The function that takes three decimal numbers as inputs and finds the sum of those inputs and returns the sum has been given below
What is programming?
Program is the set of instructions given to the computer so that the computer can execute those instructions. The act of writing program is called programming.
The program has been shown below
#include<stdio.h>
using namespace std;
int main()
{
double n1, n2, n3;
double s;
printf("Enter first numbers");
scanf(%lf, &n1);
printf("Enter second numbers");
scanf(%lf, &n2);
printf("Enter third numbers");
scanf(%lf, &n3);
s = n1 + n2 + n3;
printf("Sum = %f", s);
return 0;
}

Answer:
The second one
Step-by-step explanation:
A linear function will always increase or decrease by the same amount:
The first one adds eight for every increase of 1 in the x value
The third one subtracts three for every increase of 1 in the x value
However,
The second one starts by adding three, and then adds 1.5 for the rest
The second table is nonlinear
Slope intercept form is
, where 'm' is the slope and 'b' is the y-intercept.
Subtract 6x to both sides:
Divide 5 to both sides:
Answer:
Step-by-step explanation:
Given the simultaneous equation
3x+4y=15. Equation 1
3x-y=30. Equation 2
Using elimination method
Sutract equation 2 from 1
Then, will have
3x-3x+4y--y=15-50. -×-=+
4y+y=-15
5y=-15
Divide Both sides by 5
y=-15/5
y=-3
From equation 2
3x-y=30
3x--3=30
3x+3=30
3x=30-3
3x=27
Divide both side by 3
x=27/3
x=9
Then, x=9 and y=-3
