Answer:
-2.4
Step-by-step explanation:
-54/22.5= -2.4
If it went down 54 degrees in 22.5 minutes, then you do -54/22.5, which gives you -2.4. So the temperature went down 2.4 F each minute. I think.

2. What is the equation of the line that passes through the points (4,5) and
(8,3)?
Answer:
y = -1/2x + 7
Step-by-step explanation:
The slope is -1/2.
The y intercept is 7.
Plugging them into the format for the equation we have:
y = mx + b
(m = slope and b = y intercept)
y = -1/2x + 7

Consider a function f(x) such that f(5x) =x-5/5x-1. Find f(x) and hence write down the domain of f(x).
Answer:
[tex]f(x) = \frac{x - 25}{5x - 5}[/tex]
Domain: [tex]x \ne 1[/tex]
Step-by-step explanation:
Given
[tex]f(5x) = \frac{x - 5}{5x - 1}[/tex]
Required
Determine f(x) and its domain
To determine f(x), we replace 5x with x in f(5x)
So, we have:
[tex]f(5x) = \frac{\frac{5x}{5} - 5}{5x - 1}[/tex]
[tex]f(x) = \frac{\frac{x}{5} - 5}{x - 1}[/tex]
Take LCM
[tex]f(x) = \frac{\frac{x - 25}{5}}{x - 1}[/tex]
[tex]f(x) = \frac{x - 25}{5} * \frac{1}{x-1}[/tex]
[tex]f(x) = \frac{x - 25}{5x - 5}[/tex]
To get the domain, we set the denominator as
[tex]5x - 5 \ne 0[/tex]
[tex]5x \ne 5[/tex]
[tex]x \ne 1[/tex]

Step-by-step explanation:
6 x - 2 (x - 5) = 22
Answer:
x = 2.75
Step-by-step explanation:
6x - 2 (x - 5) = 22
6x -2x + 10 = 22
4x + 10 = 22
- 10 - 10
4x = 11
11/4 = 2.75
x = 2.75

if x+1/x = 5 find the value of x^3 +1/x^3. pls solve
Answer:
1) solve x+1/x = 5
[tex] \frac{x + 1}{x} = 5[/tex]
[tex]x + 1 = 5x[/tex]
[tex]x - 5x = - 1[/tex]
[tex] - 4x = - 1[/tex]
[tex]x = \frac{ -1}{ - 4} [/tex]
[tex]x = \frac{1}{4} [/tex]
2) solve x³+1/x³
[tex]x {}^{3} + \frac{1}{x {}^{3} } [/tex]
substitute x = 1/4 into the expression
[tex]( \frac{1}{4} ) {}^{3} + \frac{1}{( \frac{1}{4}) {}^{3} } [/tex]
[tex] \frac{1}{64} + \frac{1}{ \frac{1}{64} } [/tex]
[tex] \frac{1}{64} + \frac{64 \times 1}{1} [/tex]
[tex] \frac{1}{64} + 64[/tex]
[tex] \frac{4097}{64} \: or \: 64.02[/tex]

PPLLSS AANNDD TTHHXX!!
How to solve your question
Solve for y:
-y = 3 y
Subtract 3 y from both sides:
-y - 3 y = 3 y - 3 y
-y - 3 y = -4 y:
-4 y = 3 y - 3 y
3 y - 3 y = 0:
-4 y = 0
Divide both sides of -4 y = 0 by -4:
(-4 y)/(-4) = 0/(-4)
(-4)/(-4) = 1:
y = 0/(-4)
0/(-4) = 0:
Answer: | y = 0
