A number is increased by 40 % and becomes 364. What
was the original number?

218.4

Step-by-step explanation:

Change the percentage to a decimal by dividing it by 100

40/100=0.4

Multiply the original value by the decimal to determine the percentage value.

364 * 0.4 = 145.6

Subtract the percentage value from the original price

364 - 145.6= 218.4

Check your work:

218.4 + 145.6 = 364

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
