<span> y = a(x – h)2 + k, where (h, k) is the vertex. in y = ax2 + bx + c (that is, both a's have exactly the same value). The sign on "a" tells you whether the quadratic opens up or opens down.</span>
A.Dose every point on the line
If sum of 2 shorter sides > longest side , then a triangle can be formed.
9.) 6 + 8 = 14 > 10; yes
10.) 7 + 8 = 15 > 10; yes
11.) 75 + 25 = 100 = 100; no
12.) 1 + 1 = 2 = 2; no
To find the vertex it the h and k.
For ex: 4(x+5) 7
Ur h is - 5 and ur k is 7
So the vertex is (-5,7)
Also u take the opposite what in the parenthesis, since it positive 5, it becames - 5.
Answer:
The top right graph.
Step-by-step explanation:
If you find the mean for all the graphs you get:
Graph 1: 7 Graph 2: 2
Graph 2: 7 Graph 4: 7
To find the mean you all all the numbers up and divide it by the number of data points for example heres the first graph:
8 + 8 +8 +8 +8 +8 +1 = 49 Add the data points
49 / 7 = 7 Divide by the total amount of points which is seven
