Answer:
AB = 13 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = B(- 5, 12) and (x₂, y₂ ) = A (0, 0)
d = 
= 
= 
= 
= 13
Answer:
b. (2, 5, 3)
Step-by-step explanation:
Trying the offered choices seems the fastest way to find the answer. The second choice works in all equations, hence is the solution.
Another strategy you can use is to see if the equations are dependent. Here, it looks like adding twice the third equation to the other two eliminates at least the x- and y-variables. If that eliminates z, then there are infinite solutions. Instead, it gives the equation ...
7z = 21
z = 3 . . . . . divide by 7
This answer is consistent with choice B, confirming that answer and eliminating the other choices.
Answer:
B
Step-by-step explanation:
your answer should be B because isosceles triangles always have 2 equal sides :))
You would need the table to figure this problem out, but here we go!
15000×.018= 270
15000×.020= 300
15000×.023= 345
270+300+345= $915
