Answer:
f(3) = 425
f(3) is the elevation of a mountain climber after 3 hours of climbing.
Step-by-step explanation:
So we are given a line that relates time to elevation. We are also given that the equation of the line is f(x) = 125x + 50. From looking at the graph given, we can see that x is the time, in hours, and y, or f(x), is the height, in feet. We are asked to find f(3) and interpret it's meaning.
To find f(3), we would have to find what f(x) is when x = 3. To do this, lets plug in 3 for x into the given equation:
f(3) = 125(3) + 50 = 425
So f(3) = 425. Now, we already know that x is the time in hours and y, or f(x), is the elevation in feet. We set x to 3 when solving for f(3). We have also found that f(3), or y when x = 3, is 425. So f(3), or 425, is the elevation after 3 hours.

Answer:
The equation in the slope-intercept form will be:
Step-by-step explanation:
Given the points
The slope between two points


As the point-slope form is

substituting the values m = -9/10 and (8, -4)

Writing the line equation in the slope-intercept form

where m is the slope and b is the y-intercept
so the equation in the slope-intercept form will be:


subtract 4 from both sides


Therefore, the equation in the slope-intercept form will be:

Answer:
C. both A and B
Step-by-step explanation:
The student incorrectly applied the Distributive Property in Step 1 by not multiplying 8 and 7. Then they added 7 to 7 to cancel them out, but subtracted 7 from 75 instead of adding like they did on the other side of the equal sign.
Step-by-step explanation:
You just have to plug the numbers they give you into the equation. For the first one, you have 0 + 5y = 10; 5y = 10; y = 2. For the second one, x + 5(0) = 10; x + 0 = 10; x = 10. And lastly, for the third one, x + 5(6) = 10; x + 30 = 10; x = -20.
