Answer:
7/11
Step-by-step explanation:
All you need to do for reciprocals is flip the fraction so the denominator becomes your numerator.
Therefore the reciprocal of 11/7 is 7/11.
Answer:
x=31
<c = 93
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
<a +<b + <c = 180
35+ 52+3(x+2) = 180
Combine like terms
87+3(x+2) = 180
Subtract 87 from each side
87-87 +3(x+2) = 180-87
3(x+2) =93
Divide each side by 3
3(x+2)/3 = 93/3
x+2 = 31
Subtract 2 from each side
x+2-2 = 31-2
x = 29
Substitute x into the expression for angle c
<c = 3(x+2)
=3(29+2)
= 3(31)
=93
Answer:
5x^4 -7x^3-5x^2+5x+1
Step-by-step explanation:
Hey!
You would just add all the numbers up, and by making sure that you combine all like terms. In this case it is just 1-0 = 1 and so the solution would be the same as your question but with a 1 and you would get rid of the -0.
Hope this helps!
Rewrite the given quadratic equation in standard form: Kx 2 + 2x - 1 = 0
Discriminant = 4 - 4(K)(-1) = 4 + 4K
For the equation to have two real solutions, the discriminant has to be positive. Hence we need to solve the inequality 4 + 4K > 0.
The solution set to the above inequality is given by: K > -1 for which the given equation has two real solutions.
