Which statement best describes g(x) = 3 x + 6 - 8 and the parent function f(x) = 3x ?
The domains of g(x) and f(x) are the same, but their ranges are not the same.
The ranges of g(x) and f(x) are the same, but their domains are not the same.
The ranges of g(x) and f(x) are the same, and their domains are also the same.
The domains of g(x) and f(x) are the not the same, and their ranges are also not the same.
Answers
Answer:
The answer is C: the ranges of g(x) and f(x) are the same, and their domains are also the same.
Step-by-step explanation:
Just took the test on edge!! :)
Option C The ranges of g(x) and f(x) are the same, and their domains are also the same is correct.
What is domain?
List of values of x an equation can satisfy is called Domain.
What is range?
List of values y the function can generate is called range
For example, f(x)=x
it can satisfy real domain i.e. x∈R
and range is R
g(x) = 3 x + 6 - 8 and f(x) = 3x
Domain for both the function is R
Both the function can satisfy all the real numbers, so its range is also R.
Therefore,Option C The ranges of g(x) and f(x) are the same, and their domains are also the same is correct.

does anyone know how to solve this? I have to find lengths FJ, DM, and EM
Answers
Answer:
FJ= 24
DM= 16
EM= 18
Step-by-step explanation:
The centroid is twice as close along any median to the side that the median intersects as it is to the vertex it emanates from.
So in the case of FJ, the median intersects the side at point J and extends from vertex F. This means that FM is twice as long as MJ. It tells us that MJ is 8, so MF would be 16. Now because FJ is just FM+MJ, FJ is 24.
It also tells us that DK is 24, which means that DM+MK = 24. If DM is twice as long as MK, that would make MK equal to 8 and DM equal to 16
Similarily, EM would be twice as long as ML. It says that ML=9 so that would make EM=18

Answers
Let x = number of 20p coins
10+50+20x=200 10p + 50p + x(20p) = 200p (100p=1 pound)
60 + 20x = 200
subtract 60 from each side
20x=140
divide both sides by 20
x=140/20=14/2=7

What is the perimeter and area of the composite figure?
Answers
Step-by-step explanation:
▪AB = AC - EF
= 13 cm - 7 cm
= 6 cm
▪BD = CF - DE
= 16 - 8 cm
= 8 cm
BC = EF
perimeter = CF + EF + DE + AD + AB + BC
= 16 + 7 + 8 + 10 + 6 + 7
= 54 cm
Area of triangles = 1/2 × AB × BD
= 1/2 × 6 × 8
= 48/2
= 24 cm²
Area of rectangle = CF × EF
= 16 × 7
= 112 cm²
the total area = 24 + 112
= 136 cm²

Answer:
m<1 = 150°
Step-by-step explanation:
Given:
m<1 = (4x + 50)°
m<2 = (7x - 25)°
Required:
m<1
Solution:
To find m<1, we need to create an equation that will enable us determine the value of x.
Thus,
4x + 50 = 7x - 25 => corresponding angles are congruent to each other
4x + 50 - 7x = 7x - 25 - 7x (subtraction property of equality)
-3x + 50 = - 25
-3x + 50 - 50 = -25 - 50 (substraction property of equality)
-3x = -75
-3x/-3 = -75/-3 (division property of equality)
x = 25
✅m<1 = (4x + 50)°
Plug in the value of x
m<1 = 4*25 + 50 = 100 + 50
m<1 = 150°
