Step 1: Define
g(x) = x² - 4
f(x) = -2x - 3
g(-6) is x = -6 for function g(x)
f(-6) is x = -6 for function f(x)
Step 2: Evaluate
g(-6)
Substitute in x: g(-6) = (-6)² - 4Exponents: g(-6) = 36 - 4Subtract: g(-6) = 32f(-6)
Substitute in x: f(-6) = -2(-6) - 3Multiply: f(-6) = 12 - 3Subtract: f(-6) = 9g(-6) - f(-6)
Substitute: 32 - 9Subtract: 239 + 4[(4 + 2)3 - (32 + 2)]

2. When 9 is added to the number that is produced by tripling the number x, the result is
equal to 6 times the number that is 3 less than x. Write an equation to represent the
situation and use it to find the value of x.
The equation that represents the situation is:
9 + 3x = 6(x - 3)
The value of x is x = 9
Word problem on linear equationLet the number be represented by x
Triple the number = 3x
9 added to the number that is produced by tripling the number x = 9 + 3x
3 less than x = x - 3
6 times the number that is 3 less than x = 6(x - 3)
Therefore, the equation that illustrates the situation is:
9 + 3x = 6(x - 3)
Solve for x in the equation above
9 + 3x = 6x - 18
6x - 3x = 9 + 18
3x = 27
Divide both sides by 3
3x/3 = 27/3
x = 9

Write 24 as a product of primes.
Use index notation when giving your answer.
Answer:
2^3 * 3
Step-by-step explanation:
Here are the first several prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23
To find the prime factorization of a number, start by dividing the number by the smallest prime number it is divisible by. Keep dividing by that prime number until you can't anymore. You only divide by prime numbers that divide evenly. Then move on to the next prime number that divides evenly, and do the same. You eventually will get to 1. Then you put together all the prime factors.
This is much easier to do than it sounds like in this explanation.
Start with 24.
24/2 = 12
12/2 = 6
6/2 = 3 3 is not divisible by 2, so we move on to 3.
3/3 = 1 We got to 1, so we are done.
The prime factorization is the product of all the prime numbers we divided by which are in bold.
24 = 2 * 2 * 2 * 3
Now we index it:
24 = 2^3 * 3

Garden soil costs $5.00 per a 2 cubic foot bag at lows. You have raised rectangular garden thag is 8 feet by 4 feet and you wish the depth of the soil to be 6 inches deep. How much will it cost to buy the bags of soul for your garden
Answer:
$40
Step-by-step explanation:
Step one:
given data
Garden soil costs $5.00 per a 2 cubic foot bag
dimension of rectangular garden raised
8 feet by 4 feet , depth is 6 in
6 in to feet= 0.5ft
the volume of the soil in the garden is
volume= 8*4*0.5= 16ft^3
Step two:
now if 2ft^3 cost $5
16ft^3 will cost x
cross multiply
x*2=16*5
divide both sides by 2
x= 16*5/2
x=80/2
x=$40

Daniel can paint a house in 10 days, while his father can paint the same house in 6 days. If they work together, how long will they finish the job? I need asap answer plssss
Answer:
3[tex]\frac{3}{4}[/tex] days
Step-by-step explanation:
Let the amount of work be x.
Daniel:
10 days = x
1 day = [tex]\frac{1}{10}[/tex]x
Father:
6 days = x
1 day = [tex]\frac{1}{6}[/tex]x
Together:
1 day = [tex]\frac{1}{10}[/tex]x + [tex]\frac{1}{6}[/tex]x
= [tex]\frac{6}{60}[/tex]x + [tex]\frac{10}{60}[/tex]x
= [tex]\frac{16}{60}[/tex]x
= [tex]\frac{4}{15}[/tex]x
No. of days = [tex]\frac{15}{15}[/tex]x ÷ [tex]\frac{4}{15}[/tex]x
= [tex]\frac{15}{15}[/tex]x × [tex]\frac{15}{4}[/tex]x

Answer:
y=2x−7
Step-by-step explanation:
so
formula is ( y 1 − y = m ( x 1 − x))
m is the slope
-1-y=2(3-x)
add 1 to both sides
−y−1+1=−2x+6+1
−y=−2x+7
divide both sides by -1
y=2x−7

The Video Club charges a $100 membership fee and then charges $5 per movie. The Movie Market has a $25 membership fee and then charges $10 per movie. When will both clubs have the same cost? What is the cost?
Answer:
At 15 movies, both will cost $175
Step-by-step explanation:
Set it up algebraicly. Let x be the number of movies
100 + 5x = 25 + 10x
75 + 5x = 10x
75 = 5x
x = 15
Lets substitute x into one equation
100 + 5(15)
100+75
175

The access code to a houses security system consists of 6 digits. How many different codes are available if each digit can be repeated? Please show work.
Answer:
1,000,000
Step-by-step explanation: Since there are 10 possible digits, we know that there is a 1/10 chance for any possible digit in any slot. So, since there are 6 slots we can do 1/10^6, or 1 in 1 million.
So, 720 ways are available if each digit can be repeated

CJ wants a new video game but is not sure which one to buy. His choices are 5 sports games, 3 role-playing games, and 8 action games. He writes the game titles on pieces of paper and puts them all in a bag. He wants to buy two different games. If he randomly selects two names from the bag, what is the probability that CJ selects two sports games?
Answer:
1 /12
Step-by-step explanation:
Given that:
Number of sports game = 5
Role playing games = 3
Action games = 8
Total = (5 + 3 + 8) = 16
The probability of selecting two sports game from the bag :
First selection = sport game and second selection will also be a sport game.
This scenario with be a selection without replacement pattern
First selection :
Number of sports game / total number of options
5 / 16
SEcond selection : total left = 16 - 1 = 15 ; number of sports game = 5 - 1 = 4
Hence
P(sports on second selection) = 4 / 15
P(sports on first and second) :
5/ 16 * 4/15 = 20/ 240 = 1 / 12
