What is the inverse of the function f(x)=-4x+2
Answer:
The inverse of f is [tex]f^{-1}[/tex] = (x -2)/4
Step-by-step explanation:
To find the inverse of f(x) = 4x + 2 , interchange the variables and solve for y.
Rewrite f(x) = 4x + 2 as x = 4y + 2 then solve for y
x -2 = 4y
(x - 2)/4 = y

Jason has a starting salary of 9.25 per hour .Jason’s manager informs him that if he meets his self quota each month he can expect annual pay rate increase of 0.90 write an equation representing the relationship between the years on the job y and pay per hour p
Answer:
Assuming the "pay increase" is $/hr: p = 9.25 + 0.90y
Step-by-step explanation:
p = 9.25 + 0.90y : The 9.25 is for year (y)=0[the starting hourly wage]. 0.90 is added each year, starting with y=1. Each addirtional year add one more 0.90 to his starting wage.

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 70 pounds. The truck is transporting
50 large boxes and 70 small boxes. If the truck is carrying a total of 4100 pounds in boxes, how much does each type of box weigh?
Answers:
one small box = 30 pounds
one large box = 40 pounds
==========================================================
Work Shown:
S = weight of one small boxL = weight of one large boxS+L = 70 since the two boxes combine to 70 pounds.
70S = weight of 70 small boxes
50L = weight of 50 large boxes
70S+50L = weight of 70 small and 50 large
70S+50L = 4100
The system of equations is
[tex]\begin{cases}S+L = 70\\70S+50L = 4100\end{cases}[/tex]
There are a few ways to solve this system. I'll use substitution.
I'm going to isolate L in the first equation like so
S+L = 70
L = 70-S
Which I'll then plug into the other equation to solve for S
70S+50L = 4100
70S+50(70-S) = 4100
70S+3500-50S = 4100
20S+3500 = 4100
20S = 4100-3500
20S = 600
S = 600/20
S = 30
Each small box is 30 pounds.
Use this value of S to find L
L = 70-S
L = 70-30
L = 40
Each large box is 40 pounds.
Like we expect, each large box weighs more compared to any given small box.
------------------
Check:
S+L = 30+40 = 70 verifies the first equation70S+50L = 70*30+50*40 = 4100 verifies the second equationBoth equations are true for the ordered pair (S,L) = (30,40). Therefore, the answers have been confirmed.

if f(x)=2x-3 find f(7)
Answer:
f(7) = 11
Step-by-step explanation:
Given the linear function, f(x) = 2x - 3:
In order to find the value of f(7), simply substitute the value of the input, x = 7 into the function:
f(x) = 2x - 3
f(7) = 2(7) - 3
f(7) = 14 - 3
f(7) = 11
Therefore, the value of f(x) when x = 7 is:
f(7) = 11.If 18.2 is 100% then what is 1.7

In the given figure, m ǁ n, then the value of y is:
(a) 70°
(b) 35°
(c) 60°
(d) 40°
Answer:
(b) 35°Step-by-step explanation:
x + 60° = 180° ( interior angles )
[tex]x + {60}^{o} = {180}^{o} \\ x = {180}^{o} - {60}^{o} \\ x = {120}^{o} \\ [/tex]
x = z ( opposite angles )
z = 120°
y + 25° + 120° = 180°
(The sum of all interior angles of any triangle is equal to 180°)
[tex]y + {25}^{o} + {120}^{o} = {180}^{o} \\ y + {145}^{o} = {180}^{o} \\ y = {180}^{o} - {145}^{o} \\ y = {35}^{o} \\ [/tex]
The value of y in the given figure is (b) 35°
Since m||n, hence:
a + 60 = 180 (sum of consecutive interior angles formed by two parallel lines are supplementary)
a + 60 = 180
a = 120°
a = b (vertical opposite angles are congruent to each other)
120 = b
b = 120°
y + 25 + b = 180 (sum of angles in a triangle)
y + 25 + 120 = 180
y + 145 = 180
y = 35°
Hence the value of y is (b) 35°

Divide 320 into 8 equal groups
Answer:
320 divided by 8 is 40. 40 times 8 is 320, so it works backwards.
When dividing 320 into 8 equal groups, each group would contain 40.
We have to divide 320 into 8 equal groups.
Performing the division as
8 | 320 | 40

One angle of an isosceles triangle measures 140°. Which other angles could be in that isosceles triangle? 80° 20° 50° 40° plzzzzzzzzz help me
Answer:
20°
Step-by-step explanation:
If it's an isosceles triangle, the two remaining angles should be equal. (Angles opposite to equal sides are equal)
∴ one remaining angle = (180° - 140°)/2
= 40° / 2
= 20°

fatima claims that the distribution of u is uniform with a median of 0.4 field goal percentage. is fatima’s claim supported by the table?
Fatima's claim is not supported by the table because, the distribution is skewed right, with a median of 0.4 field goal advantage.
From the table, the median position is calculated as:
[tex]\mathbf{Median = \frac{1}{5} th}[/tex]
[tex]\mathbf{Median = 0.2\ nd }[/tex]
The 0.2nd data falls in the 0.4 field goal category.
So, the median element is:
[tex]\mathbf{Median = 0.4}[/tex]
However, the distribution of the table are concentrated on the left.
This means that, the distribution is not uniform, instead it is skewed right.
A uniform distribution has a skewness of 0.
Hence, Fatima's claim is not supported by the table

PLEASE HELP ME OUT!!
Answer:
Hello!
Judging by the question you have provided I have come up with the correct solution:
y=25x+175
Step-by-step explanation:
The way I came up with the solution is by understanding how to write the correct equation using the correct variables in the correct places.
In the equation y=mx+b, the variable "b" will always be an independent variable.
The independent variable of Candace equation is "175 gallons". This is because this amount does not change throughout the entire equation.
Next, the variable "m" will always be a dependent variable.
The dependent variable of the Candace equation is "25 gallons". This is because this variable is effected by "x amount of hours".
So when you input these given variables in the correct places you get:
y=25x+175
