Answer: 1) A
2) yes
Step-by-step explanation:
Answer:
Domain is all real numbers greater than or equal to 7. Range is all real numbers greater than or equal to 9.
Step-by-step explanation:
The domain is possible x-values while the range is possible y-values. This question look like
The domain of square root function cant have a the radical inside being a negative number because we can't take the sqr root of a negative number and graph it on a cartisean plane We can take the sqr root of 0 . So we set x-7=0. And which x=7 so the domain is all real numbers that are equal to or greater than 7. The range of a sqr root function can only yield any positive y-values. So we must find the lowest point of it. Since the lowest x value we can possible use is 7 we plug it in
which equals 9. So the range is all real numbers greater than or equal to 9.
The relation between the width and the length is:
l = 3w + 1 --- (1) Perimeter = 2w + 2l --- (2) Put (1) in (2) » Perimeter = 2w + 2(3w+1) » Perimeter = 2w + 6w + 2 Perimeter = 8w +2
3 because length times width = area right. so 3x3=9.
