Area = Length x Width = 100 x 22 = 2200 ft²


Length of a square with area 2200 ft² = √2200 = 46.9 ft


Perimeter of the square = 46.9 x 4 = 188 ft (nearest feet)

A line includes the points (10, -10) and (1,8). What is its equation in slope-intercept form?
Anettt [7]

Answer:

y=-2x+10

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(8-(-10))/(1-10)

m=(8+10)/-9

m=18/-9

m=-2

------------------

y-y1=m(x-x1)

y-(-10)=-2(x-10)

y+10=-2x+20

y=-2x+20-10

y=-2x+10

6x – 4y = -5<br>4x + 5y = -11​
kipiarov [429]

Answer:

x= -1.5, y= -1

Step-by-step explanation:

6x= -5+4y

x= (-5+4y) / 6

4((-5+4y) / 6) + 5y = -11

4(-5+4y) + 5*6y = -11*6

-20+16y+30y= -66

16y + 30y = -66+20 = -46

y(16 + 30) = -46

y= -46 / (16 + 30)

y= -46 / 46

y= -1

x= (-5+4(-1)) / 6

x= (-5-4) / 6

x= -9 /6

x= -1.5
