Tomas wrote the equation y = 3x + 3/4. when sandra wrote her equation, they discovered that her equation had all the same solutions as tomas’s equation. which equation could be sandra’s?

step-by-step explanation:

tomas wrote the equation . when sandra wrote her equation, they discovered that her equation had all the same solutions as tomas’s equation.

tomas equation is  

to get an equation with same solution , we multiply by some number

to get sandra equation we multiply the equation by 2

(multiply whole equation by 2)

is sandra's equation

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.
