Answer:-4
Step-by-step explanation:
Subtract 5 from each side, which leaves you with 3x=-12. Then divide each side by 3. Then that leaves you with x=-4
Answer: the equation is
5x^2 -30x - 25
Step-by-step explanation:
A quadratic equation is one in which the highest power of the unknown is 2.
The general form of a quadratic equation is expressed as
ax^2 + bx + c
Where c is a constant and a is the leading coefficient
Assuming we want to write the quadratic equation in x, from the information given, the given roots are 5 and 1 and the leading coefficient is 5. We will just multiply the expression by the leading coefficient.
Therefore, the linear factors of the quadratic will be (x-5) and (x-1)
With the leading coefficient as 5, the equation becomes
5(x-5)(x-1)
= 5(x^2 - x - 5x + 5)
= 5(x^2 - 6x + 5)
= 5x^2 -30x - 25
Equation of circle at center (h,k) is given by

Given that center is at (5,0) that means h=5 and k=0
plug both values into above formula

...(i)
Given that circle passes through point (1,1) so it will satisfy above equation




Now plug this value of r^2 into equation (i)
which best matches with choice C
Hence
is the final answer.
The answer would be c)x+3 because if you substitute 1 for x, the expression would be 1+3 and it comes out as 4. Also, if you substitute 4 for x the expression would be 4+3 which comes out to 7
