I think the answer is A i’m sorry if it’s wrong i’m not for sure.
Answer:
2 non real solutions.
Step-by-step explanation:
We need to use discriminant,
for ax²+bx+c=0
The discriminat is b²-4ac
If the discriminant is,
→ less than 0, then 0 real solutions
→ equal to 0, then 1 real solutions
→ more than 0, then 2 real solutions
Given that,
7x²−4x+3=0
a=7, b=-4, and c=3
→ (-4)²-4(7)(3)
→ 16-84
→ -68
You can see this is less than 0, then non real solutions. [2 nonreal solutions]
Answer:
-3.7 > -3.1
Step-by-step explanation:
Because -3.1 more close to 0 so is supposed to be bigger than -3.7
Answer:
= -x^2 -x +6
D: all real values
Step-by-step explanation:
f(x) = 4-x^2
g(x) = 2-x
f+g = 4-x^2+ 2-x
Combine like terms
= -x^2 -x +4+2
= -x^2 -x +6
The domain is what values can x take
D: all real values
We are taking one quarter of the 2/5 of the students who play sports.
one quarter of 2/5 is 2/20 or 1/10.
