Answer:
can i have brainliest please :)
Step-by-step explanation:
Let the number be x
3x + 5 = 20
3x = 20 - 5
x = 15/3
x=5
We can split them up
dy/dx-12x²=-12 times dy/dx x²=-12 times 2x=-24x
dy/dx9x=9 times dy/dx x=9 times 1=9
so
f'(x)=-24x+9
f'(6)=-24(6)+9
f'(6)=-144+9
f'(6)=-135
Answer:
3 for $3.74
Step-by-step explanation:
If you divide the price by how many bulbs are in it, the 3 for $4.74 is $1.58 a bulb whilst the 2 for $3.74 is 1.87 per bulb. so $1.58 x 12= $18.96 while $1.87 x 12= $22.44
