the aspect ratio of a rectangular shape is it's length divided by it's width (l/w). if the aspect ratio of a chalkboard is 4: 3 and the width is 5 in, what is the length of the chalkboard?
a. 6.67 in
b. 9.33 in
c. 12 in
d. 14 in

  A. 6.67 in

Step-by-step explanation:

Given : The aspect ratio of a rectangular shape is it's length divided by it's width (L/W).

Let 'l' be the length of the rectangular shaped chalkboard.

If  the aspect ratio of a chalkboard is 4:3 and the width is 5 in then we have

Multiply 5 on each side , we get

Hence, the length of the chalkboard = 6.67 in.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
