Given three consecutive odd integers, what is the greatest number if triple of the sum of thrice the third one and twice the first one is equal to 291? ( grid-in )

Answers

Let n be the smallest of these integers. The other two are then n + 2 and n + 4.

"triple of the sum of thrice the third one and twice the first one is equal to 291" is a long-winded way of saying

3 (3 (n + 4) + 2n) = 291

Solve for n :

3 (3n + 12 + 2n) + 291

3 (5n + 12) = 291

15n + 36 = 291

15n = 255

n = 17

Then the greatest of the three integers is n + 4 = 21.

How many solutions does the equation 3x 6 = − 1 − 3 4x have? two zero one infinitely many

Answers

The nature of solutions to equations can be finite, infinite or no solution. The solution to the system of equation 3x + 6 = -1-3 + 4x is 10

Solution to system of equations

The nature of solutions to equations can be finite, infinite or no solution.

Given the linear solution as shown:

3x + 6 = -1-3 + 4x

Collect the like terms

3x - 4x = -1 -3 -6

-x = -10

Multiply both sides by -1

-(-x) = -(-10)
x = 10

Hence the solution to the system of equation 3x + 6 = -1-3 + 4x is 10

If Sandra charges $4.00 for a cup of ice cream and $0.37 for each ice cream, What
function would represent the situation?
Remember it should look like y=mx+b.

Answers

Answer:y= 0.37x+4

Step-by-step explanation:
x is the amouny of ice cream, 0.37 is the amount charged per x plus the additional 4 for the cup

The slope of the linear equation is 0.37, then the linear equation will be represented as y = 0.37x + 4.

What is the linear system?

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

If Sandra charges $4.00 for a cup of ice cream and $0.37 for each ice cream. Then the linear equation is given as

[tex]\rm y=mx+c[/tex]

We have

m = $0.37

c = $4

Then the linear equation will be

y = 0.37x + 4

The equation of the hyperbola is D. [tex]y^2/16^2-x^2/12^2=1[/tex]

Calculations and Parameters:

Given that the focus is at (0, 20)

Directrix is y= -256/20

What is the relation between a, b, and c?

Answer:

120 cars

Step-by-step explanation:

The given function is

[tex]C(x)=0.5x^2-120x+21,481[/tex]

and its parent function would be

[tex]f(x)=ax^2+bx+c[/tex]

So,

[tex]a=0.5[/tex]

[tex]b = -120[/tex]

and

[tex]c = 21,481[/tex]

The minimum cost would be found using:

[tex]x = -\frac{b}{2a}[/tex]

So just input a and b into the function:

[tex]x= -\frac{-120}{2(0.5)}[/tex]

[tex]x=-\frac{-120}{1}[/tex]

[tex]x = 120[/tex]

Therefore there must be 120 cars made to minimize the cost.
