Hey there!
Use the slope formula:
[tex]\bold{\displaystyle\frac{y2-y1}{x2-x1} }[/tex]
[tex]\bold{\displaystyle\frac{0-0}{5-0} }[/tex]
[tex]\bold{\displaystyle\frac{0}{5} }[/tex]
[tex]\bold{0}[/tex]
There's an easier way to determine the slope.
As you can see, the y-coordinates of the points that the line passes through (0, 0) --> the origin and (5, 0).
This means the slope's 0.
Remember that
if the points that a line passes through have the same y-coordinates, then the slope of the line is 0.Hence, the slope's 0.
Hope everything is clear.
Let me know if you have any questions!

Are the triangles similar?
The graph of the linear equation 3x + 5y
= 15 cuts the x-axis at the point ________.
Answer:
(0,5)
Step-by-step explanation:
3x-5y=15
Plug in 0 for y, because we are trying to find the value of x, when y is 0
so, 3x-5(0)=15
3x=15 Divide both sides by 3
x=5
so the answer in coordinate form is (0,5)

Aubrey is looking to purchase sons for her phone. Plan A will cost $2.00 per song. Plan B will require a $15 joining fee and $1.49 per song. When will Plan A be a less expensive option for Aubrey? When will Plan B be a less expensive option for Aubrey? (SHOW ALL WORK BY TYPING HERE). * 3 points
Given :
Plan A will cost $2.00 per song. Plan B will require a $15 joining fee and $1.49 per song.
To Find :
When will Plan A be a less expensive option for Aubrey? When will Plan B be a less expensive option for Aubrey?
Solution :
Let, after x songs Plan A will be less expensive.
So,
2x < 15 + 1.49x
0.01x < 15
x < 29.41 i.e x < 30
Before, 30 songs Plan A will be less expensive.
After, 30 songs Plan B will be less expensive.
Hence, this is the required solution.

Two angles form a linear pair. The measure of one angle is 1/3 of the other angle. Find the measure if each angle
Answer:
The measure of the angles is 45° and 135°
Step-by-step explanation:
When two lines intersect, a linear pair of angles is formed. Two angles are said to be linear if they are adjacent, so a linear pair of angles must add up to 180 degrees.
Let's call x and y the two required angles. Knowing they form a linear pair:
x+y=180
We also know one angle is 1/3 of the other angle, thus:
x=y/3
Or, equivalently:
3x=y
Substituting y into the first equation:
x+3x=180
Simplifying:
4x=180
Solving:
x=180/4=45
The other angle is:
y=3x=3\cdot 45=135
Thus the measure of the angles is 45° and 135°

use the slope to determine if lines AB and CD are parallel, perpendicular, or neither. (please help asap!!)
Answer:
It’s perpendicular
Step-by-step explanation:
If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.
lines AB and CD are perpendicular to each other
This is all about getting the slope of a line between two coordinates.
The formula for the slope in this case is;
m = (y2 - y1)/(x2 - x1)
We are given coordinates of A and B as;
A(9, 2) and B(-1, 8)
Thus;
m = (8 - 2)/(-1 - 9)
m = 6/-10
m_ab = -6/10 = -3/5
For coordinates of C and D, we have;
C(-5, 16) and D(-8, 11)
Thus;
m_cd = (11 - 16)/(-8 - (-5))
m_cd = -5/-3 = 5/3
For the slopes to be parallel, they have to be equal but for the slopes to be perpendicular, one of them would have to be negative inverse of the other.
We see that; m_cd = 5/3 is same as -1/(m_ab) = -1/(-3/5) = 5/3
Thus, lines AB and CD are perpendicular to each other.

3) 5

Answer:
the answers is -10. I hope this helps you out
The solution to the inequality 3(x-4) ≥ 5x + 2 is when x = -10
Therefore, the correct answer is Option A. -10
Given data:
The inequality relation is represented as 3(x-4) ≥ 5x + 2
On simplifying the equation:
From the distributive property:
3x - 12 ≥ 5x + 2
Adding 12 on both sides:
3x ≥ 14 + 5x
Subtracting 5x on both sides:
-2x ≥ 14
Divide by -2 on both sides:
x ≤ -7
The inequality relation changes when the operand is -1.
So, the values of x should be less than -7
Hence, the solution is when x = -10, the inequality satisfies.

Paul's car is 16 feet long. He is making a model of his car that is 1/8 the actual size. What is the length of the model?
The length of the model car is 2 feet
Paul's car is 16 feet long. To create a model of his car that is 1/8 the actual size, we need to determine the length of the scaled-down model.
To find the length of the model, we multiply the length of the actual car by the scaling factor of 1/8.
Length of the model = Length of the actual car * Scaling factor
Length of the model = 16 feet * (1/8)
Length of the model = 16 feet * 1/8
Length of the model = 16/8 feet
Length of the model = 2 feet
Therefore, the length of the model car is 2 feet. The model car is 1/8 the size of the actual car, so it measures 2 feet in length.
This scaled-down model allows Paul to create a representation of his car that is much smaller and more manageable while maintaining the same proportions as the original car.

II. Let f(x) = 9 – x , g(x) = x2 + x, and h(x) = x – 2. Compute the following:
9. H(g(x)) and h(g(f(x)))
Answer:
[tex]h(g(x))=x^2+x-2[/tex]
[tex]h(g(f(x))= x^2-19x+88[/tex]
Step-by-step explanation:
Composite Function
Suppose f(x) and g(x) are real functions, the composite function named [tex](f\circ g)(x)[/tex] is defined as:
[tex](f\circ g)(x)=f(g(x))[/tex]
The composite function can be found by substituting g into f.
We are given these functions:
[tex]f(x)=9-x[/tex]
[tex]g(x)=x^2+x[/tex]
[tex]h(x)=x-2[/tex]
Find:
a) h(g(x))
Substituting g into h:
[tex]h(g(x))=x^2+x-2[/tex]
b) h(g(f(x))
First we find g(f(x)):
[tex]g(f(x))=(9-x)^2+(9-x)[/tex]
Operating:
[tex]g(f(x))=81-18x+x^2+9-x[/tex]
Simplifying:
[tex]g(f(x))=90-19x+x^2[/tex]
Now find h(g(f(x)) replacing the above equation into h:
[tex]h(g(f(x))= 90-19x+x^2-2[/tex]
Simplifying and rearranging:
[tex]h(g(f(x))= 88-19x+x^2[/tex]
[tex]h(g(f(x))= x^2-19x+88[/tex]

11
Step-by-step explanation:
Well basically i took 19 1/4 and divided it by 1 3/4 and there for i got 11. YOUR WELCOME.
There are 11 pieces of ribbon doe Nadya have.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Nadya has 19 1/4 yards of ribbon she cuts ribbon into pieces that measure 1 3/4.
Now, We can find the number of pieces as;
⇒ 19 1/4 ÷ 1 3/4
⇒ 77/4 ÷ 7/4
⇒ 77/4 × 4/7
⇒ 77/7
⇒ 11
Therefore, There are 11 pieces of ribbon doe Nadya have.
