Answer:
f'(x) = (x + 1)/15
Step-by-step explanation:
f(x) = 15x -1,
Think of the term "f(x)" as a single variable, then solve for the term "x", manipulate the equation like how one would manipulate a literal equation, by inverse operations.
f(x) = 15x - 1
+1 +1
f(x) + 1 = 15x
/15 /15
(f(x) + 1)/15 = x
This means that (denote in the way one would denote an inverse of a function);
f'(x) = (x + 1)/15
Check the picture below.
notice the sides, now, on the second triangle, side 6 slants a bit more to fit in 13, on the third triangle, side 6 slants even further to fit 13 in, now, if 6 were to slant completely, it'll make a flat-line with side 5, and there will be a triangle no more.
but even if side 6 would stretch to a flat-line, 5+6 is just 11, whilst side 13 is longer than that, so no dice.
Answer:
2/4 or 1/2
Step-by-step explanation:
i used a numbers chart to break the numbers down.
Conversions:
1 yard = 36 inches
The store only sells fabric by the by the quarter yard.
<h2><u><em>
The yellow fabric: 450/36 = 12.5 square yards</em></u></h2><h2><u><em>
The blue fabric: 478/36 is around 13.3 square yards</em></u></h2>
Total Amount: 12.5+13.3=
<h2><u><em>
25.8 square yards</em></u></h2>
Simple...
you have:
1.) Find the slope of the line using (-2,1) and (3,6)
Using


m=1 (slope)
2.)Tell whether the equation, 8y+3=5x+3, is a direct variation.
y=

(None)
3.)What is the slope and y-intercept of the graph of the equation y=2x+3?
Slope =2
y-intercept=3
C.
Thus, your answer.
