♡ The Question ♡      

・3 (x + 4) = x - 8 - 2x

* ♡ The Answer ♡      

・x = -5

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*      

♡ The Explanation/Step-By-Step ♡      

・3 (x + 4) = x - 8 - 2x

3 (x + 4) = x - 2x - 8

3 (x + 4) = -x - 8

3 (x + 4): 3x + 12

Apply the distributive law! : a(b + c) = ab + ac

a = 3, b = x, c = 4

= 3x + 3 x 4

Multiply: 3 x 4 = 12

= 3x + 12

3x + 12 = -x - 8

Subtract 12 from both sides!

3x + 12 - 12 = -x - 8 - 12

Simplify!

3x = -x - 20

Add x to both sides!

3x + x = -x - 20 + x

Simplify!

4x/4 = -20/4

Simplify 4x/4 : x

Divide the numbers!

4/4 = 1 = x

Simplify!

-20/4 : -5

-20/4

Apply the fraction rule! : -a/b = -a/b

= -20/4

Divide the numbers!

20/4 = 5

= -5

x = -5

Hey can you please help me posted picture of question
mote1985 [20]
Two events are occurring:

1) Rolling a die
Sample Space = {1,2,3,4,5,6}
Total number of outcomes in sample space = 6
Favorable outcomes = Odd number
Number of Favorable outcomes = 3

Probability of getting an odd number = 3/6 

2) Tossing a coin
Sample Space = {H, T}
Probability of getting a head= 1/2

The probability of getting odd number and head will be the product of two probabilities, which will be = 3/6 x 1/2 = 3/12 

Thus there is 3/12 = 1/4 (0.25 or 25%) probability of getting an odd number and a head in given scenario. 

So correct answer is option C

Given the parent function f(x) = 2^x, which graph shows f(x) + 1?
mixer [17]

Answer: First Option

a) exponential function going through point (0, 2) and ending up on the right

Step-by-step explanation:

Look at the attached image, the red line represents a function of the form:

f(x) = 2^x

Note that this function cuts to the axis and at the point (0, 1)

Also when x tends to ∞ f(x) tends to ∞ and when f(x) tends to -∞ then f(x) tends to zero.

If we perform the transformation y = f(x) +1 then the graph of y is equal to the graph of f(x) displaced 1 unit up. Then the new cutting point with the axis y will be: (0, 2) as shown in the attached image (blue line)

The transform function is y =2^x +1

Finally the answer is the first option
