Answer:
Given f(x) = 5x, find each of the following:
f(3) = 15
f(-2) = -10
fo
f(-1) = -5
f(8) = 40
f(-4) = -16
Step-by-step explanation:
When you have a value of x, it shows up inside the parenthesis.
For example: f(3) means x = 3.
Once you know what x is, you just have to plug in it's value into the original function.
So f(x) = 5x where f(3) means (5*3) or 15.

Which set of ordered pairs gives the polygon shown?
A. (-4, 2), (-4,-5),(1.5,-5),(1.5,2
B. (1.5,2),(1.5,-4.5),(-4.5,-4),(2,-4)
C. (-4,-4.5),(-4.5,1.5),(1.5,2),(-4,2)
D. (1.5,-4.5),(-4,-45,(-4,2),(1.5,2)
The correct option is D as explained below.
What is a polygon?In Mathematics, a polygon can be defined as a two-dimensional geometric figure that consists of straight line segments and a finite number of sides. Additionally, some examples of a polygon include the following:
• Triangle
• Quadrilateral
• Pentagon
• Hexagon
• Heptagon
• Octagon
• Nonagon
Generally speaking, the measure of the angle at the center of a regular polygon is equal to 360 degrees. Therefore, the smallest angle of rotation that maps (carries) a regular polygon onto itself can be calculated by using this formula:
α = 360/n
Set of ordered pairs for the polygon, the polygon can be shown as follows:
Start at the point (1.5, -4.5).
given a line segment to the point (-4, -4.5).
given another line segment to the point (-4, 2).
given a final line segment to the point (1.5, 2) to complete the polygon.
Therefore, The resulting shape will be a rectangle with two shorter sides of length 5.5 units and two longer sides of length 6.5 units. So the correct option is D

An angle is a figure created by two rays. The value of x is 10 units.
What is an angle?An angle is a figure created by two rays, known as the sides of the angle, that have a common terminus, known as the vertex of the angle.
The line VT bisects ∠STU, therefore, the two triangles will be similar because VT is the common line between the two triangles while ∠STV and ∠UTV are equal angles. Therefore, we can write,
[tex]\dfrac{UT}{UV} = \dfrac{ST}{SV}\\\\\dfrac{3x+2}{24} = \dfrac{12}{9}\\\\3x+2 = \dfrac{12 \times 24}{9}\\\\\\3x+2=32\\\\x=10[/tex]
Hence, the value of x is 10 units.

In a class of 32 students
the mean height of the 14 boys is 1.56 meters.
the mean height of all 32 students is 1.515 meters.
Work out the mean height of the girls.
Please help
WINNER GETS BRAINLIEST!!!!!!
Answer:
1.48 m
Step-by-step explanation:
In a class of 32 students
the mean height of the 14 boys is 1.56 meters.
the mean height of all 32 students is 1.515 meters.
Total number of students = 32
Mean height of all students = 1.515
We can obtain the sum of all student's height :
Number if students * mean height
= 32 * 1.515
= 48.48
Number of boys = 14
Mean height of boys = 1.56m
We can obtain the sum of all boys height :
Number if students * mean height
= 14 * 1.56
= 21.84
Number of girls :
All students - Number of boys
32 - 14 = 18
Sum of girls height :
48.48 - 21.84 = 26.64
Mean height of girls :
Sum of girls height / Number of girls
26.64 / 18
= 1.48 m

how do I determine if a function is even, odd, or neither
Answer:
The way to do is dow below
Step-by-step explanation:
You may be asked to "determine algebraically" whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

If EG and HJ are parallel lines and m
Answer:
m JIK = 122°
Step-by-step explanation:
HERE, L || M
So, m JIK = m GFI
( since they are corresponding angles pair )
so, m JIK = 122°
The measure of ∠ JIK is 122°
What are corresponding angles?Corresponding angles are angles that occur on the same side of the transversal line and are equal in size.
Given that, EG and HJ are parallel lines and m is transversal
∵ ∠ GFI and ∠ JIK are corresponding angles, and corresponding angles between two parallel lines are equal.
∴ m ∠ GFI = m ∠ JIK = 122°
