Answer:
Step-by-step explanation:
It's the vertex form of a quadratic equation of
The vertex is at (h, k).
k is minimum or maximum for value of h.
k - its value of y for x = h.
We have
[tex]k=2(8^2)-32(8)+56=2(64)-256+56=128-256+56=-72[/tex
Answer:
Step-by-step explanation:
(im presuming this is a triangle)
65 + 45 = 110°
angles in a triangle add up to 180°
180 - 110 = 70°
x = 70°
The equation is: (y+3)/(-1+3) = (x-5)/(3-5);
Then, (y+3)/2 = (x-5)/(-2);
Finally, y+3 = -x+5;
y = -x + 2;
Solution:
<u>Note that:</u>
- Triangle = 180°
- 5x + 130 + 3x + 2 = 180
<u>Simplify the equation to find x.</u>
- 5x + 130 + 3x + 2 = 180
- => 8x + 130 + 2 = 180
- => 8x + 2 = 180 - 130
- => 8x = 50 - 2
- => 8x = 48
- => x = 48/8 = 6
The value of x is 6.
Answer:
Perimeter = sum of length of all sides = 8 + 3 + 10 + 11 = 32
Area = (base1 + base2) x height/2 = (3 + 11) x 7/2 = 49
Hope this helps!
