Finding the sol'n to f(x) - g(x) = 0 is the same as finding the solution of f(x)=g(x). You could do this analytically by setting the actual function f(x) = g(x) and solving for x (and then for y), or you could estimate the solution from the given graph. The two lines intersect at approx. x=-3.75, y=2.5.
8^1/3
8 is 2^3 so 8^1/3 = 2
The other expresssions don't give whole numbers.
A) w + 7 = L
B) w * L = 120
A) w = L -7 then substituting this into B)
(L-7) * L = 120
L² -7L = 120
L² -7L -120 = 0
Solving by quadratic Formula:
L1 = 15
L2 = -8
If length = 15, then width = 8
Answer:
85%
Step-by-step explanation:
1. Divide 100 by the maximum amount of students to get the percent value for every student (5% per student)
2. Subtract the number of students you know plays neither sport, leaving you with 17 students.
3. Multiply the remaining students by the percent percent value. 17 * 5 = 85%
(This takes into account that some students are playing both sports.)
<span>The reciprocal is shown as 1/x, or x-1. When we multiply a number by its reciprocalwe get 1. Example: 3 times 1/3 equals 1. Also called the "Multiplicative Inverse" See: Multiplicative Inverse.</span>
