The correct answer is the second choice:

<BCD + <CDA = 180

Can anyone help me with inverse function please?

${h}^{ - 1} oh(x) = x \\ {h}^{ - 1} (4x + m) = x \\ 2k(4x + m) + \frac{5}{8} = x \\ 8kx + 2km + \frac{5}{8} = x$

k and m must satisfy 8k = 1 mean k = ⅛

and 2km+⅝=0 mean m = -5/2

A lawnmower that regularly sells for $150 is on sale for $120. By what percentage was the price decreased?

yanalaym [24]

Answer:

20%

Step-by-step explanation:

Find the difference of both prices.

150 - 120 = 30

Calculate the ratio of the decrease in price to the original price.

30/150 = 0.2

Multiply the decimal by 100 to get your percentage.

0.2(100) = 20
