Answer:
k = -8c.
Step-by-step explanation:
y^2 = kx
Find the slope of the tangent by differentiating:
y' 2y = k
y' = k / 2y = the slope of the tangent.
The given equation of the tangent is y = -2x + c so the slope = -2.
Therefore k/2y = -2 so k = -4y and y = -k/4
y^2 = kx so k^2/16 = kx giving x = k/16.
Substituting for x and y in y = -2x + c:
-k/4 = -2 k/16 + c
-k/4 = -k/8 + c
c = -k/4 + k/8 = -k/8.
So -k = 8c
k = -8c.
Answer:
133.3 (1. dp)
Step-by-step explanation:
First of all we subtract 36 from 60 which is 24 then you divide 24 by 0.18 as its the remaining money divided by the value per mile which gives you the answer: 133.333333 which is rounded
Would be amazing if you marked brainliest :)
Answer:
y = -1/2x - 7
Step-by-step explanation:
y2 - y1 / x2 - x1
-6 - (-5) / -2 - (-4)
-1 / 2
= -1/2
y = -1/2x + b
-5 = -1/2(-4) + b
-5 = 2 + b
-7 = b
Answer:
(w/3)-10
Step-by-step explanation:
Answer:
y = 0x + 2
Step-by-step explanation:
y = 2 is the same as y = 0x + 2. The slope of this line is zero (0) (the line is horizontal).
In slope-intercept form, the equation of this line is y = 0x + 2, which may be left as is or changed to y = 2.
