Answer:
Step-by-step explanation:
Average rate of change is the same thing as the slope. This is a quadratic so the slope is not something that is constant like it is in a line. Here you have the x coordinates of 1 and 5; each one of these x coordinates has a y coordinate that goes with it. If we draw a line from one of these coordinates to another, that line will have a slope. That is the slope we are trying to find. Thus, we need the y coordinates that go with each of these x coordinates. To do that, plug x into the equation and do the math to find y:
Let's start with x = 1.
f(1) =
so
f(1) = 16 and the coordinate is (1, 16).
f(5) =
so
f(5) = -8 and the coordinate is (5, -8). Now we apply the slope formula:
So the answer is -6.
Answer:
<em>t = -1.1</em>
Step-by-step explanation:
3.1 - 1.3 = t + 2.9
1.8 = t + 2.9
-1.1 = t
t = -1.1
It's the first oneeeeeeeeeeeeeee
To solve this problem we need to know the form of the general equation of the line. That is, y= mx+b where m is the slope and b is the intercept. We are already given the y-intercept (2) our next step is to fin the slope. Substitute the point give (1,1) in the equation y= mx+2 and then solve for m. The slope is then -6. The final equation is y = -x+2 or <span>x + y - 2 = 0</span>
The number 1000 less than 921,438 is 920,438. What you do is take 921,438 and subtract 1000 from it.
