Question

Dau coroana va rooog!!!

Answer 1

Originea sistemului de axe este O(0;0) => f(0)=0

f(0)= 0-7d-8 = 0 | +8

-7d=8

d= $-\frac{8}{7}$ = -1 $-\frac{1}{7}$

Sper ca te-am ajutat! :)

Answer 2

$\it O(0,\ 0)\in Gf \Rightarrow f(0)=0 \Rightarrow -7d-8=0 \Rightarrow -7d=8 \Rightarrow d=-\dfrac{8}{7}=-1\dfrac{1}{7}$
