the height of a window is 0.6 feet less than 2.5 times its width. if the height of the window is 4.9 feet, which equation can be used to determine x, the width of the window?

a. 2.5x + 0.6 = 4.9

b. 2.5x - 0.6 = 4.9

c. 0.6x + 2.5 = 4.9

d. 0.6x - 2.5 = 4.9

Option B is correct

Step-by-step explanation:

Here, x represents the width of the window.

Given the statement:

The height of a window is 0.6 feet less than 2.5 times its width

⇒         ....[1]

It is also given that:

If the height of the window is 4.9 feet.

ft

Substitute in [1] we have;

Therefore,  an equation can be used to determine x, the width of the window is,

d. 9

step-by-step explanation:

in the table given in the picture, x is the input of the function and f(x) is the output on the given input. in the given table, it can be read as the value of function at -3 is it's respective value of f(x) which is -9.

as we have to find the value of f(3), we will see that what is the value of output on input 3. we can see in the table that the output value at x=3 is 9.

so, option d is the correct answer ..

x
