Answer:
115
Step-by-step explanation:
set up the equation to find x:
GFN+NFG=GFE
(4x+10)+(14x+3)=157
calculate for x
you'll get x=8
put 8 into NFE
14(8)+3=115
<span>The ordered pair is (5000,12). This is given from the function a at x=5000, which is written in the question as a(5000)=12. Here, a is our dependent variable and is equal to 12. The x value, or independent variable is given as 5000. Ordered pairs are written (x,y) or (independent, dependent), thus the ordered pair is (5000,12).</span>
Numbers: 1,2,4,5,7,8
There are 4 digits __ __ __ __
1st digit can be filled by any of the 6 numbers
Similarly 2nd, 3rd and 4th
Hence each digit will have 6 possibilities
<span>Therefore no.of 4 digit numbers that can be formed are 6 x 6 x 6 x 6 = </span><span>1296</span>
Answer:
We are given that:
Now we are asked to show that:
We know that:
Hence using equation (1) we get:
Also we know that:
and
so using above two formula in equation (2) we get:
( since we know that:
)
Hence we have proved that:
