Answer: C(x) = (8 php)*x + 50 php.
Step-by-step explanation:
In a linear equation:
y = a*x + b
a is the slope.
x is the variable
b is the y-intercept.
In this case, we have
The rent is 50 php fixed, plus 8 php per hour.
Then we will pay the 50php only one time, and it does not depend on the number of hours that we rent, then this is the y-intercept.
then if we rent the bike for x hours, we will pay a plus of x*8 php.
Then the total cost for x hours, C(x), will be
C(x) = (8 php)*x + 50 php.
Then the slope is 8 php, and the y-intercept is 50 php.
It’s a flip of the graph on the x-axis
Therefore f(x) = - x^2 (NOT IN PARENTHESIS that would be a reflection on the y axis)
It’s a shift 4 y values down therefore
g(x) = - x^2 - 4

Firstly, look at photo
Then, choose a point: (3, -5) is mine
(x0, y0) = (3, -5)
y + 5 = -3(x-3)
answer is B, Hope this helps ^-^
Answer:
Step-by-step explanation:
1) D
2) B
3) no solution
y ≤ 0.5x - 4 is area C including the red line
y ≥ 0.5x + 5 is area A including the blue line
