Set up a ratio between the small triangle and the large one.
AD/ AE = AC / AB
(8 + 2)/8 = 10 / x
10/8 = 10/x Cross multiply
10x= 80 Divide by 10
x = 8
Answer 4th one down. <<<<====
You can choose from the first letter 7 ways. For each of those 7 ways to choose the first letter, you can chose the second letter also. As well as the 3rd, 4th, 5th, 6th, and 7th. So you would multiply or use powers (7x7x7). Which would give you the answer of 343. There is 343 ways that "algebra" can be arranged.
(I'm in the 7th grade)
<span>1.25 = 0.75x + 50
0.75x = 1.25 - 50
0.75x = -48.75
x = -48.75 / 0.75
x = 65</span>
Answer:
D. They have the same x-intercept but different end behavior as x approaches infinity
Step-by-step explanation:
A careful comparison reveals the g(x) values in the table are 1/2 the y-values in the graph. The x-intercepts are the same, but the y-intercepts and end behavior are different.
When it comes to this "vertex form" type of expressions, the cheap way to get the vertex is, set the grouped terms to 0, namely
x - 5 = 0
x = 5
well, if we set x = 5, x - 5, turns to 0, and that happens when x = 5, therefore, the vertex is
| x - 5 | + 10
| (5) - 5 | (+ 10) is at ( 5 , 10 )
