Answer:

f(x)=-4x+/4

let y=f(x)

y=-4x+4

interchange the role of x & y

x=-4y+4

x-4=-4y

(x-4)/-4=y

y=-(x-4)/4

f-¹(x)=-(x-4)/4

yeah you are right

The price for a TV was decreased by 20% and then by 10%. By what percent was the new price lower than the original?
Finger [1]
Let's say the tv was 100$ . Reduced by 20% means the tv is now 100 - 20 = 80% of the original price.

0.8(100) = 80$
Reduced again; by 10% means that it is now 100-10 = 90% of the 80$
0.9(80) = 72$

sale price ÷ original price

72$ / 100$ = 0.72 which is 72% of the original price. Which is a mark down of:
100 - 72 = 28%

The new price is 28% lower than the original price.

Let f(x) = 5x2 – 4x and g(x) = 5x + 1.
Nastasia [14]

f(x) = 5x^2 - 4x

g(x) = 5x + 1

Therefore f - g = 5x^2 - 4x - (5x + 1)

= 5x^2 - 4x - 5x -1

= 5x^2 -9x - 1


Hope it helps :)

A store salesperson is paid 3% of his sales as a commission. He made sales of $2500. How much was his commission?​
PolarNik [594]

1) Write 3% as 3/100

2) Since, finding the fraction of a number is same as multiplying the fraction with the number, we have:

\frac{3}{100} of 2500 = \frac{3}{100} × 2500

Therefore, the answer is 75

If you are using a calculator, simply enter 3÷100×2500 which will give you 75 as the answer.

Commission = $75
