Mathematics
1 answer:
Lisa [10]3 years ago

Answer:

So Imma use the explanation area to answer this (I'll link a video on how I solved this.)

Step-by-step explanation:

F(x)=1/3(-5x -4)³-3 (Multiply 1/3 by -5x & -4. Be sure to move the unused parts of the equation down)

F(x)= -1.66x -1.33³-3 (Here we need to use our exponent)

F(x)= -1.66x -2.37 -3 (Here we need to subtract -3 from -2.37)

F(x)= -1.66x - 0.629 (You need to subtract 0.629 from the right side and left side)

-0.629 =  -1.66x (Now since X is attached by multiplication, we need to divide both sides by -1.66)

0.378 = x (this means that your inverse is 0.378)

belka [17]

Answer:

6.5%

Step-by-step explanation:

1000 in a box and he orders 5 boxes.

£77 is between £55 and £79.99 so he will get 6.5% discount.

After the discount he will pay  £71.99

1. 
5u - 2u = 3u (diff. between longest and shortest)
3u = 87cm
1u = 87cm ÷ 3 = 29cm
5u + 4u + 2u=11u
11u = 11 x 29cm = 319cm

Ans: 319cm

2.
9u = 1350
1u = 1350 ÷ 9 = 150
6u + 5u = 11u
11u = 11 x 150 = 1650

Ans: 1650
