Answer:
[tex] \frac{ - 8}{11} = \frac{12}{x} \\ cross \: multipliation \\ 12 \times 11 = - 8 \times x \\ x = \frac{12 \times 11}{ - 8} = \frac{3 \times 11}{ - 2} = \frac{33}{ - 2} = - 16.5[/tex]
One month Dante rented 2 movies and 3 video games for a total of$22 . The next month he rented 4 movies and 8 video games for a total of$57 . Find the rental cost for each movie and each video game.
Answer:
x = $1.25; y = $6.50
Step-by-step explanation:
Let x be the cost of movies and y be cost of video games.
Month 1 has 2x+3y = 22
So here x = (22-3y)/2 and y = (22-2x)/3
Month 2 has 4x+8y =57
Here x = (57-8y)/4 and y = (57-4x)/8
Now you have two options: Find the y or the x. I will demo the x and you can try the y if you wish.
(22-2x)/3 = (57-4x)/8
176-16x = 171-12x
-4x = -5
x = 1.25
Now with the x found, you plug it into either of the y equations to figure out the other variable.
y = (22-2(1.25))/3
y = 6.5
And to double check:
y = (57-4(1.25))/8
y = 6.5

Answer:
The quadratic x2 − 5x + 6 factors as (x − 2)(x − 3). Hence the equation x2 − 5x + 6 = 0
has solutions x = 2 and x = 3.
Similarly we can factor the cubic x3 − 6x2 + 11x − 6 as (x − 1)(x − 2)(x − 3), which enables us to show that the solutions of x3 − 6x2 + 11x − 6 = 0 are x = 1, x = 2 or x = 3. In this module we will see how to arrive at this factorisation.
Polynomials in many respects behave like whole numbers or the integers. We can add, subtract and multiply two or more polynomials together to obtain another polynomial. Just as we can divide one whole number by another, producing a quotient and remainder, we can divide one polynomial by another and obtain a quotient and remainder, which are also polynomials.
A quadratic equation of the form ax2 + bx + c has either 0, 1 or 2 solutions, depending on whether the discriminant is negative, zero or positive. The number of solutions of the this equation assisted us in drawing the graph of the quadratic function y = ax2 + bx + c. Similarly, information about the roots of a polynomial equation enables us to give a rough sketch of the corresponding polynomial function.
As well as being intrinsically interesting objects, polynomials have important applications in the real world. One such application to error-correcting codes is discussed in the Appendix to this module.

Step-by-step explanation:
A quotient is a fraction.
A sum is addition.
A variable is an unknown number shown by using a letter.
Therefore, the answers for quotient and variable in this picture should be switched. However, the negative sign has to be included, so the quotient should be a -9/y.

Kinetic energy can be calculated using the formula KE=1/2mv²,
where m= mass and v= velocity.
Calculate the kinetic energy of an object with mass 5kg moving at a velocity of 4m/s.
Answer:
40J
Step-by-step explanation:
YOU say 1/2 x 5 x4² ( 4 is velocity. 5 is mass )
it becomes 1/2 x5 x16
then it becomes 1/2 x 80
half of 80 is 40
the answer is then 40 JUOLES

The numbers are measurements of radius diameter and circumference of circles A and B. Circle A is smaller than Circle B which number belongs to which quantity? 2.5, 5, 7.6, 15.2, 15.7, 47.7
Step-by-step explanation:
a diameter is always twice the radius.
the only pairs in this list, where one number is twice the other, is :
2.5 and 5
7.6 and 15.2
so,
2.5 is the radius of A
5 is the diameter of A
7.6 is the radius of B
15.2 is the diameter of B
15.7 is then the circumference of A (as the smaller of the remaining 2 numbers).
47.7 is the circumference of B.
this is also proven by the formula for the circumference of a circle : c = 2×pi×r

Thanks~
Answer:
x=–(3/4)
Step-by-step explanation:
Subtract 5x from both sides:
−3x−5x=5x+6−5x
Simplify:
−8x=6
Divide both sides by −8
−8x/−8 =6/−8
Simplify again, result will be:
x=−(3/4)
