When comparing x^2 + 10 and x + x + x equals to:
x^2 +10 is greater than x + x + x when x = -5
Because -5^2 + 10 = 25 + 10 = 35
and -5 + -5 + -5 = -15
So, 35 > -15
it would depend how much you actually used, but you would take the amount you used and divide it by the total amount of yarn. so if the yarn was 4m long and you used 2m then it would be 2/4 which is 0.5 which is also 50%, so half the yarn was used.
Answer:
10.11 feet
Step-by-step explanation:
Let H ft be the elephant's height and x ft be the initial distance from naturalist to the elephant.
1. Naturalist takes a view to find the a 22 degree angle of elevation, then
2. Naturalist moves backwards from the elephant pacing off a distance of 27 feet, the distance from naturalist to the elephant becomes (x+27) ft. He takes a second view and determines a new angle of elevation of 11 degrees. Then
3. Solve the system of two equations:
Then
Answer:
y = -2x + 2
Step-by-step explanation:
(-4-8)/(3-(-3)) = -12/6 = -2
-4 = -2(3) + b
-4 = -6 + b
b = 2
The answer to 1/4x - 6 = 3/5 is x = 132/5, or if you want to simplify it to a mixed fraction, it'd be 26 2/5. Here are the steps:
1/4x - 6 = 3/5
+6 +6 Add 6 to each side to isolate the variable x.
1/4x = 6 3/5
(4)1/4x = 6 3/5(4) Multiply by 1/4's reciprocal (4), to isolate the variable x.
x = 33/5 (4)
x = 132/5
x = 26 2/5
