Answer:
25/28
Step-by-step explanation:
1 1/4=5/4
1 2/5=7/5
------------
(5/4)/(7/5)
(5/4)(5/7)
25/28
Your answer is 5.
You can think of it as 7-2 because -2 is less than zero so you would have to subtract it from 7.
Answer:
1) 2x-5 2) -10/x^2
Step-by-step explanation:
Use power rule and constant rule for the first one:
1) f(x)=x^2-5x^1+1 (x^n)'=nx^(n-1) and (c)'=0
f'(x)=2x^1-5(1)x^0+0
f'(x)=2x-5(1) x^0=1
f'(x)=2x-5
Use just power rule for last one after a rewrite
2) f(x)=10/x
f(x)=10x^(-1) now use power rule
f'(x)=-10x^(-2) =-10/x^2
Answer:
The answer to your question is:
p₁ = - 2 + 
p₂ = -2 -
Step-by-step explanation:
p² + 4p = -6
p² + 4p + (2)² = - 6 + (2)²
(p + 2)² = - 2
p + 2 = ±
p = -2 ±
p₁ = - 2 + p₂ = -2 -
