Answer:
500-25w
200
Step-by-step explanation:
Answer:
b. (3,0)
e. (5,-6)
f. (2,1)
Are solutions to the system of inequalities
Step-by-step explanation:
b. (3,0)
0 ≤ -2(3) + 6
0 ≤ 0 is true
3 > 1 is true
e. (5,-6)
-6 ≤ -2(5)+6
-6 ≤ -4 is true
5 > 1 is true
f. (2,1)
1 ≤ -2(2)+6
1 ≤ 2 is true
2 > 1 is true
(f-g) (x) means to subtract g(x) from f(x)
F(x) = 2x^2 +3
g(x) = x^2
This becomes:
2x^2 + 3 - x^2 = x^2 +3
Answer:8sqrt 2 or sqrt 128
Step-by-step explanation:
We can use the Pythagorean Theorem. Since the ladder is leaning against the wall, it is the hypotenuse. It is also 4 feet away from the wall so 12^2-4^2=b^2 b^2=128 so b=8sqrt 2 or sqrt 128.
Density is the degree of compactness of a substance. It is the degree of consistency measured by the quantity of mass per unit volume. It is the relationship between the mass of the substance and the amount of space it takes up. I hope it helps.
