Let x = number of South American animals
Let y = number of African animals
x=45+1/2y
x=172
Solve for y
Answer:
343
Step-by-step explanation:
7 * 7 * 7
7 * 7 = 49
49 * 7 = 343
(dz/dx)= (-e+4)(4pi)sin(4pi*t)
6(4x+5)=3(x+8)+3
24x+30 = 3x+24+3
24x-3x = 24+3-30
21x = -3
x = -3/21 = -0,14
Hi there! The answer is D.
Function
f(x) = 7x - 6.
To find the inverse we need to switch the places from x and y.
y = 7x - 6
x = 7y - 6
-7y = -x - 6
7y = x + 6
y = (x + 6) / 7
