Answer:
16/19
Step-by-step explanation:
A: the independent variable is the number of soccer games you officiate
B: the dependent variable is your earnings
C: e = earnings; s = soccer games
e = 15s
Step-by-step explanation:
6x - 3x^2 + 2x^2 -2x = 5x^2 + 15x
4x -x^2 = 5x^2 + 15x
-11x - 6x^2 = 0
-6x^2 - 11x = 0
use the quadratic formula
(-b±√(b²-4ac))/(2a)
(4, ?) is on 8x - 3y = -10
The ? is the missing y coordinate. (4, y) satisfies 8x - 3y = -10
8x - 3y = -10. From point (4, y), we would replace x = 4 in the equation below. y remains the unknown.
8*4 - 3y = -10
32 - 3y = -10
-3y = -10 - 32
-3y = - 42
y = -42/-3
y = 14
So the coordinate is (4, 14)
D because of the vertical line test. The c input 2 has two different out puts meaning that it is not a function
