Step-by-step explanation:
Given: Foot length & shoe size in AP.
is foot length and n is shoe size.i.e., 
To find: Formula for Arithmetic sequence .i.e., 
From question,

Also, we know that
Now, consider

Thus using formula of
we get,

Therefore, The explicit formula for Arithmetic Sequence is 
Answer:
3x2-6x+1=0= 7/6
Step-by-step explanation:
3x2-6x+1=0
-6x=-7
than divide each term in -6x=-7 by -6 and simplify
x= 7/6
Answer:
f(x)= -|x + 1| + 1
Step-by-step explanation:
This is an absolute value equation, because it's that v-shape that let's us know it will be one. The standard form is
f(x)= a|x - h| + k, where h is the horizontal shift, k is the vertical shift, and a is the dilation factor.
We know that the graph is moved up one, because its vertex is at y = 1. So k = 1.
f(x)= a|x - h| + 1
We also know that it must be negative, because it's upside-down, so <em>put the negative outside the absolute value, not inside.</em>
f(x)= -|x - h| + 1
Lastly, the horizontal shift is left one, so we know that h = -1.
f(x)= -|x - -1| + 1
x minus a negative one equals x plus one, so
<u>f(x)= -|x + 1| + 1 </u>is our final answer.
Answer:
One solution
(2,0) is the point
Step-by-step explanation:
If the graphs of the equations intersect, then there is one solution that is true for both equations.
When the lines intersect, the point of intersection is the only point that the two graphs have in common, so the coordinates of that point are the solution for the two variables used in the equations.
The point of intersection is (2,0), because that is the point that both lines intersect at.
