Answer:
14
Step-by-step explanation:
you add them all up and divide by how much there are
(10+11+12+13+14+15+16+17+18)=126
(126/9)=14
Vertex Form of Quadratic Equation - MathBitsNotebook(A1 - CCSS Math) f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. FYI: Different textbooks have different interpretations of the reference "standard form" of a quadratic function...:)
The answer to this question is answer choice C.
For the SSS postulate, we need 3 pairs of congruent sides. However, in the image, there are only 2 pairs.
The missing pair in the image is AC and DF. If those are congruent, the triangle can be proven congruent by the SSS postulate.
Hope this helps! :)

The equation of the line from give points is y = 2/3x - 5/3.
According to the statement
We have given that the two points which are (-2,-3) and (4,1)
And we have to find the equation of a line that passes through the given points.
So,For this purpose,
First, we need to determine the slope of the line. The slope can be found by using the formula:
Where
m is the slope and
Substituting the values from the points in the problem gives:
m = 1 + 3 /4 + 2
m = 4/6
m = 2/3.
And then
Now, we can use the point-slope formula to find an equation for the line. The point-slope formula states:
Put the values in it then
y - (-3) = 2/3 (x-(-2))
y +3 = 2/3 (x +2)
3y + 9 = 2x + 4
3y - 2x = 4 -9
3y -2x = -5
3y = 2x - 5
y = 2/3x - 5/3.
So, The equation of the line from give points is y = 2/3x - 5/3.

Answer:
Yes
Step-by-step explanation:
In a triangle the sum of two of its sides is major than the the other side
9+4 > 11
11 + 4 > 9
11 + 9 > 4
