The y-intercept is where the line crosses the y-axis so we can narrow it down to c and d because in the y-intercept x is 0 it crosses at -9 so it is c have a good day

$c \: is \: the \: answer$
The Y intercept of the graphed function would be,
(0,-9) because the graph (which is a function) intercepts on (0,-9) therefore the function's y-intercept is,
$b = - 9$

35(month) +35(month) =70(joining fee). 70+70=140. that's two months at the first gym.

the second gym is also 140 for the two months because each month is $70. and 70+70=140

What are the zeros of the parabola whose equation is y = x2 + 8x + 15

Answer:

(1) -5 and -3

Step-by-step explanation:

Descarte's rule of signs tells you the lack of sign changes among the coefficients means there are no positive real roots. That eliminates all answer choices except the first one.

If you want to go to the trouble, you can factor the equation:

y = (x +3)(x +5)

These factors are zero when x = -5 and x = -3.
