The function f(x) = x2 + 10x – 3 written in vertex form is f(x) = (x + 5)2 – 28. What are the coordinates of the vertex?
Alexxandr [17]
Vertex form uses the following formula:

y = a(x-h)^2 + k

Identify the values of h and k in your function:

(x+5)^2 - 28
h = -5, k = -28

The vertex is found with the following point:

(h,k)
\text{Vertex: (-5, -28)}

The vertex will be found at (-5, -28).

Picture below<br> ..........................
masha68 [24]

Answer:

B) Multiply each side by 3

Step-by-step explanation:

This is how to solve for h

\frac{h}{3}+ 7 = 5           (First Step --> Subtract 7 from both sides)

\frac{h}{3} =  - 2             (Second Step --> Multiply both sides by 3 to cancel out the                                 denominator and to find just h)

h = -6

80,801 rounded to the nearest ten thousand
Dominik [7]
90,000 since you are rounding the whole number to ten thousand 90,000 is more closer than 80000. you have to round to the number it's asking so the rest of your answer after ten thousand should be left zero. therefore making the answer 90,000.
