Answer:
20 units
Step-by-step explanation:
We are given that
On a coordinate plane , rhombus ABCD in which point A is at (1,1) and point B is at (-2,-3), point C is at (-5,1) and D is at (-2,5).
We have to find the perimeter of rhombus ABCD.
Distance formula : 
Using the distance formula
Side AB=
We know that sides of rhombus are equal
Therefore, AB=BC=CD=AD=5 units
Perimeter of rhombus=
Perimeter of rhombus=
Answer: 20 units
Answer:
25%
Step-by-step explanation:
X=(18.75*100)/75
The y intercept is what the y value is when x is 0.
Set X to 0 and solve:
-2/9(0) + 1/3
0 + 1/3 = 1/3
The y-intercept is 1/3
Answer:
-4
Step-by-step explanation:
We know it's a linear equation and the slope is a whole number. Using point slope form we will write the equation:
y - y1 = m (x - x1) in which y1 is -7, m is 3, and x1 is -1
y - (-7) = 3(x-(-1))
y+7 = 3(x+1)
y+7 = 3x +3
Change to slope-intercept form:
y = 3x + 3 - 7
y = 3x = -4
the y intercept is -4
