If angle BCD measures 70° then so does angle DBC (because you have formed an isoceles triangle inside the larger ΔABC and the two legs are equal so the two angles have to be equal.   So we have a two 70° angles which leaves 40° for the 3rd angle, which is ∠BDC.   

Since ∠BDC and ∠ADB are supplementary (180°) - that leaves 140° for ∠ADB and is our answer

15. She bought:

3 jeans, $20 each

1 pants, $18

You find the total: 3(20) + 1(18) = $78 then you apply the discount

Since this is between 50-100, you use the 38% discount (decimal form: 0.38)

38% is being subtracted from your total, so you can do this:

100% - 38% = 62%      This is your total after the discount

78(0.62) = 48.36   Your answer is C

16. D   Income is the $ you make from your job

17. A    Budgeting helps you organize and limit your spending and meet financial goals

18. C    Liabilities impacts you negatively, since you have debts to pay off

How does a set of integers differs from the set of whole numbers ? Please help
MariettaO [177]
The difference between set of whole numbers and a set of integers is that:

Whole numbers = {0, 1, 2, 3, 4, 5...}
Integers = {..., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5...}

If we name contents of the first set as n, in the second set you can have 2n-1 numbers (because we count 0 only once in both sets).

Jika f(x-1)=2x+5 dan g1(x-2)=4x+2 maka (g•f)1(0)
spayn [35]
G (x) = x + 1 (fog) (x) = x 2 + 3x + 1 ⇒ (fog) (x) = x 2 + 3x + 1 ⇒ f (g (x)) = x 2 + 3x + 1 ⇒ f (x + 1) = x 2 + 3x + 1 Eg x + 1 = p, then x = p - 1. ⇒ f (p) = (p - 1) 2 + 3 ( p - 1) + 1 ⇒ f (p) = p 2 - 2p + 1 + 3p - 3 + 1 ⇒ f (p) = p 2  + p - 1 So f (x) = x 2  + x - 1 - -> 
                                            ANSWER IS : x 2 + x - 1
