Solve the equation show all steps
Answer:
x= 5
Step-by-step explanation:
4x-6=x+9
Move the -6 to the other side of the equation by adding 6 to each side.
4x-6 + 6 =x+9 + 6
4x = x+15
Now move the x on the right side of the equation to the left side of the equation by subtracting x from each side.
4x - x = x + 15 - x
3x = 15
Now to isolate the x, divide both sides of the equation by 3.
3x/3 = 15/3
x = 5
Check your answer by substituting x = 5 into the original equation:
4x-6=x+9
4(5) - 6 = 5 + 9
20 - 6 = 14
14 = 14 >>> so this answer, x=5, is correct.
Answer:
B) -3
Step-by-step explanation:
The zeros of the function are found easily from the factors. They are 6 and -12. The x-coordinate is halfway between them, at (6 + (-12))/2 = -6/2 = -3.
If you want a formula, consider a quadratic with roots (zeros) p and q. Then it factors as
... y = (x -p)(x -q)
The line of symmetry through the vertex is also the line of symmetry between the roots, so has x-coordinate:
... x = (p+q)/2
___
In your problem, you have p=6, q=-12, so x = (p+q)/2 = -6/2 = -3 is the line of symmetry and the x-coordinate of the vertex.
The vertex of a parabola is the minimum or the maximum point on the parabola
The x-coordinate of the vertex is -3
The equation is given as:
Open brackets
Differentiate
Set to 0
Collect like terms
Divide both sides by 2
Hence, the x-coordinate of the vertex is -3

The distance between Earth and its moons is 2.115 · 10⁵ km. Then the correct option is D.
Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Saturn’s rings span up to about (7.5 · 10⁻¹) of the distance between the Earth and its moons. If Saturn’s rings span up to (2.82 · 10⁵ kilometers).
The distance between Earth and its moons is calculated as,
⇒ 7.5 · 10⁻¹ x 2.82 · 10⁵
⇒ 0.75 x 2.82 · 10⁵
⇒ 2.115 · 10⁵ km
Thus, the correct option is D.
