Answer: ∠BDA = 21; CB = 30

have:

sin ∠BDC = \frac{4x+6}{BD}

sin ∠ADB = \frac{7x-12}{BD}

because ∠BDC = ∠ADB => sin ∠BDC = sin ∠ADB

=> \frac{4x+6}{BD}=\frac{7x-12}{BD}

=> 4x + 6 = 7x -12

<=> 3x = 18

<=> x = 6 => CB = 4.6 + 6 = 30

Answer:

C. y = | x | – 13

Step-by-step explanation:

y = | x | – 13

Answer:

y = |x| -13

Step-by-step explanation:

recall for any function y = f(x), to translate the function vertically by any value "a", we simply have to add "a" to f(x).

If a is positive, then the graph is translated in the positive y-direction (i.e upwards), if a is negative, then the graph is translated in the negative y-direction (i.e downwards)

In our case , the graph is translated vertically by 13 units (i.e a = 13) and it is to be translated downwards (i.e negative)

hence we add a= -13 to the original function.

y = f(x) + (-13)

y = |x| + (-13)

y = |x| -13

ira [324]

Answer:

The 24 pack for 24 dollars!

Step-by-step explanation:

This is because you see that 12 is 1/2 of 24 and if you do 13x2 you get 26$ so for the 12 pack if you double it you will be paying 2$ more than if you got the OG 24 pack
