$

$q=\frac{log y}{log b}=log_b y$

b. $xy=b^pb^q$

We know that

$x^a\cdot x^b=x^{a+b}$

Using identity

$xy=b^{p+q}$

c. $log_b(xy)=log_b(b^{p+q})$

$log_b(xy)=(p+q)log_b b$

Substitute the values then we get

$log_b(xy)=(log_b x+log_b y)$

By using $log_b b=1$

Hence, $log_b(xy)=log_b x+log_b y$

Someone answer this please

butalik [34]

Answer:

no, all of the parts aren't even.

Step-by-step explanation:

the parts must be even to make a fraction so it could also be said as out of 8 equal parts, 3 are shaded but the parts arent equal so you can't.

Hope this helps! :)

Answer:

2x+20 + x+40 = 180

Step-by-step explanation:

Plz HELP! WILL GIVE BRAINLIEST!<br><br>1. Consider the picture below. Find the measure of ∠CEA.

pashok25 [27]

Answer:

103°

Step-by-step explanation:

The marked angles have the same measure, so ...

14x+7 = 12x +17

2x = 10 . . . . . subtract 12x+7

x = 5 . . . . . . . divide by 2

(14x +7)° = 77°

∠CEA is supplementary to the marked angles:

∠CEA = 180° -77°

∠CEA = 103°
