Answer: It is 2.
Step-by-step explanation:
Make both equation equal to each other and solve for x, as following:
- Add like terms.
- Factor the equation.
Substitute the value of x obtained into any of the original equations to obtain the y-coordinate.
Then, this is:
It is a good idea to check to see if your answer is reasonable because a. if your answer is reasonable, you have probably done the problem correctly.
<span>Declaring the volume function
double PyramidVolume(double baseLength, double baseWidth, double pyramidHeight){
double baseArea = baseLength * baseWidth;
double vol = ((baseArea * pyramidHeight) * 1/3);
return vol;
}
int main() {
cout << "Volume for 1.0, 1.0, 1.0 is: " << PyramidVolume(1.0, 1.0, 1.0) << endl;
return 0;
}
Defining the function,
include <iostream>
double PyramidVolume(double, double, double);
int main()
{
std::cout << "Volume for 1.0, 1.0, 1.0 is: " << PyramidVolume(1.0, 1.0, 1.0) << std::endl;
return 0;
}
double PyramidVolume(double length, double width, double height)
{
return length * width * height / 3;
}</span>
Insert (1,1) -> x=1, y=1 into the equation and check if both side are equal:
y=3x-2
1=3*1-2
1=1
so yes the ordered pair is a solution of the equation
