Step-by-step explanation:
-2(x + 10) + 4 = -32
-2(x + 10) = -32 -4
-2(x + 10) = - 36
x + 10 = (-36)/(-2)
x + 10 = 18
x = 18 - 10
x = 8

he inverse of F(C) = 9 5 C + 32 is C(F) = F −
Answer:
C(F) = 5/9 F − 160/9
Step-by-step explanation:
[tex]f(c) = \frac{5}{9} (c-32)[/tex] will be the required inverse function of f(c).
The given function is:
[tex]f(c) = \frac{9}{5} c +32[/tex]
What is the inverse of a function?If there is a function f(x), then a function g(x) is called the inverse of the function if f(x) is a bijective function and the domain of f(x) should be equal to the range of g(x) while the range of f(x) should be equal to the domain of g(x).
[tex]f(c) = \frac{9}{5} c +32[/tex],
let us suppose [tex]y= \frac{9}{5} c +32[/tex]
[tex]y-32 = \frac{9}{5} c[/tex]
[tex]c = \frac{5}{9} (y-32)[/tex]
[tex]c = \frac{5}{9} (f(c)-32)[/tex]
In order to get the inverse function, interchange c and f(c),
[tex]f(c) = \frac{5}{9} (c-32)[/tex]
Therefore, [tex]f(c) = \frac{5}{9} (c-32)[/tex] will be the required inverse function of f(c).

In order to win a jar of candy you must guess how many pieces are in a jar within 30. If there are a total of 500 pieces of candy in the jar, what are the maximum and minimum amounts you could guess in order to win?
Answer:
530, 470.
Step-by-step explanation:
The maximum amount is 500 + 30 = 530.
The minimum amount is 500 - 30 = 470.

What are the x- and y-coordinates of point C, which partitions the directed line segment from A to B into the ratio 5:8? Round to the nearest tenth, if necessary. (–2.2, –6.3) (–2.4, –6.4) (2.7, –0.7) (1.2, –4.7)
Answer:
(1.2, –4.7)
Step-by-step explanation:
Since in the question it is mentioned that on the plane of coordinate, a line is made from point A (7,-2) to point B(-8,-9)
Also, the ratio of A to B is 5:8
Based on this, the x and y coordinates at point C is
[tex]= [\frac{5\times (-8) + 8\times 7}{5 + 8} , \frac{5\times (-9) + 8\times -2}{5 + 8}]\\\\= [\frac{16}{3}, \frac{-61}{13}][/tex]
= (1.2, –4.7)
Hence, the x and y coordinates of point C is (1.2, –4.7)
Therefore the last option is correct

Clint and Jim rode their bicycles to Mill Park at an average of 8 mi/hr. It took then 1 hr longer to return home riding at an average of 7 mi/hr on a route that was 4 mi longer than their route. How long were they riding their bicycles? How man miles did they ride each way?
Answer:
Total time for which they ride = [tex]\bold{7\ hours}[/tex]
Number of miles they ride each way = 24 mi
Step-by-step explanation:
Average speed = 8 mi/hr
Let the Distance to Mill Park = [tex]D[/tex] mi
Let the time taken = [tex]t[/tex] hours
Formula:
[tex]Distance = Speed \times Time[/tex]
[tex]\Rightarrow D = 8t[/tex] ..... (1)
Now, when average speed = 7 mi/hr
Time taken is 1 hour more, i.e. Time = [tex]t+1[/tex] hours
Distance traveled is 4 mi more, i.e. [tex]D+4[/tex] mi
Using the Formula:
[tex]Distance = Speed \times Time[/tex]
[tex]D+4=7\times (t+1)[/tex]
From equation (1):
[tex]8t+4=7t+7\\\Rightarrow t=3\ hours[/tex]
From equation (1):
[tex]D = 8 \times 3 = 24\ mi[/tex]
Total time for which they ride = [tex]t+t+1 = \bold{7\ hours}[/tex]
Number of miles they ride each way = 24 mi

Step-by-step explanation:
s + 3s = 4st + 3t = 4tIf 4s is 2 more than 4t, then:
4s = 2+ 4t4s - 4t = 24s/4 - 4t/4 = 2/4s - t = 1/2(C) is the answer
Answer:
C
Step-by-step explanation:
We are given
t + 3t + 2 = s + 3s, that is
4t + 2 = 4s ( subtract 4t from both sides )
2 = 4s - 4t ← factor out 4 from each term
2 = 4(s - t) ← divide both sides by 4 , thus
s - t = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex] → C

There were 73 runners from 2 schools on a combined track team. If 31 were
from Edison Elementary, how many were from Lincoln Elementary? Write and
solve an algebraic equation.
Answer:
s=(73-31)
31+s=73
s= 42
Step-by-step explanation:
In order to get an exact count of the Lincoln Elementary students you just have to subtract 31 from 73 to get 42 students. Therefore we get s to represent the Lincoln students, so the equation would be 31+s=73.
Find g(f(x)) when f(x) = 3x2 + x - 8, and g(x) = 4x + 5.
Answer: 12x^3 + 19x^2 -27x -40
Step-by-step explanation:
Finding f(x) times g(x) is multiply the two polynomials
(4x+5)(3x^2 + 1x -8) Apply the distributive property twice to solve
4x ( 3x^2 + 1x -8)
12x^3 + 4x^2 - 32x
5(3x^2 + 1x -8)
15x^2 + 5x - 40
12x^3 + 4x^2 - 32x + 15x^2 + 5x -40 now combine like terms
12x^3 + 19x^2 -27x -40
The function g(f(x)) will be written as g(f(x)) = 12x² + 4x - 27.
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The functions are given below.
f(x) = 3x² + x - 8 and g(x) = 4x + 5
The function g(f(x)) is written as,
g(f(x)) = 4(3x² + x - 8) + 5
Simplify the function, then we have
g(f(x)) = 4(3x² + x - 8) + 5
g(f(x)) = 12x² + 4x - 32 + 5
g(f(x)) = 12x² + 4x - 27
The capability g(f(x)) will be composed as g(f(x)) = 12x² + 4x - 27.
