Answer:
f'(x) =
Step-by-step explanation:
i) f(x) = 9 / x
ii) f'(x) =
Answer:
d
Step-by-step explanation:
because how the line passes through the positive 4 and its a negative slope along with the fact that it goes down 3 over 2.
**4/5** is equal to .8, so 4/5 is the answer. to check, multiply .8 x 5 = 4
First of all, remember what the equation of a line is:
Where:
m=slope
b=y-intercept.
Given this information, we can start by plugging in what we know, we are given the slope which is 2 so we can fill that in, remember m=slope
To find b, think about what your (x,y) point means:<span>(14,3). When x of the line is 14, y of the line must be 3.
Because we were given the point (14,3)

We need to find the value of b. The 2 is already set and x and y are variables. We want the equation for the line that specifically passes through the given point (14,3).
<span>Plug in for x the number 14 and for y the number 3:
</span>(14,3).
y=mx+b or 3=2 × 14+b,
solving for b: b=3-(2)(14). b=-25.
<span>Plug that in for b:
</span><span>y=2x-25
<span>Final answer:
</span><span>y=2x-25</span></span><span><span>
