closed dot is if the number is part of the solution so if it is equal to
and
use open if it is not part of solution as in if it is greater than or less than
so for your picture x greater or equal to -2 it would be a closed dot
Answer:
Step-by-step explanation:
Use the slope formula
(x2-x1)/(y2/y1)
substitute the values
(1-10)/(9-7)
solve
-9/-2
simplify
9/2 or 4.5
Answer:
Not a function
Step-by-step explanation:
(-4,9), (-4,0) : one input (-4) with 2 output -9 , 0
The aswer would be B because you have to divide a couple numbers to get 20in.
Answer: Yes. The area is 1089 square feet.
Step-by-step explanation:
For a square, all the sides are equal: L = W
Hence, the perimeter of a square = 4 × L
Perimeter = 4L
132 = 4L
132 ÷ 4 = L
33 = L = W
Area of a square with 33 feet sides = L × L = 33 × 33 = 1089
1089 > 1000
