find the value of a cube + b cube when a+b = 5 and ab = 3

Answers

Answer 1

As we know :

[tex] \boxed{ \boxed{ {(a + b)}^{3} = {a}^{3} + {b}^{3} + 3ab(a + b) }}[/tex]

now let's plug the value of given terms :

(5)³ = a³ + b³ + (3×3)(5)

125 = a³ + b³ + 45

a³ + b³ = 125 - 45

a³ + b³ = 80

Answers

Step-by-step explanation:

Given-

5.1 km/hr

Relation bween mph and km :-

[tex]1 \: mph = 1.609 \: km[/tex]

So,

[tex] \frac{5.1 \: km}{1 \: h} \times \frac{1 \: km}{1.609} = 3.17 \: mph[/tex]

Therefore, the answer is 3.17 mph.

Write an equation of the line that passes through the point (3,3) and is parallel to the line y= -1/2 + 3

Answers

Step-by-step explanation:

the slope = -½

the equation :

y-3 = -½(x-3)

y-3 = -½x + 3/2

y = -½x + 3/2 +3

y = -½x + 9/2

Which statement explains why 13x−13y=−26 shares a solution with this system of equations:

10x−3y=29

−3x+10y=55

Answers

The given equation is derivable from the system of equations.

Response:

The reason why 13·x - 13·y shares a solution with the given system of equation is because -13·x - 13·y equals 55. I can subtract -3·x + 10 from the left side of 10·x - 3·y = 29, and subtract 55 from its right side. Subtracting equivalent expressions from each side of an equation does not change the solution of the equation.

Method by which the relationship between the equations was determined

Given:

The system of equation is presented as follows;

[tex]\begin{cases} \mathbf{10 \cdot x - 3 \cdot y} = 29...(1) & \text{ } \\ \mathbf{-3 \cdot x + 10 \cdot y} = 55...(2) & \text{ } \end{cases}\\[/tex]

Therefore, by subtracting equation (2) from equation (1), we have;

(10·x - 3·y) - (-3·x + 10·y) = 29 - 55 by subtracting equivalent expressions

13·x - 13·y = 29 - 55 = -26

13·x - 13·y = -26, which is the given equation

Given that the operation performed on equation (1) and (2) is the

subtraction of equivalent expressions, we have, that the solution for the

given equation, 13·x - 13·y = -26 is the same as the solution for given

system of equations.

The reason why 13·x - 13·y = -26 shares a solution with the system of equations based from the given options in a similar question is therefore;

D. because -3·x + 10·y is equal to 55, I can subtract -3·x + 10·y from the left side of 10·x - 3·y = 29 and subtract 55 from its right side. Subtracting equivalent expressions from each side of an equation does not change the solution to the equation

Step-by-step explanation:

Factoring is always an efficient method of solving a quadratic, if it has nice integer factors that can be easily identified. Here, the two prime factors of 35 have a sum of 12, so the factored form is easily found to be ...

  (x +5)(x +7) = 0

This basically shows you the solutions are x=-5 and x=-7 "by inspection" in one step.

By contrast, the quadratic formula has 4 multiplications, a division, a square root, and 3 additions. That's a significant amount of arithmetic to get to the answers.
