Solve each system of equations by writing a new system that eliminates one of the variables.
1 answer:
Answer:
Step-by-step explanation:
Let:
We need to eliminate one of the variables, so let's use elimination method. First multiply (1) by 4 and (2) by 3:
Now subtract 3*(2) from 4*(1) in order to eliminate x:
Solving for y:
Multiplying both sides by -1/13
Finally, replacing the value of y in (1)
Solving for x:
add 2 to both sides:
Multiply both sides by 1/3:

To check if a piecewise defined function is continuous, you need to check how the pieces "glue" together when you step from one domain to the other.
So, the question is: what happens at x=3? If you reach x=3 from values slightly smaller than 3, you obey the rule f(x)=log(3x). So, as you approach 3, you get values closer and closer to
Similarly, if you reach x=3 from values slightly greater than 3, you obey the rule f(x)=(4-x)log(9). So, as you approach 3, you get values closer and closer to
So, the function is continuous at x=3, because both pieces approach log(9) as x approaches 3.
The height of squared pyramid is unit.
A cube is a solid three-dimensional object with six square faces or sides, three of which meet at each vertex. One of the five Platonic solids, the cube is the only regular hexahedron. It contains 8 vertices, 6 faces, and 12 edges.
Volume of cube
Given the height of cube is unit.
Volume of cube is
Let the height of squared pyramid is unit
Volume of squared pyramid is
According to the question, we have
Volume of cube = volume of squared pyramid
Therefore, the height of squared pyramid is unit.
