Answer:
B
Step-by-step explanation:
pretty sure it's right
Use the Product Rule: x^ax^b = x^a + b
3x^-4 + 1 - 5 - 3(5x^-2x + 1)
Simplify -4 + 1 to -3
3x^-3 - 5 - 3(5x^-2x + 1)
Use the Product Rule: x^a x^b = x^a + b
3x^-3 - 5 - 3(5x^-2 + 1 + 1)
Simplify -2 + 1 to -1
<u>3x^-3 - 5 - 3(5x^-1 + 1)</u>
Step-by-step explanation:
1/4(0.25)
1/2 + 1/4 = 3/4 (0.75)
Answer:
10 or 40
Step-by-step explanation:
We have the following equation
-4d²+200d-100= 1500
We want all the non zero on one side and so we subtract 1500
-4d²+200d-1600=0
Solve for d
4( -d²+50d-400)=0
factor (I can explain this part in depth if needed)
4(d-40)(d-10)=0
d=40
d=10
This means that the price either needs to be 40 or 10 dollars
