Answer:
Step-by-step explanation:
We are given;
- A point where the line is passing through as (3, -4)
- The slope of the line -1/2
We are required to determine the equation of the line;
- Note that, one way we can get the equation of a straight line is when we are given a point where the line is passing through and its slope.
- Thus, in this case, we can determine the equation;
Taking another point (x, y)
Then; (x, y) , ( 3, -4) and slope -1/2 can give us the equation;
That is;
Cross multiplication;
Combining the like terms;
Thus, the equation of the line is;
Answer:
504 cm squared
Step-by-step explanation:
To find the surface area, find the area of the square base and add it to the area of each triangle face.
Find the area of the base by multiplying base length by base length.
Here the base is 12 x 12 = 144.
Find the area of each triangle face by multiplying 1/2 * b*h.
Here the area is 1/2 * 12 * 15 = 90. Since there are 4 faces, the total area is 4 * 90 = 360.
Together the surface area is 360 + 144 = 504.
