Answer:
y = 2x +1
Step-by-step explanation:
y=kx+1
Substitute the point into the equation
3 = k(1) + 1
3 = k+1
Subtract 1 from each side
3-1 = k
2 = k
y = 2x +1
The slope is 2 and the y intercept is 1
g(x) is the translation 9 units up of f(x) = |x|

Given :
The function f(x)=|x|
we need to translate f(x) , 9 units up to get g(x)
g(x) is the translation 9 units up of f(x)
when graph of f(x) is translated 9 units up , then we add 9 at the end
If f(x)=|x| is translated 'a' units up then its becomes |x|+a
g(x) is the translation 9 units up of f(x) = |x|
So , 
Write the answer in the given form a|x-h|+k

Answer:
25
Step-by-step explanation:
The only other number on the line with 625 is 25.
_____
(square root) = √(square)
Your picture shows a (square) of 625 and asks you for the (square root). The table shows the (square root) corresponding to the (square) of 625 is 25.

Answer: E) 8i</h3>
Explanation:
By definition, i = sqrt(-1)
Which means,
sqrt(-64) = sqrt(-1*64)
sqrt(-64) = sqrt(-1)*sqrt(64)
sqrt(-64) = i*sqrt(8^2)
sqrt(-64) = i*8
sqrt(-64) = 8i
On the second line, I used the rule sqrt(x*y) = sqrt(x)*sqrt(y). The fourth line used the rule sqrt(x^2) = x when x is nonnegative.
4A = E , A=E/4-----(1)
B/4=E , B=4E-------(2)
C+4=E, C=E-4------(3)
D-4=E, D=E+4------(4)
Substitute all values in 5th equation,
A+B+C+D=100 = E/4 + 4E + E-4+ E+4 =100
E/4 + 6E = 100
25E = 400
E=16 ANS....
