Answer:

<h3>           vertex form:    y = (x + 1)² - 3</h3><h3>           the vertex is minimum</h3><h3>           coordinates of the vertex:  (-1, -3)</h3>

Step-by-step explanation:

y=x^2+2x-2\\\\y=x^2+2x+1-1-2\\\\\bold{y=(x+1)^2-3}

a = 1 > 0  ← it means the parabla opens up, so, <u>the vertex is </u><u>minimum</u>

The vertex form is  y = a(x - h)² + k, where (h, k) is the vertex

So, from  y = (x + 1)² - 3   <u>the vertex is</u>:  (-1, -3)

Answer:

The answer is

p =  \frac{ - 3}{1000} n + 97

Step-by-step explanation:

We have the points (2000,91) and (5000,82)

Then

m =  \frac{91 - 82}{2000 - 5000}  =  \frac{ - 3}{1000}  \\ to \: find \: the \: b \\ 91 =  \frac{ - 3}{1000}  \times 2000 + b \\ b = 97 \\ then \: the \: equation \: is \:  \\ p =  \frac{ - 3}{1000} n + 97

Triangle ABC has perimeter 22cm
ASHA 777 [7]

9514 1404 393

Answer:

  not a right triangle

Step-by-step explanation:

The perimeter is 22, so we have ...

  AB +BC +CA = 22

  8 + 5 + CA = 22

  CA = 22 -13 = 9

If this is a right triangle, the sum of the squares of the short sides will be equal to the square of the long side.

  AB² +BC² = 8² +5² = 64 +25 = 89

This is not the same as ...

  CA² = 9² = 81

The triangle is not a right triangle.

_____

<em>Additional comment</em>

If you're familiar with a few Pythagorean triples, you know that a couple involving a side length 5 are (3, 4, 5) and (5, 12, 13). That is, (5, 8, 9) is NOT a Pythagorean triple, so you know immediately that those side lengths do not form a right triangle. (No calculation is necessary.)
