Answer:

x=-b/2a

Step-by-step explanation:

axis of symmetry is the line that across the vertex from a parabola(ax^2+bx+c).

The expression to find vertex is -b/2a

Thus, x=-b/2a is a vertical line that across the vertex aka the axis of symmetry.

Answer:

The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .

You cut a circular hole 1/4 -inch in diameter in a piece of cardboard. With the cardboard 30 inches from your face, the Moon fit

Stolb23 [73]

Answer:

The Moon's diameter is greater than $1,500$ miles

Step-by-step explanation:

we know that

$1\ mile=63,360\ inches$

$1,500\ miles=1,500*63,360=95,040,000\ inches$

$240,000\ miles=240,000*63,360=15,206,400,000\ inches$

by proportion

Find the Moon's diameter

Let

x-----> the Moon's diameter in inches

$\frac{x}{15,206,400,000}=\frac{0.25}{30}\\ \\x= 15,206,400,000*0.25/30\\ \\x=126,720,000\ inches$

Compare

$126,720,000\ inches> 95,040,000\ inches$

therefore

The Moon's diameter is greater than $1,500$ miles

The sum of two numbers is 20. One number is one less than twice the second number. What are the two numbers?

murzikaleks [220]

Answer: Hope this helps.

13, 7

Step-by-step explanation:

Number one is 13

Number two is 7

Well 7 x 2 = 14, 14-1 = 7, and 7+13 = 20 making the answers true.

I figured out this number by eliminating numbers, I started with 5, ended with 8 to make a range of the possible numbers. Since 5 was too low and 8 was too high I knew the number had to be either 6 or 7, so I did 7 and I got the answer.
