Answer:
Domain: (-∞,∞)
Range: -1
Step-by-step explanation:
Domain means the x-coordinates covered:
(-∞,∞)
Range means the y-coordinates covered:
Only -1 because there are no other existing y-coordinates.
Answer:
The x variable has an exponent of 2.
Step-by-step explanation:
X variables with exponents of 2 mean they are quadratic.
Divide the area with the length ( 9 feet long)
Area: 63/9
= 7 feet long
7*9=63 ft 2
Answer: 7 feet long
Answer:
3/5
Step-by-step explanation:
7/15 + 2/15 = 9/15
both 9 nad 15 are divisible by 3
9/15 = 3/5
We know that the perimeter of a rectangle can be represented by the expression 2l +2w, where l represents the length of the rectangle and w represents the width of the rectangle.
If we substitute in the values given in this problem, we get the expression:
2(2x+6) + 2(x)
Another equivalent expression we can use to express the perimeter is w + w + l + l.
If we substitute in the values given in this problem into this expression, we get:
x + x + 2x + 6 + 2x + 6
Overall, we know that these expressions are equivalent and represent the same value (the perimeter of the rectangle), because if you combine like terms, both expressions simplify to 6x + 12.
Hope this helps!
