Given the definitions of f (x) and g(x) below, find the value of (gof)(-8).
f(x) = -x + 8
g(x) = x2 – 3x+2
Answer:
(gof)(-8) = 210
Step-by-step explanation:
(gof) = (-x + 8)² - 3(-x + 8) = 2
= x² - 16x + 64 + 3x - 24 + 2
= x² - 13x + 42
(gof)(-8) = (-8)² - 13(-8) + 42
= 64 + 104 + 42
= 210
Mrs. Lawton has a bank balance of $72 at the start of the month. On the 3rd of the month he withdrew $20. Then on the 8th, he withdrew 5 times the amount he withdrew on the 3rd.
1. What is Mrs. Lawton’s bank balance after the 2 withdrawals?
2. How much does Mrs. Lawton need to deposit into her account to give an exact balance of $200?
Answer:
1. Answer -48$
72-20 = 52
20 * 5 = 100
52 - 100= -48
2. 248$
-48 + 248 = 200

what is the area of the rectangle whose length is (x + 5) and width (x-5)
Answer:
area of the rectangle is length *breadth
length =(x+5)
breadth =(x-5)
=(x+5)(x-5)=x^2-5x+5x-25=x^2-25
Answer:
[tex]\boxed {\boxed {\sf a=x^2-25}}[/tex]
Step-by-step explanation:
The area of a rectangle is the product of length and width.
[tex]a=l*w[/tex]
The length is (x+5) and the width is (x-5).
[tex]a= (x+5)(x-5)[/tex]
We have two binominals, so we can multiply using FOIL: First, Outside, Inside, Last.
F: x*x= x²O: x*-5= -5x I: x*5= 5x L: 5*-5 = -25[tex]a= x^2-5x+5x-25[/tex]
Combine the like terms: -5x and 5x. They cancel each other out.
[tex]a=x^2-25[/tex]
The area of the rectangle is x²-25

The temperature at 12 am was 44 degrees. The temperature dropped steadily for the next 8 hours to reach the daytime low of 20 degrees. Create an equation for the relationship between temperature and the time.
Answer:
y=-3x+80
Step-by-step explanation:
Points (12,44) and (20,20)
slope = -3
Equation of line: y - 44 = -3(x - 12)
The equation for the relationship between temperature and time is
T = 44 - 3x
Where x is the number of hours and T is the temperature.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The temperature at 12 am = 44°
The temperature after 8 hours = 20°
Now,
The temperature drops steadily.
This means,
Temperature drops in an hour.
= (44 - 20) / 8
= 24/8
= 3°
The equation for the temperature after x hours.
= 44 - 3x
Thus,
The steady temperature drop in an hour is 3°.
