for different values of x.
Which equation represents h(x)?
HURRY TIMED
Answer:
the last one
Step-by-step explanation:
The equation that represents h(x) = g(x) – f(x) which is correct answer would be option (D)
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
From the given table, the values of x, f(x), g(x), and h(x) are given and there are corresponding values.
Therefore, the corresponding values for
When x = 1
f(x) = 3
g(x) = 18
h(x) = 18 - 15 = 3
When x = 2
f(x) = 12
g(x) = 21
h(x) = 21 - 12= 9
When x = 3
f(x) = -3
g(x) = 24
h(x) = 24 - (-3) = 27
Hence, The equation that represents h(x) = g(x) – f(x).

Consider the diagram.
Planes M and N intersect at line d. Lines a, b, and e are on plane M. Line a is vertical and forms a right angle with line d. Line b is diagonal and goes up and to the right. Line e is at the top of the plane and is close to being horizontal. Line c is on plane N and goes slightly up and to the right.
Lines a and d are
non-coplanar.
parallel.
perpendicular.
skew.
Answer:
perpindicular
Step-by-step explanation:
The line a and line d are perpendicular to each other.
What is a perpendicular lineA perpendicular line is a line that intersect another line at 90 degrees. Perpendicular lines are also called normal lines.
Constructing lines a and dAfter constructing the two lines; line a and line intersect or meet each other at 90 degrees to the horizontal.
Thus, we can conclude that the line a and line d are perpendicular to each other.

11. Four less than a number tripled is the same number increased by ten.
What is the number?
Answer:
7
Step-by-step explanation:
first, we would set up an equation. let 3x-4 represent "four less than a number tripled". "a number" would be represented by x. let x+10 represent "the same number increased by 10".
set 3x-4 and x+10 equal to each other:
3x-4=x+10
next, we would solve this equation for x. first we would get the x together on one side of the equation. we would do this by subtracting x from both sides to remove it from the right side of the equation:
2x-4=10
then, we would get the 2x by itself. we would do this by adding 4 to both sides:
2x=14
finally, we would divide each side of the equation by 2 to find x:
x=7.
The number is 7.

I am thinking of 3 positive whole numbers. the mode is 5,the median is 5, and the range is 9. work out the three numbers.
Answer:
The 3 positive whole numbers would be:
5, 5 , 14
Step-by-step explanation:
We need to find 3 positive whole numbers
The mode is 5
The median is 5
The range is 5
If the mode is 5 it means 5 is most repeated number, as mode is most repeated number of series.
So, it means we have two 5
We know that range can be found by: [tex]Range=Maximun\:Value-Minimum\:Value[/tex]
If we consider minimum value to be 5
[tex]9=Maximun\:Value-5\\Maximun\:Value=9+5\\Maximun\:Value=14[/tex]
So, the 3 positive whole numbers would be:
5, 5 , 14
having mode 5, median 5 and range 9
1/3 in division form
Answer:
Remember, 3 is the same thing as 3/1. Before we can divide, we need to make one more change. We'll switch the numerator and the denominator of the fraction we're dividing by: 1/3 in this example. So 1/3 becomes 3/1.

Which equation represents a circle with its center at (2, -3) and that passes through the point (6,2)?
Answer:
An equation represents a circle with its center at (2, -3) and that passes through the point (6,2) is:
(x - 2)² + (y + 3)² = 41
Step-by-step explanation:
The standard equation of a circle having the center at point C(x₀, y₀) and radius r is given by
(x - x₀)² + (y - y₀)² = r²
It means that every point P(x, y) belonging to the circle must satisfy the equation.
In this particular case, we have that the circle passing through P(x, y) = (6, 2) and the center C(x₀, y₀) = (2, -3).
Then substituting these values in the formula:
(x - x₀)² + (y - y₀)² = r²
(6 - 2)² + (2 - (-3))² = r²
switch sides
r² = (6 - 2)² + (2 - (-3))²
r² = (4)² + (2 + 3)²
r² = (4)²+ (5)²
r² = 16 + 25
r² = 41
r = √41, r = -√41
As r can not be negative, so
r = √41
Therefore , the equation of the circle with center at C = (2, -3) and radius r = √41 is:
(x - 2)² + (y + 3)² = (√41 )²
(x - 2)² + (y + 3)² = 41
Therefore, an equation represents a circle with its center at (2, -3) and that passes through the point (6,2) is:
(x - 2)² + (y + 3)² = 41

Gerri says that if a number is a multiple of 9 it is also a multiple of 3. Do you agree ? Explain
Yes, Gerri is correct and if a number is a multiple of 9 it is also a multiple of 3.
What is a factor?
A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product because the product is divisible by them.
Here, we have
Gerri says that if a number is a multiple of 9 it is also a multiple of 3.
Since 3 is a factor of 9, anything 9 can go into, 3 can also go into.
3x3=9
So, whenever 9 can go into something, it will take 3 times as many 3s to go into that number.
Example:
3 nines = 27
9 threes = 27
9 is 3 times as many as 9.
Hence, Gerri is correct and if a number is a multiple of 9 it is also a multiple of 3.

Write the equation in slope-intercept form of a line that has a slope of 1/3 and passes through the point (-6, 0). y=1/3x, y=1/3x-6, y=1/3x-2, y = 1/3x+ 2
Answer:
Option D: [tex]y=\frac{1}{3}x+2[/tex] is the correct answer.
Step-by-step explanation:
Given that:
Slope of the line = 1/3
Point = (-6,0)
Slope-intercept form of a line is given by:
y = mx + b
We will put the slope and point in the equation to find b.
[tex]0=\frac{1}{3}(-6)+b\\0=-2+b\\b=2[/tex]
Slope intercept form of the given line is;
[tex]y=\frac{1}{3}x+2[/tex]
