Answer:
The perimeter of the triangle is 
Step-by-step explanation:
Let

we know that
The perimeter of triangle is equal to

the formula to calculate the distance between two points is equal to
step 1
Find the distance AB

substitute in the formula
step 2
Find the distance BC

substitute in the formula
step 3
Find the distance AC

substitute in the formula
step 4
Find the perimeter

substitute the values

Y=3.5x
Pts are (1,3.5),(2,7),(3,10.5)
Answer:
x = 12
Step-by-step explanation:
24 = 3x - 12 (opposite sides of a parallelogram are equal)
24 + 12 = 3x
36 = 3x
36/3 = x
12 = x
Your answer is D.
Will always be x2 and y2 starting off
U have a solid line...meaning there is an equal sign in the problem
u have a y int of -1 (the y int is where ur line crosses the y axis)
u have a slope of : 1
it is shaded below the line...so it is less then
so ur inequality is : y < = x - 1 <==
