I see the question last and the 4 choices first.
Look at the points you have in the table with the question.
(0, 0), (4, 2), (9, 3)
The only graph that contains those three points is the second option.

(1/8 + 3/12) x (1 1/6-1/2)
aivan3 [116]

Answer:

1/2

Step-by-step explanation:

(1/8+3/12)×(11/6-1/2)

Using bodmas

Deal with the bracket first and it should start with the addition

1/8+3/12

Lcm of the two is 96

12+24/96

=36/96

Then move to the next bracket

11/6-1/2

Lcm is 6

11-3/6

=8/6

Bring the two answers together

36/96×8/6

=1/2

The quadratic formula gives which roots for the equation 2x^2 + x - 6 = 0?
Jet001 [13]

Answer:

The roots are x = (\frac{3}{2}, -2), which is given by option C.

Step-by-step explanation:

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

ax^{2} + bx + c, a\neq0.

This polynomial has roots x_{1}, x_{2} such that ax^{2} + bx + c = a(x - x_{1})*(x - x_{2}), given by the following formulas:

x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}

x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}

\Delta = b^{2} - 4ac

In this question, we have that:

2x^2 + x - 6 = 0

Which is a quadratic equation with a = 2, b = 1, c = -6. So

\Delta = 1^{2} - 4*2(-6) = 1 + 48 = 49

x_{1} = \frac{-1 + \sqrt{49}}{2*2} = \frac{6}{4} = \frac{3}{2}

x_{2} = \frac{-1 - \sqrt{49}}{2*2} = \frac{-8}{4} = -2

So the roots are x = (\frac{3}{2}, -2), which is given by option C.

Ajutați mă vă rog la asta La o sărbătoare , fiecare copil dintr-o grădiniță a primit o carte de 32 lei și o ciocolată de 8 lei.C
Svetradugi [14.3K]

Answer:

50 de copii

Step-by-step explanation:

În această întrebare, fiecare dintre copii primește o carte pentru 32 de lei și o ciocolată pentru 8 lei.

Ceea ce înseamnă că suma totală primită de fiecare dintre copii va fi de 32 + 8 = 40 lei

Acum, din moment ce suma totală cheltuită este de 2000 de lei, numărul copiilor care se dau cărți și ciocolată va fi de

2000/40 = 50 de copii

A pie were cut in 8 equal slices and 3/4 were eaten how many slices were ate
Murljashka [212]
2 slices are left left because if you change the 8 to a fraction it will turn to this 8/8 and you need to change 3/4 to have the same denominator as the 8/8 so 3/4 will turn to 6/8 and then you subtract 8/8 by 6/8 and itll be 2/8 left so the answwer is 2 slices left
