Inverse of f(x)=-5x+15

Mathematics
1 answer:
Otrada [13]3 years ago
5 0

f(x) = -5x - 15


Let y = f(x)


y = -5x - 15


Switch the x and y places, and solve for y:


x = -5y - 15


-5y = x + 15


y = (x + 15)/-5


y = -(x/5) - 3


So the inverse of : f(x) = -5x - 15 is


-x/5 - 3

The percent decrease of an item that dropped in price from $50 to $43 is​
frez [133]

Answer:

14%

Step-by-step explanation:

The item dropped from $50 to $43 .

Therefore,

Decrease = $50 - $43

= $7

To get the % decrease, divide the decrease by the initial price and multiply the result by 100%

That’s

$7/$50 x 100%

$0.14 x 100%

= 14%

The price of the item decreased by 14%

What is the answer to this equation? Must solve for x.<br> x+5=12x−4
natulia [17]

Answer:

x = 9/11

Step-by-step explanation:

x + 5 = 12x - 4

Subtract x from both sides

x + 5 - x = 12x - x - 4

        5   = 11x - 4

Add 4 to both sides

      5+ 4 = 11x - 4 + 4

            9 = 11x

Divide both sides by 11

         9/11 = 11x/11

          9/11 = x

x = 9/11
