Evaluate 3 7 r + 5 8 s 7 3 r+ 8 5 sstart fraction, 3, divided by, 7, end fraction, r, plus, start fraction, 5, divided by, 8, end fraction, s when r = 14 r=14r, equals, 14 and s = 8 s=8s, equals, 8.

Therefore the value of given expression when r = 14 and s = 8 is

Step-by-step explanation:

Given:

To Find:

Value of above  equation when r = 14 and s = 8

Solution:

.............Given

Put,

Now 7 × 2 = 14 and 8 will cancel each other we get

Therefore the value of given expression is

answer: 298143

step-by-step explanation:

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.
