distance formula:
d = √[( x₂ - x₁ )² + ( y₂ - y₁ )²]
Given:
x₂ = 12
x₁ = 5
y₂ = 3
y₁ = 7
Solve:
d = √[( 12 - 5 )² + ( 3 - 7 )²]
d = √[( 7 )² + ( -4 )²]
d = √[ 49 + 16 ]
d = √[ 65 ]
d ≈ 8

A line parallel to y=1/3 x+2
Answer:
y = 1/3x
Step-by-step explanation:
If you use the form y = mx + b, all you need to create a parallel line is to have the same slope. So, we can just disregard b and write an equation with a slope of 1/3. You can add or subtract any number to that if you want.

2y < y + 2
Explanation:
Subtract y from both sides. This will isolate y.
2y < y+2
2y-y < y+2-y ... subtract y from both sides
y < 2

DeShawn and Totsakan are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of shiny wrapping paper. DeShawn sold 12 rolls of plain wrapping paper and 1 roll of shiny wrapping paper for a total of $59 . Totsakan sold 6 rolls of plain wrapping paper and 8 rolls of shiny wrapping paper for a total of $112. Find the cost each of the rolls of plain wrapping paper and one roll of shiny wrapping paper .
9514 1404 393
Answer:
plain: $4shiny: $11Step-by-step explanation:
Let p and s represent the costs of plain and shiny rolls of paper, respectively. The given sales let us write two equations in these two unknowns.
12p +1s = 59 . . . . . DeShawn's sale
6p +8s = 112 . . . . . Tatsakan's sale
Multiplying the second equation by 2 and subtracting the first, we have ...
2(6p +8s) -(12p +s) = 2(112) -(59)
15s = 165 . . . . . . . . . . . . . . . . . . . . . simplify
s = 11 . . . . . . . divide by 15
Substitute into the second equation to find p.
6p +8(11) = 112
6p = 24 . . . . . . . . subtract 88
p = 4 . . . . . . . . . . .divide by 6
A plain roll costs $4; a shiny roll costs $11.

What I s the sum of the measures of the interior angles of a 13-sided polygon?
Answer:
What is the sum of the measures of the interior anles of a convex 13-gon? There is a formula... the sum of the measures of the interior angles of a convex n-gon is (n-2)180 degrees. For a triangle, n=3, so it's (1)180=180 degrees.
Step-by-step explanation:
180(n-2)
n=number of sides
from question, number of sides=13
substitute 13 into the equation given above
180(13-2)
180(11)
