it is true
Step-by-step explanation:
if you are smart
Answer:
Step-by-step explanation:
f(-9+h)= (-9+h)² = h²-18h+81
f(-9+h)-f(-9)=h²-18h+81 -81 because : f(-9) = (-9)² = 81
f(-9+h)-f(-9)=h²-18h
(f(-9+h)-f(-9))/h=(h²-18h)/h = h(h-18)/h =h-18
lim (f(-9+h)-f(-9))/h = lim(h-18= - 18
h→0 h→0
A is 264 and B is 257 because 785-778=7. so you add 7 to 785 and get 792 then divide by 3, to find candy A. <span>so you subtract 7 from 778 and get 771 then divide by 3, to find candy B. </span>
Answer:
The equation of the perpendicular line is 2 x + y + 1 =0
Step-by-step explanation:
<u><em>Step(i) </em></u>:-
Given equation of the line 2y = x - 18
x - 2y - 18 =0
The equation of the perpendicular line to the given line
b x - ay +k=0
-2 x - y + k =0 this line is passing through the point ( 0 , -1)
⇒ 0 -(-1) + k=0
⇒ 1+k =0
⇒ k = -1
<u><em>Step(ii):-</em></u>
The equation of the line is perpendicular to the line
-2x - y - 1 =0
2 x + y + 1 =0
<u><em>Conclusion:-</em></u>
The equation of the perpendicular line to the given line 2 x + y + 1 =0
