This system of linear equation has infinite solutions because they are really the same equation.

12x + 3y = 21
3y = -12x + 21  Divide through by 3:-

y = -4x + 7  <-------- which is the first equation

liubo4ka [24]

Answer:

12 inches

Step-by-step explanation:

Ahmed received a box of gifts. The box is a rectangular prism with the same height and width, and the length

is twice the width. The volume of the box is 3,456 in? What is the height of the box?

Volume of a Rectangular pyramid = Length × Width × Height

From the above question

Height = Width = x

Length = 2 × Width

Length = 2x

Volume = 3,456 cubic inches

Hence,

3,456 = 2x × x × x

3456 = 2x³

x³ = 3456/2

x³ = 1728

Cube root both sides

Cube root(x³) = cube root (1728 cubic Inches)

x = 12 inches

Therefore, the height is 12 inches

The final cost of a sale item is determined by multiplying the price on the tag by 75%. Which best describes the function that r
scoundrel [369]

First we try to frame the equation between the sale price and the final cost.

Let us consider, the price to be x and the final cost to be y, since the final cost is 75% of the price, we have the below equation

y = 0.75x

This is of the form of straight line equation y = mx +c where c =0 and m = 0.75

This means the function is linear since it satisfies a straight line equation.

So, we can eliminate options (3) and (4)

Now, the function is not a continuous one because the function is has definite value which is 0.75x and this make the function discrete. Hence option (2) is eliminated

Therefore we are left with option (1) which is the answer

Answer is (1) It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant
