Answer:
17
Step-by-step explanation:
-6² ÷ 12 - 2(-7)
-36 ÷ 12 - 2(-7)
-36 ÷ 12 + 14
-3 + 14
= 11
<span><span><span><span>The word "slope" may also be referred to as "gradient", "incline" or "pitch", and be expressed as:
A special circumstance exists when working with straight lines (linear functions), in that the "average rate of change" (the slope) is </span>constant.<span> No matter where you check the slope on a straight line, you will get the same answer.</span> </span></span><span><span><span> Non-Linear Functions:</span>When working with <span>non-linear functions, </span>the "average rate of change" is not constant.
The process of computing the "average rate of change", however, remains the same as was used with straight lines: two points are chosen, and is computed.<span>FYI: </span>You will learn in later courses that the "average rate of change" in non-linear functions is actually the slope of the secant line passing through the two chosen points. A secant line cuts a graph in two points.</span></span></span>
When you find the "average rate of change" you are finding the rate at which (how fast) the function's y-values (output) are changing as compared to the function's x-values (input).
When working with functions (of all types), the "average rate of change" is expressed using<span>function notation.</span>
Sub in 5 for x
y=(5)2 -9
y= 10-9
y= 1
Answer:
Team 3 Turtle, by 4 minutes
Step-by-step explanation:
The speeds of each of the turtles can be computed from ...
speed = distance/time
Then for each of the turtles, the training pace is ...
Team 1 Turtle: (18 ft)/(6 min) = 3 ft/min
Team 2 Turtle: (12 ft)/(4 min) = 3 ft/min
Team 3 Turtle: (10 ft)/(2 min) = 5 ft/min
The times required to cover the 30 ft distance at these paces are ...
time = distance/speed
3 ft/min ⇒ (30 ft)/(3 ft/min) = 10 min
5 ft/min ⇒ (30 ft)/(5 ft/min) = 6 min
The 2nd-place finishers will take 10-6=4 minutes longer.
The expected winner is Team 3 Turtle by 4 minutes.
Answer:
The first one, the third one, and the fourth one.
Step-by-step explanation:
i just put the ones that are correct. If you want me to write out why the incorrect ones are incorrect, let me know.
1.
-6=3x
-6= 3(-2)
-6= -6
3. -8= x+x+x+x
-8= -2+-2+-2+-2
-8= -8
4. x/2= (-1)
-2/2 =(-1)
-1= -1
