Answer:

$\boxed{\sf{b=2}}$

Step-by-step explanation:

Isolate the b from one side of the equation.

First, subtract by 5 from both sides.

$\sf{5+2b-5=9-5}$

Solve.

Subtract.

9-5=4

2b=4

Divide by 2 from both sides.

2b/2=4/2

Solve.

Divide the numbers from left to right.

4/2=2

$\Longrightarrow \boxed{\sf{b=2}}$

Therefore, the correct answer is b=2.

I hope this helps, let me know if you have any questions.

Can someone also explain how to get the answer thank u

Answer:

$m = -\frac{194}{3}$

Step-by-step explanation:

I'm assuming you are trying to find m. In order to do so, you need to get m on one side.

Before doing that let's multiple -2 and -3m by $\frac{4}{3}$

$256=-\frac{8}{3} - 4m$

add $-\frac{8}{3}$ to both sides

$258\frac{2}{3}=-4m$

I would get rid of the fraction so I'd multiply both sides by $\frac{3}{1}$

$\frac{776}{3}*3 = 4m*3$

$776=-12m$

divide both sides by -12m

$m = -\frac{776}{12}$

which can be simplified to

$m = -\frac{194}{3}$

ALL UNLESS THAT $\frac{4}{3}$ IS A POWER

Jean estimates that her friend completes a new level of a video game on the first try 20% of the time. She conducts a simulation

Rainbow [258]

The probability of the friend completing the new level in her first try is 22.5%

<h3>What is probability?</h3>

This is a concept that is used to talk about the likelihood or the chances of an event occuring.

For the digit 8, the frequency is 7

For the digit 9, the frequency is 11

The total number of frequencies is given as

10 + 9 + 6+ 7 + 8 + 12 + 4 + 6 + 7 + 11 = 80

7 + 11 = 18

Probability = 18/80

= 0.225 x 100

= 22.5%

Write the equation for an absolute value function with the following transformations:

Kipish [7]

Answer:

j(x) = 5 |x+9|-23

Step-by-step explanation:

f(x) = |x|

translate left 9 units

y = f(x + C) C > 0 moves it left

g(x) = |x+9|

translate down 23 units

y = f(x) + C C < 0 moves it down

h(x)= |x+9|-23

stretch by a factor of 5

y = Cf(x) C > 1 stretches it in the y-direction

j(x) = 5 |x+9|-23
