Answer:
x≤-3 2 ≤x<7
Step-by-step explanation:
(x^2+x-6) /(x-7) ≤0
Factor the numerator
(x+3)(x-2) / (x-7)≤0
Critical points are
X =-3 X =2 X=7
We need to check the values when
x≤3 -3 ≤ x≤2 2 ≤x<7 x>7
(x cannot be 7 because then the denominator is zero)
and see when it is less than 0
Substitute a value in and see if factor is positive or negative
x≤-3
(negative)(negative) / (negative) = negative
-3 ≤x≤2
(positive)(negative) / (negative) = positive this range does not work
2 ≤x<7
(positive)(positive) / (negative) = negative
x>7
(positive)(positive) / (positive)
Answer:
Step-by-step explanation:
The comma is important here, otherwise "one third of a number n minus 7" is
Answer: 300
Step-by-step explanation: 70days is 10 weeks
Answer:
Perimeter is 100
Step-by-step explanation:
A^2 + B^2 = C^2
20^2 + 15^2 = C^2
200 + 225 = C^2
C^2 = 625
C=25
Perimeter is 100
To get this you would do the 25 X 4 = 100 yds
Hope this helps :)
