Answer:
F(x)=2x^2
Step-by-step explanation:
Basically, a quadratic function has x^2 in it (standard form ax^2+bx+c with non-zero a). The others have x^3, -x, x^4, etc., which clearly are NOT x^2.
Answer:
Step-by-step explanation:





Answer:
less than/equal to -2
Or, greater than/equal to 2.5
Step-by-step explanation:
2x² - x - 10 ≥ 0
2x² - 5x + 4x - 10 ≥ 0
x(2x - 5) + 2(2x - 5) ≥ 0
(x + 2)(2x - 5) ≥ 0
Roots: -2, 5/2
x《 -2 or x》5/2
Answer:
(2,3)
Step-by-step explanation:
The given system is
y=3x-3
y=2x-1
We equate both equations and solve for x.

Group like terms to get:


We put x=2 into y=3x-3 to get:

As an ordered pair the solution is (2,3)
Hey!!
here is your answer >>>>
If there are 8 students, and who have 3/4 the cake to share equally, we will have to divide 3/4 with 8.
which is( 3/4)/(8)
Now, we will have to take a reciprocal, we get,
(3/4)(1/8)
which is 3/32
which is
Each student gets, 3/32 of the cake!
Hope my answer helps!
