Answer:
y = -3x + 8
Step-by-step explanation:
The slope of a perpendicular line to the original equation is the opposite reciprocal of the slope of the original equation. This makes the opposite reciprocal -3, so the slope of the perpendicular line is -3.
Now that we have found the slope, we will put it into the formula for slope, y = mx + b. This results in getting y = -3x + b.
We know the values for x and y, (1,5) respectively. Plug these values into y = -3x + b.
5 = -3(1) + b
b = 8
This means that 8 is your y intercept and goes into place for b
Therefore, your resulting equation is y = -3x + 8

what says what is wrong?
The given pyramid's total surface area is 3. 24.0 square feet.
Step-by-step explanation:
Step 1:
To calculate the surface area of the given figure, we need to find the surface areas of the different shapes in the figure.
There are 3 triangles and 1 square in the figure.
Step 2:
All the triangles are similar.
The surface area of a triangle =
The similar triangles have a base length of 3 feet and a height of 2.5 feet.
The surface area of 1 similar triangle = square feet.
The surface area for all the similar triangles = square feet.
Step 3:
The surface area of a square is the square of its side length. The square has a side length of 3 feet.
The surface area of the square = square feet.
Step 4:
To calculate the total surface area we sum up all the individual surface area.
The total surface area = square feet which is the third option.
