X= 8
Y= -7
If you use elimination:
–3y–4x=–11
3y–5x=–61
Add the two equations and get
–9x=–72
Divide by –9 on both sides
X=8
Substitute 8 in for x
–3y–4(8)=–11
Simplify
–3y–32=–11
Add 32 on both sides
–3y=21
Divide by –3 on both sides
Y=–7
You got to add like terms so 2x+3x =5x then you add the 7 to it and you get 12 then you take 8y and divide 12 and you should get 1.5
Answer:
1.
Step-by-step explanation:
First find the derivative of sin-1x.
This is a standard derivative and it is 1 /√(1 - x^2)
This is the slope of the graph at x.
Slope at x = 0 = 1 /√(1 - 0^2)
= 1/1 = 1,
I think that this is the right answers
