Answer:
x = no.of months
y = cost
f(12) = 30x+75
f(12) = 30(12)+75
f(12) = 360+75
f(12) = 435
Therefore it cost him $435 in 12 months.
It will cost him $435 in 12 months or the value of f(12) is $435.
It is given that cost of gym membership is $75 plus $30 per month and the equation representing it is y = 30x + 75.
We have to find the value of f(12) or cost of gym after 12 months.
What do you mean by domain and ranges of a function ?
The domain is set of all values for which the function is defined and the range of the function is set of all values that function takes.
As per the question ;
The cost of gym membership is $75 plus $30 per month.
and
The given equation is ;
y = 30 x + 75
where ;
x = no. of months
and
y = cost
So , we can find out the value of f(12) as ; y = f(x) = f(12)
⇒ f(12) = 30x + 75
⇒ f(12) =( 30 × 12 ) + 75
⇒ f(12) = 360 + 75
⇒ f(12) = 435
Thus , it will cost him $435 in 12 months or the value of f(12) is $435.

2.4x + 4.6x = 28 Could someone help me with this problem I need it.
Answer:
x = 4
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define
2.4x + 4.6x = 28
Step 2: Solve for x
Combine like terms (x): 7x = 28Divide 7 on both sides: x = 4Step 3: Check
Plug in x to verify it's a solution.
Substitute in x: 2.4(4) + 4.6(4) = 28Multiply: 9.6+ 18.4= 28Add: 28 = 28Here we see that 28 does indeed equal 28.
∴ x = 4 is a solution of the equation.

Find QR
QR + RS = QS
18 + x + 2x + 24 = 17
Answer:
QR = 10
Step-by-step explanation:
QR + RS = QS , substitute values
18 + x + 2x + 23 = 17 , that is
3x + 41 = 17 ( subtract 41 from both sides )
3x = - 24 ( divide both sides by 3 )
x = - 8
Thus
QR = 18 + x = 18 - 8 = 10

David estimated that the band fundraiser would make $492.
The fundraiser actually made $600. What was the percent
error of David's estimate?
Answer:
18%
Step-by-step explanation:
if i am right
it would be subtract 492- 600 = -108
make this a positive value so 108
and divide it by the actual made amount
108/600 which would be 0.18 multiply this by 100 and you have 18% !!

Kiran has LaTeX: 10\frac{1}{2} 10 1 2 feet of lumber and wants to make a bookshelf. Kiran needs two side panels that are each LaTeX: 5\frac{2}{3} 5 2 3 feet. How much more lumber does Kiran need in order to make the side panels? A) LaTeX: \frac{5}{6} 5 6 feet B) LaTeX: \frac{1}{2} 1 2 feet C) LaTeX: 1\frac{5}{6} 1 5 6 feet D) LaTeX: 1\frac{1}{2} 1 1 2 feet
Answer:
A) LaTeX: \frac{5}{6} 5 6 feet
Step-by-step explanation:
Kiran has 10 1/2 feet of lumber and wants to make a bookshelf.
Kiran needs two side panels that are each 5 2/3 feet.
1 side panel = 5 2/3 feet
2 side panels =
2 × 5 2/3
2 × 17/3
= 34/3
= 11 1/3 feet
Kiran would need 11 1/3 feet of lumber.
Kiran already has 10 1/2 feet
How much more lumber does Kiran need in order to make the side panels?
This is calculated as:
11 1/3 - 10 1/2
11 - 10 + (1/3 - 1/2)
1 + ( 2 - 3/6)
1 + (-1/6)
1 - 1/6
= 5/6
Hence, Kiran need 5/6 feet more of Lumber.

What is the value of both these problems?
Problem 2
We have an isosceles triangle because of the two congruent sides (21 each).
The angles opposite the congruent sides are known as the base angles, and the base angles are congruent. For now, we don't know what they are. They are both x. I recommend writing 'x' onto the diagram where that missing unmarked angle is.
Then we'll use the idea that all three angles of any triangle always add to 180
x+x+38 = 180
2x+38 = 180
2x = 180-38
2x = 142
x = 142/2
x = 71
Answer: Choice A) 71=======================================================
Problem 3
We use the same ideas as the previous problem. This time the base angles are 56 degrees each. The remaining angle is x.
x+56+56 = 180
x+112 = 180
x = 180-112
x = 68

b) How many games, in total, are played

Answer:
Step-by-step explanation:210 games
14+13+12... (x2)
The total number of games played is 182.
What is permutation?The number of possible arrangements for a given set is calculated mathematically using permutation, where the arrangement's order matters.
Given that, there are 14 teams and each team plays twice with the other team.
Since each team plays every other team twice, the total number of games is nothing but the permutation of 2 out of 14 which is given by:
₁₄P₂
=14!/((14-2)!)
= (14×13×12!)/ 12!
= 14×13
=182
Hence, the total number of games played is 182.
