Answer:
1. 4(10+8) 40+32=72
2. 5(15*3-2) 5(45-2) 225-10=215
Step-by-step explanation:
Answer:
<h2>y = 1</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:

<em>m</em><em> - slope</em>
<em>(x₁, y₁)</em><em> - point on a line</em>
We have <em>m = 0, (3, 1) → x₁ = 3, y₁ = 1</em>.
Substitute:

<em>add 1 to both sides</em>

Other method.
If the slope is equal 0, then it's a horizontal line.
The equation of a horizontal line: <em>y = a</em>.
We have the point on a line (3, 1) → x = 3, y = 1.
Therefore the equation is <em>y = 1</em>.
Answer:
Step-by-step explanation:
lets say in the shown triangle x=165
so speed 
and 
Also since distance = speed* time
time = pi minutes = pi/60 seconds
y = 
y = 
Now using the pythagorean :

<u>derivate the equation so we get :</u>


m/s
So Rate of change = <u><em>25.387 m/s</em></u>
Answer:
Yes
Step-by-step explanation:
Each input must only have one output. In other words, an x-value goes with one y-value. in this model, each input has an output.
