Answers
Answer:
[tex]\textsf{C}\quad f^{-1}(x)=24-6x[/tex]
Step-by-step explanation:
You want the inverse function of f(x) = 24 -x/6.
Inverse functionThe function relates x to y by y = f(x). The inverse function gives the reverse relation: x = f(y). Solving this for y gives the inverse function in the form you want.
x = f(y)
x = 4 -y/6 . . . . . use definition of f(x)
6x = 24 -y . . . . multiply by 6
y = 24 -6x . . . . add y-6x
f⁻¹(x) = 24 -6x . . . . write using function notation

What does the answer tell you about home prices? HINT [See Example 2.]
The median price of a home was increasing at a rate of $ ___ per year in ____.
Answers
The value of P'(t) will be , P'(t) = -10t + 75 and value of P'(7) will be equal to 5 and rate of change of price will be $5 thousands per year in dollars.
It is given that median home price is represented by P(t) = -5t² + 75t - 30.
We have to find out the values of P'(t) and P'(7).
What is differentiation ?
Differentiation is a method in which the function's rate of change compared to the rate of change of the independent variable is calculated.
As per the question ;
The equation given is ;
P(t) = -5t² + 75t - 30
So ;
Differentiating the above equation with respect to t , we get ;
[tex]\frac{d}{dt}[/tex] (P(t)) = [tex]\frac{d}{dt}[/tex] ( -5t² + 75t - 30 )
[tex]\frac{d}{dt}[/tex] (P(t)) = P'(t) = -5 × 2 × t + 75
⇒ P'(t) = -10t + 75
And
The value of P'(7) will be ;
P'( t = 7) = -10 × 7 + 75
P'(7) = - 70 + 75
P'(7) = 5
Also ;
P(11) = 190
P(3) = 150
And
The rate of change of price will be ;
[tex]\frac{P(11) - P(3)}{11 - 3}[/tex]
= 190 - 150 / 8
= 40 / 8
= 5
Thus , the value of P'(t) will be , P'(t) = -10t + 75 and value of P'(7) will be equal to 5 and rate of change of price will be $5 thousands per year in dollars.

there are 18 walnuts, use a proportion and additional math to determine how
many cashews there are.
$2
3
Answers
The number of cashews in the can are 52.
Here, we are given that the ratio of walnuts to peanuts in a can of mixed nuts is 3 to 5.
⇒ walnuts : peanuts = 3 : 5
The number of walnuts in the packet are = 18
⇒ 18 : peanuts = 3 : 5
18/ peanuts = 3/5
peanuts = (5/3) × 18
peanuts = 30
Now, we know that the total number of nuts = 100
⇒ cashews + walnuts + peanuts = 100
cashews + 18 + 30 = 100
cashews + 48 = 100
cashews = 100 - 48
cashews = 52
Thus, the number of cashews in the can are 52.

The slope of the line AC is equal to the slope of the line CE.
We have the points:
A = ( - 3 , 6 )
C = ( - 1 , 3 )
Slope of AC will be:
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope of AC = m₁ = ( 3 - 6 ) / ( - 1 + 3 )
m₁ = - 3 / 2
m₁ = - 1.5
Now,
C = ( - 1 , 3 )
E = (3 , - 3)
Slope of AC = m₂ = ( - 3 - 3 ) / ( 3 + 1 )
m₂ = - 6 / 4
m₂ = - 3 / 2
m₂ = - 1.5
So, we get that:
m₁ = m₂
Therefore, we get that, the slope of the line AC is equal to the slope of the line CE.

The perimeter of a rectangular field is 356 yards. If the width of the field is 79 yards, what is its length?
Answers
356 - 158 = 198 yards
198/2 = 99 yards
Answer:
length = 99 yards
Step-by-step explanation:
the perimeter (P) of a rectangle is calculated as
P = 2(l + w) ← l is the length and w the width
given P = 356 and w = 79 , then
356 = 2(l + 79) ← divide both sides by 2
178 = l + 79 ( subtract 79 from both sides )
99 = l
the length of the field is 99 yards

LCM can help us to compare the two of the given fractions. The correct option is A, -(3/4) < -(5/16).
What is LCM?The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.
Bring both the terms to the same denominator for easy comparison. Now, since the LCM of 4 and 16 is 16. Therefore, we can write the two of the fractions as,
-(3/4) = -(3×4)/(4×4) = -12/16
-(5/16) = -5/16
Further, we can write the comparison of the two fractions as,
-12/16 < -5/16
-(3/4) < -(5/16)
Hence, the correct option is A, -(3/4) < -(5/16).
