Just as how you would teach multiplication to any child in the beginning. There is 1 set of 2 pencils. 1 * 2 = 2 pencils. There are 2 sets of pencils. 2 * 2 = 4 pencils. You would apply the same concept to 8/10 that any number multiplied by 1 is itself.
The formula for an arithmetic sequence is An=A1+(n-1)d.
Using this knowledge, you can set up the equation easily to be An=1+(12-1)-5
You then simplify this to 1-55 using PEMDAS, giving you the answer for the twelfth term being -54, you then do this for every term if you want (or you could just subtract 5 by the terms after 14 till you get to -54. After all that, you add the twelve terms up to get -319 as your final answer
To find x- intercept the zero so substitute y=0
0=-x+1
X=1 thqt should be your answer
Hope this helped
Answer: x=1
Answer:
Therefore the Distance across the Pond is

Step-by-step explanation:
Given:
Triangle are Similar
AB = 90 ft
AC = 170 ft
BD = 207 ft
DE = x
To Find:
x = ?
Solution:
In Δ ABC and Δ DBE
∠A ≅ ∠D …………..{ measure of each angle is 90° given }
∠ABC ≅ ∠DBE ……….....{Vertical Angle Theorem}
Δ ABC ~ Δ DBE ….{Angle-Angle Similarity test}
If two triangles are similar then their sides are in proportion.
Substituting the values we get

Therefore the Distance across the Pond is
