Answer:

Your numbers are +7, -9, and 25

Step-by-step explanation:

Reverse the values of -7 and +9

Then you get +7 and -9

And also take radius squared which is 25

So, (x--7)^{2} +(y-9)^{2}  = 25

Find the X Intercepts y=x^2-3x+6<br> PLEASE HELP ME

The x intrercepts is where the function crosses the x axis; In other words, it is where the output of the function is 0.

In a quadratic, you can start by factoring, if it’s unable to be factored then use the quadratic formula. Also, it is good to use the discriminate.

D= Discrimminate

D>0 2 real solutions

D=0 1 real solution

D<0 2 imaginary solutions.

The discrimminate is the equation/expression under the radical of the quadratic formula. With this formula, it’s not factorable. Using the discriminate it is also seen, as you’ll get a negative in the square root. This is imagenary because you cannot take the root of a negative value, which is why “i” is used to represent the square root of negative one.

2x + 12 = -2(4-2x)<br> X=10<br> X=-10<br> X=-5<br> X=5
Greeley [361]

Answer:

\boxed{x = 10}

Step-by-step explanation:

=  > 2x + 12 =  - 2(4 - 2x) \\  \\  =  > 2x + 12 =  (( - 2) \times 4) - (( - 2) \times 2x) \\  \\  =  > 2x + 12 =  - 8 - ( - 4x) \\  \\  =  > 2x + 12 =  - 8 + 4x \\  \\  =  > 2x - 4x + 12 =  - 8 \\  \\  =  >  - 2x + 12 =  - 8 \\  \\  =  >  - 2x =  - 8 - 12 \\  \\  =  >   \cancel{-} 2x =   \cancel{- }20 \\  \\  =  > 2x = 20 \\  \\  =  > x =  \frac{20}{2}  \\  \\  =  > x = 10
