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

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
