Answer:
f(x) is another way of saying "y", but when x is replaced with a number, it just means that x = that number.
Since A says to find f(7), it means that in this scenario, x = 7. So, 2x - 5 is turned into 2(7) - 5, which equals 14 - 5, which equals 9.
So, f(7) = 9.
You can then apply this to the rest of the numbers you are given.
I hope this helps! :)

If you need more help I would love to help!
Answer:
18 eggs
Step-by-step explanation:
1: x/24=6/8
2: 24*6=144-(1st step for cross multiplication)
3: 144/8=18-(2nd step for cross multiplication)
4: 18 eggs-(final answer)
Cross multiplication: Write your 2(or more) equivilent fractions, and write your variable as x or any other letter. If your variable is in the numerator, take the denominator and multiply it with the other fraction's numerator and divide your answer with the denominator of the other fraction. If x is in the denominator, switch your variable with the other fractions numerator and solve the same way you would if the variable was in the numerator-(sorry if I made it to complex, but the idea is really simple:)

The number of students in a school fell from 700 last year to 646 this year. What is the percentage reduction?
Answers
Answer: 7.71%
Step-by-step explanation:
Number of students in a school last year = 700
Number of students in a school this year = 646
Reduction in the number of students = 700 - 646 = 54
The percentage reduction will be:
= Reduction in number / Last year students × 100
= (54 / 700) × 100
= 7.71%

Jason just got tired for a new job and will make $80,000 in his first year. Jason was
told that he can expect to get raises of $5,000 every year going forward. How much
money in salary would Jason make in his 23rd year working at this job?
Answers
Answer:
$110,080
Step-by-step explanation:
This is an arithmetic sequence because each new term is obtained by adding $5000 to the preivous term.
The general formula for such an arithmetic series is
a(n) = $80,000 + ($5,000)(n - 1)
and so in his 23rd year Jason would make
a(23) = $80,000 + ($5,000)(23 - 1), or
$110,080
Answer:
$110,080 is the answer
– x + 7 = 13

What is X
Answers
-x + 7 = 13, subtract 7 from both sides.
then you have -x = 6, and you have to device by negative 1 on both sides because you can’t have a negative x value. then you have x = -6.

The area of a rectangular field is 99m2. The length of one side is
11m. The farmer needs to know its perimeter to work out how
much fencing will be needed? Help
Answers
Answer:
40 m
Step-by-step explanation:
The length of another side
= 99÷11
= 9 m
The perimeter of the field
= 9×2 + 11×2
= 40 m
Answer:
40 m
Step-by-step explanation:
Hi there!
What we know:
The field is rectangularA = 99 m²Length of one side = 11 m1) Find the length of the other side
Plug all the given information into the area formula for a rectangle:
[tex]A=lw[/tex] where A is the area, l is the length and w is the width
[tex]99=11w[/tex]
Divide both sides by 11 to isolate w
[tex]\frac{99}{11} = \frac{11w}{11} \\9=w[/tex]
Therefore, the width of the field is 9 m.
2) Find the perimeter of the field
[tex]P=2(l+w)[/tex] where l is the length and w is the width
Plug in the length (11 m) and the width (9 m)
[tex]P=2(11+9)\\P=2(20)\\P=40[/tex]
Therefore, the perimeter of the field is 40 m.

Answer:
The length of the box is 6 cm. The width of the box is 3 cm. The height of the box is 2 cm.
Step-by-step explanation:
volume = length x width x height In this instance volume = 36 m³. I will let “b” be the length of the box. “w’ will be the width of the box. And “h” will be the height of the box. Therefore we know that b = 2w and b=3h. So: w= b /2 and h=b /3.
36 m³= b(b/2)(b/3)
36 = b³/6
b ³ = 216
b = 6
w = 6/2 = 3
h = 6/3 = 2

To shift h units to the right, replace x with x - h
To shift h units to the left, replace x with x + h.
To shift k units up, add k to the end of the formula for the function.
To shift k units down, subtract k from the end of the formula.
