Answer:
{-2, 0, 1, 3}
Step-by-step explanation:
The domain is the list of the x-values in the (x, y) pairs:
{-2, 0, 1, 3}
Answer:
look at explanation (I go down the first column of scenarios and then move on to the right column)
Step-by-step explanation:
1) The first one will be same as original because the decrease and increase are the same, and happen right after each other so you get the same amount
2) Second one you get greater than original. You're doubling the initial value, and then decreasing by a smaller percentage, so you still get greater than your initial value
3) Third you get greater than original. You're adding 50% of the initial value, and decreasing by 33.5% of the new value, which will still give you more than the original
4) Fourth, you get greater than original. You're adding 60% of the initial value, and then decreasing by 40% of the new value, which will still give you greater than the initial value
5) Fifth you get less than the original. You're decreasing by 75%, and then adding 50% of the new value, which still gives you less than the initial value
Answer:
[2(x+10)]°+(3x-30)°=180°[vertically opposite angle]
2x+20+3x-30=180°
5x-10=180°
5x=180-10
5x=170
x=170/5
x=34
20 can go into 98, 4 times which leaves 18 as a remainder.
Answer:
1. 15
2. 8
Step-by-step explanation:
The two sequence are geometric progression GP, because they follow a constant multiple (common ratio)
The nth term of a GP is;
Tn = ar^(n-1)
Where;
a = first term
r = common ratio
For the first sequence;
The common ratio r is
r = T3/T2 = 540/90 = 6
r = 6
T2 = ar^(2-1) = ar
T2 = 90 = ar
Substituting the values of r;
90 = a × 6
a = 90/6
a = 15
First term = 15
2. The sam method applies here.
Common ratio r = T3/T2 = 128/32 = 4
r = 4
T2 = ar^(2-1) = ar
T2 = 32 = ar
Substituting the values of r;
32 = a × 4
a = 32/4
a = 8
First term = 8
