A parabola has a vertex of (5,4) and goes through the point (6,-10)
natali 33 [55]
Y = -2(x-5)^2 + 4

Note: vertex form is 0, f(x), y, or nothing= a(x-h)^2 + k
The opposite of the x value of the vertex is h
The y value value of the vertex is k.


Find a. Plug in (6,-10)

-10 = a(6-5)^2 + 4
-10 = 1a + 4
-10 = 5a
a = -2

11(n – 1) + 35 = 3n<br><br> n = –6<br> n = –3<br> n = 3<br> n = 6
vlada-n [284]

Answer:

n =  -3

(second option listed)

Step-by-step explanation:

first, we will distribute the 11 (n-1)

11 (n - 1) + 35 = 3n

11n - 11 + 35 = 3n

Now, we will combine -11 and 35 (because they are like terms)

11n + 24 = 3n

Now, to isolate x as a positive, I will subtract 3n from both sides

11n + 24 = 3n

- 3n           - 3n

8n + 24 = 0

Now, I will subtract 24 from both sides to isolate n

8n + 24 = 0

      - 24    - 24

8n = -24

Now, we will divide both sides by 8 to find "n"

8n  = -24

÷8       ÷8

n = -3

This means that n is equal to -3

(n =  -3)

2 thousands 7 tens divided by 10 equal
Shkiper50 [21]

The answer is 207 or 2 hundreds 7 ones in unit form or two hundred seven in word form.

<h3>Further explanation</h3>

2 thousands 7 tens are a unit form. The standard form is 2,070.

Explanations and an example of questions about the four types of number forms can be found at brainly.com/question/4725342.

The key problem is working out the value of 90,000 divide by 10. This is a division operation.

\boxed{2,070 \div 10 = ?}

Option-1

Both numbers are divided by 10.

\boxed{2,070 \div 10 = 207 \div 1}

The result is

\boxed{2,070 \div 10 = 207}

Option-2

Division operations can be written as fractions, like this.

\boxed{\frac{2,070}{10} = ?}

The numerator and denominator are both divided by 10, or 'cross out a zero from both'.

\boxed{\frac{207}{1} = ?}

The result is

\boxed{2,070 \div 10 = 207}

- - - - - - -

If x is divided by y equals z, then x is equal to y multiplied by z.

\boxed{If \ x \div y = z \ or \ \frac{x}{y} = z, then \ x= y \times z}

Let's prove it!

\boxed{If \ 2,070 \div 10 = 207 \ or \ \frac{2,070}{10} = 270, then \ 2,070 = 10 \times 207}

This is proven.
