The quadratic formula is one of the ways to find a solution to the quadratic equation, alongside graphing and completing the square. The quadratic formula can be represented as $x= \frac{-b \sqrt{ b^{2}-4ac } }{2a}$ where a is the squared value, b is the multiplied value, and c is the constant.

Which are all the solutions of 5sinθ-4=2sinθ-4, where 0≤θ≤2π

WINSTONCH [101]

5sinx-4 =2sinx-4
5sinx-2sinx= 4-4
3sinx=0
sinx=(0÷3)
sinx = 0
x = sin^-1 (0)
x= 0 degrees

And also x = (180- 0 ) = 180 degrees

so x; has 2 answers within the above given interval.

They are;

2(4.r + 3) = 7x+5<br><br> (SHOW WORK)

KatRina [158]

Answer: r=7x-1/8

Step-by-step explanation:

2(4r+3)=7x/2+5/2

4r+3=7x+5/2

4r+3-3=7x+5/2 -3

4r=7x+5/2 -3

4r/4= 7x-5/2/4 -3/4
