Answer:
g(f(x)) = 9x² + 15x + 4
Step-by-step explanation:
Given :
⇒ f(x) = 3x + 4
⇒ g(x) = x² - 3x
=============================================================
Solving :
⇒ g(f(x))
⇒ g(3x + 4) = (3x + 4)² - 3(3x + 4)
⇒ g(3x + 4) = (3x)² + 2(3x)(4) + (4)² - 9x - 12
⇒ g(3x + 4) = 9x² + 24x + 16 - 9x - 12
⇒ g(f(x)) = 9x² + 15x + 4

Question 4 options:
2x+8=11
2x−8=11
2(x−8)=11
2(x+8)=11
Answer:
2x+8=11
Step-by-step explanation:
The equation 2x + 8 = 11 would be the answer.
2 (coefficient) ----> it would multiply by the unknown value represented by the common variable "x".
Because in the given situation, it says twice (means 2 multiplied by a number or a number multiplied twice by itself) then multiplication would be the order of operation used between the 2 and x.
The "and" indicates the order of operation addition, as it is proven as the only given options for the answer all equal 11.
Therefore, proving that option A is the answer.

Do you think it would be better to purchase whole onions at $1.99 per pound, and cut them yourself, or purchase pre-sliced onions at $2.99 per pound? Explain your rationale using a cost and portion argument
The best option is to purchase the onion at $1.99.
What is the cost?The cost of any item is defined as the amount paid by the consumer to the seller in the replacement of the item.
Here, the cost of whole onions at $1.99 per pound, cut them yourself, and purchase pre-sliced onions at $2.99 per pound.
The loss = $2.99 - $1.99 = $1
You are giving more amount by $1 for the same onion cutting the onion is not a big task you can cut whole onions with a knife in no time.
Hence, purchase onions at $1.99 to save $1.

Answer:
A. p=0.42n
Step-by-step explanation:
2.52/6 = $0.42
$0.42 = the cost of one oranges
So,
To find the cost of n oranges you need to multiply it by 0.42
P=0.42 x n
Ex. Find the price of 4 oranges
So you're going to multiply 4 by 0.42 to get the cost of 4 oranges that will equals $1.68
The answer is p=0.42n
Gavin is selling water bottles at a baseball game to help raise money for new uniforms. Before the game, he buys 48 water bottles for a total of $18.50. At the game, he sells all of the bottles for $1.25 each. How much profit does Gavin make?
Step-by-step explanation:
he buys 48 bottles for $18.50.
FYI : that means he gets them for
18.5/48 = $0.385416666... per bottle
he sells all 48 bottles for $1.25 per bottle.
that means the revenue (or selling income) is
48 × 1.25 = $60.00
profit is now income minus basic costs :
profit = 60 - 18.5 = $41.50
A two-digit number is reduced by 45 when the digits are interchanged. The digit in the tens pace
of the original number is 1 more than 3 times the digit in the units place. Define variables and
write a system of equations to find the original number.
The system of equations to find the original number is;a = 3b +1 and (10a + b) - (10b +a) = 45
What is the system of equations to find the original number?From the task content;
let the number in the tens place of the original number be a and the number in the units place be b.Hence, the required system of equations is;
a = 3b(10a + b) - (10b +a) = 45On this note, the required numbers can be evaluated from the equations above;

Question 14 Write the equation of the reaches a slope of point-slope form.
Answer:
y = 3x - 1 .
Step-by-step explanation:
The general point-slope form is y = mx + c where m = slope and c is the y-intercept
As we are given the slope and one point we first use the point-slope form:
y - y1 = m(x - x1)
y - 5 = 3(x - 2)
y = 3x - 6 + 5
y = 3x - 1 (Answer).
