What letter stays the same when reflected over the x-axis

valina [46]

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.p explanation:

Misha wrote the quadratic equation 0=-x2+4x-7 in standard form. what is the value of c in her equation

Masteriza [31]

Answer:

Final answer is c=-7.

Step-by-step explanation:

Given equation is $0=-x^2+4x-7$ .

Now question says that Misha wrote the quadratic equation 0=-x2+4x-7 in standard form. Now we need to find about what is the value of c in her equation.

We know that standard form of quadratic equation is given by $ax^2+bx+c=0$ .

compare given equation with the standard form, we find that -7 is written in place of +c

so that means +c=-7

or c=-7

Hence final answer is c=-7.

Need help with this question

Lilit [14]

Answer: 30

Step-by-step explanation: To solve this problem, we're going to have to use the Pythagorean theorem...

a² + b² = c²

24² + 18² = c²

576 + 324 = c²

c² = 900

$\sqrt{900}$

30 = c

I hope this helps!
