Answer:
x = 156/43
Step-by-step explanation:
3x + 5y = 16
8x - y = 28
3x + 5y = 16
5(8x - y = 28)
3x + 5y = 16
40x - 5y = 140
43x = 156
x = 156/43
*sigh, an ugly answer*
The answer is they are all obtuse and all have a 100 degree angle
Answer: 0.2 reduced as a fraction 1/5
Answer:
T' is at (-1,-8)
Step-by-step explanation:
When we translate down 4 units, we will subtract 4 from the y coordinate
T is at (-1,-4)
We need to subtract 4 from the y coordinate
T' is at (-1,-4-4)
T' is at (-1,-8)
Answer:
0.078125.
Step-by-step explanation:
This is a geometric sequence with first term a1 = 20 and common ratio r = 10/20 = 5/10 = 0.5.
nth term = a1 r^(n -1) so here:
9th term = 20(0.5)^(9-1)
= 20(0.5)^8
= 0.078125.
