The factored form of a quadratic equation is y=(2x+1)(x-5), and the standard form is y=2x²-9x-5. which of the following statements accurately describes the graph of y?
a) the x-intercepts are -1 and 5, and the y-intercept is -5.
b) the x-intercepts are -1/2 and 5, and the y-intercept is -5.
c) the x-intercepts are -1/2 and 5, and the y-intercept is 5.
d) the x-intercepts are 1 and -5, and the y-intercept is -5.

Step-by-step explanation:

The intercept form of a quadratic equation y = ax² + bx + c:

We have the equation:

Therefore

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
