Answer:
a. -216, 0 real roots
Step-by-step explanation:
The discriminant of ...
ax² + bx + c = 0
is ...
d = b² -4ac
When we put your equation into the standard form shown above, we get ...
7n² +8n +10 = 0
Then we can identify a=7, b=8, c=10. The discriminant is then ...
d = 8² - 4·7·10 = 64 -280 = -216
___
The interpretation of the discriminant is ...
- < 0; no real roots (2 complex roots)
- = 0; one real root (multiplicity 2)
- > 0; 2 real roots
Your discriminant is -216, so there are 0 real roots.
30-24=6 6/30=0.2
0.2x100=20

Hello There!!
Step-by-step explanation:
1)x+3y+−3y=9+−3y
x=−3y+9
2)−2x+y+−y=−4+−y
−2x/-2=−y−4/-2
x=1/2 y+2
hope this helps,have a great day!!
