< 7 ==> 7 - 5 ==> 2
Pythagorean Theorem: C^2 = A^2 + B^2, or A^2 + B^2 = C^2
< AD <^2 ==> 2^2 + 18^2
< AD <^2 ==> 4 + 324
< AD <^2 ==> 328
< AD ====> 18.1
Hence, The Answer: Letter Choice, (A), 18.1
Hope that helps!!!! : )
Answer: It's going to be a 3x2. Im assuming its [ 5 10 on the first row, second row would be -2, -4, then the bottom row would be 1, 2] Hope I helped!
Step-by-step explanation:
10x^2y^-2 = 10 x (-1)^2 x (-2)^-2 = 10 x 1 x 1/4 = 10/4 = 2 1/2
let's recall that the domain of a set is always the list of all x-coordinates in each pair.

Y=mx+b
m=(325-180)/(9-4)
m=145/5
m=29
y=29x+b, using point (4,180) we can solve for b
180=29(4)+b
180=116+b
64=b, so the line is:
y=29x+64
Now the standard form of a line is ax+by=c so:
-29x+y=64 (by convention the coefficient of x should be positive so)
29x-y=-64
...
We can use the point-slope form we found earlier...
f(x)=29x+64
...
This is just a line so you can use any two points to graph it.
Connect (1,93) to (2,122) and extend upward and to the right as far as you please. The x-axis should be labeled "days" and the y-axis as "dollars".
