Answer: x=−3 or x=13
Step-by-step explanation:
Step 1: Subtract 39 from both sides.
x2−10x−39=39−39
x2−10x−39=0
Step 2: Factor left side of equation.
(x+3)(x−13)=0
Step 3: Set factors equal to 0.
x+3=0 or x−13=0
x=−3 or x=13
Check the picture below.
bear in mind that, a perpendicular line stemming from the right-angle like so, creates three similar triangles, a
large one, containing the other two smaller ones, a
medium and a
small.
so.. .we can just use the medium and small proportions.
solve for "x".
Answer:
21.5
Step-by-step explanation:
The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
Hopefully this helps:) Please mark me brainiest:)
The possible values of x for the following functions are values on real number except 0 and 1
<h3>Domain of a function</h3>
The domain of a function are the values of the independent variable for which it exists.
Given the function below
f(x)=2-x/x(x-1)
The function does not exist at the. point where the denominator is zero. From the function given, the function does not exist when;
x(x -1) = 0
x = 0 and x = 1
Hence the possible values of x for the following functions are values on real number except 0 and 1
