Y = 8x - 2
y = 9x - 7
8x - 2 = 9x - 7
- 8x - 8x
-2 = x - 7
+ 7 + 7
5 = x
y = 8x -2
y = 8(5) - 2
y = 40 - 2
y = 38
(x, y) = (5, 38)
The answer is C.
Answer:
Step-by-step explanation:
The rate of change, slope, m is
m=(y2-y1)/(x2-x1), we have points (4,5) and (21,39) so
m=(39-5)/(21-4)
m=34/17
m=2
So the rate of change is 2
You just multiply by 2 as you can see
4×2=8
8×2=16 and so on
64×2=128 therefore 128 is the answer
<em>Answer:</em>
<em> 200.52 m²</em>
<em>Step-by-step explanation:</em>
<em>A = 12² + π·6²/2</em>
<em>= 144 + 36π/2</em>
<em>= 144 + 18×3.14</em>
<em>= 144 + 56.52</em>
<em>= 200.52 m²</em>
