The answer is 14
-18/6 is -3. add that to 17 and you get 14.
We have a right triangle with
a = one leg = 28
b = other leg = 21
c = hypotenuse = 5x
use the pythagorean theorem (a^2+b^2 = c^2) and solve for x
a^2+b^2 = c^2
28^2+21^2 = (5x)^2
784+441 = 25x^2
1225 = 25x^2
25x^2 = 1225
(25x^2)/25 = 1225/25
x^2 = 49
sqrt(x^2) = sqrt(49)
|x| = 7
x = 7 or x = -7
Since the hypotenuse has length 5x meters, this means
5x = 5*7 = 35
or
5x = 5(-7) = -35
Toss out the negative length as it makes no sense.
The only value of x is x = 7
Therefore the final answer is x = 7
Answer:
67
Step-by-step explanation:
(4*100)/6
=400/6
=66.67
Round to get 67
5 2/7 is the answer.
37÷7= 5 remainder 2. Then it will be 5 2/7.
As <em>x</em> approaches -1 from the left, the graph of <em>f(x)</em> leads you to the point (-1, 3), so the limit from the left is 3.
As <em>x</em> approaches -1 from the right, the graph leads to the point (-1, -3), so the limit from the right is -3.
The one-sided limits do not match, so the two-sided limit does not exist.
But <em>f(x)</em> is still defined at <em>x</em> = -1; this is indicated by the point (-1, -1). So <em>f</em> (-1) = -1.
