Answer:
Step-by-step explanation:
Standard form is Ax+By = C. We need to get the x and y terms on the same side. To do this, we add 2x to both sides
y = -2x
y+2x = -2x+2x
y+2x = 0
2x+y = 0
So the answer is 2x+y = 0
This is in the form Ax+By = C where
A = 2
B = 1
C = 0
Answer:
30 students would have to go for the cost to be the same.
Step-by-step explanation:
Bus A: $40 + ($4 * 30) = $160
Bus B: $100 + ($2 * 30) = $160
Answer:
x-9 = 9 x-9 = -9
Step-by-step explanation:
(x - 9)^2 = 81
Take the square root of both sides
sqrt((x - 9)^2) = ±sqrt(81)
x-9 = ±9
x-9 = 9 x-9 = -9
Derivative are used to determine the nature of a function. The derivative of the function f(x) = 4x^2 is 8x
<h3>Derivative of a function</h3>
The formula for finding the derivative of a function is expressed as:
f'(x) = nax^n-1
Given the function expressed as:
f(x) = 4x^2
We are to find its derivative as shown:
f'(x) = 2(4)x^2-1
f'(x) = 8x^1 = 8x
Hence the derivative of the function f(x) = 4x^2 is 8x
