Answer:
x = 2 and y =
Step-by-step explanation:
y = 2x - 1
y = -x + 5
2x - 1 = -x + 5
2x + x = 5 + 1
3x = 6
x = 6/3
x = 2
y = 2(3)-1
y = 5
1) Answer: 
<u>Step-by-step explanation:</u>
f(x) = 6x⁻¹
f'(x) = -6x⁻²
= 
f'(-2) = 
= 
= 
*****************************************************
2) Answer: 
<u>Step-by-step explanation:</u>
f(x) = -9x⁻¹
f'(x) = 9x⁻²
= 
f'(6) = 
= 
= 
Answer:
D
Step-by-step explanation:
Slope of -2 that's going through y=1
so y=-2x+1
It would be D: 181
3 17
---- = ------
32 X
Then you would cross multiply and divide.
