Answer:

The system of equations 3x + 7y = 80 and 6x + 3y = 63.75 can be used to determine the cost of one CD and one DVD.

Step-by-step explanation:

Given that:

Cost of 3 CDs and 7 DVDs = $80

Cost of 6 CDs and 3 DVDs = $63.75

Let,

x be the cost of one CD

y be the cost of one DVD

According to given statement;

3x + 7y = 80

6x + 3y = 63.75

Hence,

The system of equations 3x + 7y = 80 and 6x + 3y = 63.75 can be used to determine the cost of one CD and one DVD.

Answer:

x=4

Step-by-step explanation:

--8(x + 4) +40= 12- 9x

(distribute -8 to x and 4)

-8x+8=12-9x

(add 9x to both sides)

-8x+8+9x=12

(combine -8x and 9x to get x)

x+8=12

(subtract 8 from both sides)

X=4

The time required for the two stocks of Jones Corporation and Overton Company to be nearly equal in value, is 30 months.

A stock is the portion of ownership of a firm, corporation etc which gives the security of asset of the property.

Stock for the Jones Corporation starts with a value of $39.63 and gains $0.30 in value per month.

Stock for the Overton Company starts with a value of $24.45 and gains $0.80 in value per month.

Let after the x month's these two stocks nearly equal in value.

[tex]39.63+0.30\times x=24.45 +0.80 \times x[/tex]

Solve it further,

[tex]0.80 \times x-0.30\times x=39.63-24.45 \\0.50 \times x=15.18\\x=\dfrac{15.81}{0.50}\\x=30.36[/tex]

Hence, the time required for the two stocks of Jones Corporation and Overton Company to be nearly equal in value, is 30 months.

Answer:

  y = 2(x +2)(x -4)

Step-by-step explanation:

The y-intercept will be a constant times the product of the roots. Here, the product of the roots is (-2)(4) = -8, so the constant of interest is -16/-8 = 2. That constant is the coefficient of the leading term of the quadratic, so is a multiplier of the factored form.

  y = 2(x +2)(x -4)

__

For root p, (x-p) is a factor in the factored form.

Answer: To find the number of [tex]\dfrac18[/tex] cups required, we will divide To find the number of [tex]\dfrac18[/tex] cups required, we will divide required quantity by [tex]\dfrac18.[/tex] by [tex]\dfrac18.[/tex]

Step-by-step explanation:

Patrick needs [tex]\dfrac34[/tex] cups of orange juice.

Capacity of measuring of cup = [tex]\dfrac18[/tex] cup

To find the number of [tex]\dfrac18[/tex] cups required, we will divide required quantity by [tex]\dfrac18.[/tex]

Required number of [tex]\dfrac18[/tex] cups  = [tex]\dfrac34\div\dfrac18=\dfrac34\times8=3\times2=6[/tex]

Hence, six [tex]\dfrac18[/tex] cups are required for [tex]\dfrac34[/tex] cups of orange juice..

The number of 1/8 cups Patrick can use to measure 3/4 cup is 6 cups.

A fraction is a number that is made up of a numerator and a denominator. An example of a fraction is 1/8. 1 is the numerator. 8 is the denominator.

Determination of the number of 1/8 cups needed

In order to determine the number of 1/8 cups needed, divide 3/4 by 1/8

3/4 ÷ 1/8

3/4 x 8

= 6 cups
