Answer:
x = 133/4 or x = 33.25 decimal
Step-by-step explanation:
Solve for x:
7 - 4 x = -126
Subtract 7 from both sides:
(7 - 7) - 4 x = -7 - 126
7 - 7 = 0:
-4 x = -7 - 126
-7 - 126 = -133:
-4 x = -133
Divide both sides of -4 x = -133 by -4:
(-4 x)/(-4) = (-133)/(-4)
(-4)/(-4) = 1:
x = (-133)/(-4)
Multiply numerator and denominator of (-133)/(-4) by -1:
Answer: x = 133/4
Answer:
I am not sure .but i will try
i think so i will give correct answer
perpendicular of triangle is 22-10 cm =12 cm bcz both sides of triangle are equal =22
area of rectangle l×w= 22×17=374
area of triangle =h×b/2 Now we r not having h
lets find it
use pythagorus theorum (h2=P2+b2....2 here is square)
h=22.5cm
22.5×19=427(area of triangle )
374+427=801cm sq
i tried my best dont know its righr of wrong
pls mark me as brainlieast
The correct answer would be -1/8
Answer:
The maximum profit of $ 10277.32____ can be made when the selling price of the dog food is set to $ _34___ per bag.
Step-by-step explanation:
Profit = Revenue - Cost
P(x) = R(x) -C(x)
= -31.72x^2 + 2,030x
-( -126.96x + 26,391)
Distribute the minus sign
= -31.72x^2 + 2,030x+126.96x - 26,391
Combine like terms
= -31.72 x^2 + 2156.96 x - 26391
This is a parabola. It is facing downwards. The maximum profits is at the vertex ( where the max is)
vertex = h = -b/2a = -(2156.96)/(2*-31.72) = -2156.96/-63.44=34
Evaluate P(x) at x=34 to determine the profit
P(34) = -31.72 (34)^2 + 2156.96 (34) - 26391
-36668.32+73336.64-26391
10277.32
