Answer:
B) f(x) = -3/5x +5
Step-by-step explanation:
There are several ways you can write the equation of a line from a list of points. When you look through the list and see that one of them is the y-intercept, then the problem can be easier. When you look through the list of answers and see that the required answer is in slope-intercept form, then you know all you need to do is find the slope to go with the intercept you've located.
The point (x, f(x)) = (0, 5) tells you the y-intercept is 5.
The slope, the change in y divided by the change in x for two points, is ...
... (-1 -2)/(10 -5) = -3/5
This is the slope and the coefficient of x in the linear equation.
Now, we know the y-intercept (b=5) and the slope (m=-3/5), so we can fill in the slope-intercept form of the equation of a line:
... y = mx + b
... y = (-3/5)x + 5
Answer:
x=2/5 or
x=0.4
Step-by-step explanation:
Let
, where
, so that
. Then the ODE is
This is separable, so you have
Integrate both sides, solving for
if possible, then replace using
and solve for
if possible.
Answer:
20.25
Step-by-step explanation:
Just multiply the base and height then divide the results in half.
Hope this helps!
Answer:
x < −60
Step-by-step explanation:
<em><u>Step 1: Add 10 to both sides.</u></em>
−0.4x−10+10>14+10
−0.4x>24
<em><u>Step 2: Divide both sides by -0.4.</u></em>
−0.4x / −0.4 > 24 / −0.4
x<−60
