Slope is (the change in y) / (the change in x).
The formula for slope is:
m = (y2 - y1)/(x2 - x1), with (x1, y1) being one point and (x2, y2) being the second. What you need to do is order the slopes from smallest to largest because slope means the same thing as rate of change.
#17. First, you need to find the slope of function A. To do this, I’m choosing two different points I see on the graph: (1,1) and (2,1). I now plug these into the slope formula:
m = (1-1)/(2-1) = 0/1 = 0.
The slope for function A = 0
To find the slope for function B, you can choose any two points. I’m going to use (3,0) and (6,1)
m = (1-0)/(6-3) = 1/3
The slope for function B is 1/3
For function C, you are already given the slope. That equation is in something called slope-intercept form (y=mx+b), where the x is being multiplied by the slope.
The slope on function C = 1/4
So,, A has the smallest slope, C has the second smallest slope, and B has the largest slope.
#18. The two points in using to find the slope for function A are (0,-3) and (1,0).
m = (0+3)/(1-0) = 3/1 =3
The slope for function A is 3
The two points I’m using for function B are (-2, 10) and (0, 20)
m = (20-10)/(0+2) = 10/2 = 5
The slope for function B is 5
The slope for function C is 1. When the slope is 1, it is not written because any number (other than 0) times 1 equals 1.
Function C has the smallest slope, function B has the second smallest slope, and function C had the largest slope.
It would probably be better for you to try 19 and 20 on your own, and let me or anyone else on Brainly know if you have any questions or something doesn’t make sense.

The speed of the current in a river 6 mph. A very operator who works top part of the river is looking to buy a new boat for his business. Every day, his route takes him 22.5 miles each way against the current back back to the dock, and he needs to make his trip any tour of nine hours. He has a bow in mind, but he can only test it on a leak where there is no current. How fast must the boat go on the lake in order for it to serve the ferry operators needs?
Answers
Answer:
9 mph
Step-by-step explanation:
Speed of current = 6 mph
Distance to travel one way = 22.5 miles
Let speed of the ferry be [tex]x[/tex] mph
Total time taken for round trip is 9 hours
One way the ferry will be going with the current and in the other way the ferry will be going against the current so
[tex]\dfrac{22.5}{x+6}+\dfrac{22.5}{x-6}=9\\\Rightarrow \dfrac{x-6+x+6}{x^2-36}=\dfrac{9}{22.5}\\\Rightarrow \dfrac{2x}{x^2-36}=0.4\\\Rightarrow \dfrac{2x}{x^2-36}-0.4=0\\\Rightarrow 2x-0.4x^2+14.4=0\\\Rightarrow 0.4x^2-2x-14.4=0\\\Rightarrow 4x^2-20x-144=0\\\Rightarrow x=\dfrac{-\left(-20\right)\pm \sqrt{\left(-20\right)^2-4\times 4\left(-144\right)}}{2\times 4}\\\Rightarrow x=9,-4[/tex]
So, the speed of the boat in still water needs to be 9 mph both ways.

Answers
Answer:
Step-by-step explanation:
11). 6x + 3y = 9
3(2x + y) = 9
2x + y = 3
y = -2x + 3
Since variables are of single degree therefore, it's a linear function
12). 3y - 2x = -2x - 12
3y - 2x + 2x = -2x - 12 + 2x
3y = -12
y = -4
Since variable y is of single degree therefore its a linear function.
13). 11y + 4x = -8 + 11y
11y + 4x - 11y = -8 + 11y - 11y
4x = -8
x = -2
Linear function.
14). 4x - 3 + 2y = 8x - 9
4x + 2y - 3 - 4x = 8x - 4x - 9
2y - 3 = 4x - 9
2y = 4x - 9 + 3
2y = 4x - 6
y = 2x - 3
Linear function.

A father is 20 years older than his son. Five years ago,he was three times as old as his son was.Find their present ages
Answers
Answer:
Dad=35, Son=15
Step-by-step explanation:
Well since the dad is 20 year older then the son we can call the son x and the dad x+20. Now five years ago the father was 3 times older then the so we construct the following equation:
x+20−5=3(x−5)
x+15=3x-15
x=15
So now we know that the sons age is 15 meanimg that since the dads 20 years older then him, his age is 20+15 which is 35!

What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
here, we have,
Given:
m∠XYZ = 72 degrees
m∠XYZ and m∠ZYC form a linear pair.
Let's find the measure of ∠ZYC.
To find the measure of angle ZYC, apply the Linear Pair of Angles theorem which states that the sum of angles that form a linear pair is 180 degrees.
Hence, we have:
m∠XYZ + m∠ZYC = 180
72 + m∠ZYC = 180
• Subtract 72 from both sides:
72 - 72 + m∠ZYC = 180 - 72
m∠ZYC = 180 - 72
m∠ZYC = 108 degrees.
Therefore, the measure of ∠ZYC is 108 degrees.
