The value of the f(7) is -3 if the function is f(x) = x – 10 after plugging x = 7 in the function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = x -10
The above function represents the linear function.
To find the value of f(7) plug x = 7 in the function.
f(7) = 7–10
f(7) = -3
Thus, the value of the f(7) is -3 if the function is f(x) = x – 10 after plugging x = 7 in the function.

Step-by-step explanation:
Answer:
-0.25
Step-by-step explanation:
xD im a bit late :P
we can pick any 2 points on the line.
let's pick, (-1, 2) and (-3, 1)
Alright, so the formula to calculate slope is in the attachment below.
If you're a bit confused on what the little 2 and 1 at the bottom of each of those numbers are representing the points. So let's say (-3, 1) is point 2. And (-1, 2) is point 1.
the variable "y" is the y-coordinate.
the variable "x" is the x-coordinate.
And all we need to do now is just sub in the values and that's your answer.
so we have the 2 y-coordinates, 1 and 2.
We subtract them. 1-2=-1
then we have the 2 x-coordinates, -1, -3
-1-3=-4
so -1/-4 is -0.25

Which function has an inverse that is a function?
b(x) = x2 + 3
d(x) = –9
m(x) = –7x
p(x) = |x|
Answer:
All but the second one
Step-by-step explanation:
Find the inverse of each function:
b(x)=x^2+3
y=x^2+3
x=y^2+3
x-3=y^2
sqrt(x-3)=y
This inverse function is a function
d(x)=-9
y=-9
This doesn't have an inverse function
m(x)=-7x
y=-7x
x=-7y
-1/7x=y
This inverse function is a function
p(x)=|x|
y=|x|
x=|y|
x=y
This inverse function is a function
Therefore, all but the second function have inverses that are functions
Answer:
All but the second one have inverse functions

Step-by-step explanation:
through (2, -4) and parallel to y= 9/2x+3
Answer:
y=[tex]\frac{9}{2\\}[/tex] x-13
Step-by-step explanation:
first, since it's parallel the slope has to be the same and the y-intercept has to be different.
you will have y=9/2x+b
find b, by using the points you are given so you will get
-4=(9/2) times (2)+b.
then when sloving you will get b=-13 and so the full equation will be
y=9/2x-13

Mike and Charlie are facing each other. There is a flagpole exactly halfway between them. Their line of sight to the top of the flagpole is 16 feet, with an angle of elevation of 60°.
Mike and Charlie both calculated the height of the flagpole as shown below.
Mike's Calculation Charlie's Calculation
Examine Mike and Charlie's calculations and complete the statement below.
The person with the incorrect reasoning for the height of the flagpole is
, because he incorrectly selected the
function, when he should have utilized the
function.
Answer:
Charlie is incoerre
Step-by-step explanation:
Given that :
Line of sight to top of flagpole = 16 feets
Angle of elevation = 60°
The height of the flagpole :
Applying trigonometry to the drawing in the attached picture :
We use:
Sinα = opposite / hypotenus
This enables us to use the value of the hypotenus (line of sight) to obtain the missing height value (h)
Sin(60°) = h / 16
h = 16 * sin 60
h = 16 * 0.8660254
h = 13.856406
Hence flagpole is about 13.86 feets high
Charlie's reasoning is incorrect, the line of sight constitutes the hypotenus and not Adjacent and hence, shoul
The scatter plot shows the relationship between years of experience and hourly pay at one factory.
describe the relationship between experience and pay years of work
Answer:
I'm pretty sure it's B.
Step-by-step explanation:
The more experience you have, the better you are at your job. If your doing better at your job, you get better pay.
Good luck on the test BTW. =)
The correct answer is option B which is the hourly pay usually increases with the work experience.
What is a scatter plot?Scatter plots are graphs that show how two variables in a data collection relate to one another. On a two-dimensional plane or in a Cartesian system, it represents data points.
In the given graph horizontal axis contains the years of experience and the vertical axis consists of the hourly pay of an employee. We can see that the employees with higher experience are paid a higher hourly amount.
Therefore the correct answer is option B which is the hourly pay usually increases with the work experience.

Ramiro se dedica a circular terrenos se le presenta un trabajo se circular un terreno cuadrado con una superficie de 470 metro cuadrados y le piden que lo circulen con 4 hilos de alambre de puas sobre postes. ¿cuantos metros lineales con alambre de puas nesecita?
Answer:
346.88 meters
Step-by-step explanation:
Given that the area of the square-shaped terrain is 470 square meters.
Let a be the side of the terrain, so
Area of the square-shaped terrain, [tex]a^2=470[/tex] square meters.
Therefore, the length of one side, [tex]a=\sqrt {470}=21.68[/tex] meters.
The length of single thread wire required in circulating the square-shaped terrain = the perimeter of the square-shaped terrain
As the perimeter of a square having side a = 4a
So, the length of single thread wire required in circulating the square-shaped terrain= 4 x 21.68 =86.72 meters
Therefore, the length of 4 thread wire required in circulating the square-shaped terrain= 4 x 86.72=346.88 meters.

Point B is halfway between A and C. The distance from C to D is the same as the distance from D to E, which is the same as the distance from E to F. The area of triangle ACF is 180 cm2. How many square centimeters is the shaded area of triangle BCE?
Answer:
3
Step-by-step explanation:
3
ΔBCE is half the base length and two third the height of ΔACF, therefore,
the area of ΔBCE is less than half the area of ΔACF.
The area of triangle ΔBCE is 60 cm².
Reasons:
In ΔACF, we have;
B = The midpoint of AC
Point E and point D are points on side CF
Distance C to D = Distance D to E = Distance E to F
Area of ΔACT = 180 cm²
Required:
Area of ΔBCE
Solution:
[tex]Area \ of \, \Delta ACF = \mathbf{\dfrac{1}{2} \times AC \times CF} = 180 \ cm^2[/tex]
[tex]In \ \Delta BCE, \, BC = \dfrac{1}{2} \times AC \ and \ CE = \dfrac{2}{3} \times CF[/tex]
Therefore;
[tex]Area \ of \ \Delta BCE = \dfrac{1}{2} \times BC \times CE = \dfrac{1}{2} \times \left(\dfrac{1}{2} \times AC \ \right) \times \dfrac{2}{3} \times CF[/tex]
[tex]\dfrac{1}{2} \times \left(\dfrac{1}{2} \times AC \ \right) \times \dfrac{2}{3} \times CF = \dfrac{1}{2} \times \dfrac{2}{3} \times \left(\dfrac{1}{2} \times AC \ \right)\times CF = \mathbf{\dfrac{1}{3} \times Area \ \Delta ACF}[/tex]
Therefore;
[tex]Area \ of \ \Delta BCE = \dfrac{1}{3} \times Area \ \Delta ACF = \dfrac{1}{3} \times 180 = 60[/tex]
The area of triangle ΔBCE = 60 cm².
