Cost of the current plan: $175
Number of devices: x
Cost of the new plan: $94+($4.50/device)x
Cost of the new plan is less than the current plan:
$94+($4.50/device)x<$175
Solving for x:
$94+($4.50/device)x-$94<$175-$94
($4.50/device)x<$81
(device/$4.50)($4.50/device)x<(device/$4.50)($81)
x<18 devices
Please, see the attached file.
Thanks.
Answer:
y = -1/3x -2
Step-by-step explanation:
Slope intercept form of a line is
y= mx+b
We need to solve for y
1/3x +y = -2
Subtract 1/3x from each side
1/3x -1/3x +y =-1/3x -2
y = -1/3x -2
Answer:
Option D. The circumference
Step-by-step explanation:
A). Area 'y' of square with side 'x' will be represented by
y = (Side)²
y = x²
Since the degree of this polynomial function is 2, It's a quadratic equation.
B). Area of the circle = πr²
y = π(x)²
Since the degree of this polynomial function is 2, It's a quadratic equation.
C). Volume of a cube = (Side)³
y = x³
Since the degree of this polynomial function is 3, It's not a linear function.
D). Circumference of the circle = 2πr
y = 2π(x)
Since the degree of this polynomial function is 1, it's a linear function.
