Answer:
Check boxes 3, 4, 6, and 8.
Step-by-step explanation:
We have the equation:

And we want to select all equations that are perpendicular to the above equation.
Remember that perpendicular lines have slopes who are negative reciprocals of each other.
Therefore, the slope of our equations must be the negative reciprocal of -3.
The negative reciprocal of -3 is 1/3. We flipped -3 to -1/3, and then multiplied by a negative.
Therefore, any equation with a slope of 1/3 is perpendicular to our original line.
Therefore, we will check boxes 3, 4, 6, and 8.
Answer:
480 inches cubed
Step-by-step explanation:
Volume= l*w*h
Volume= 12*8*2.5
Volume= 240 inches cubed
The problem asks for the volume of TWO boxes so multiply the volume by 2 and you get a volume of 480 inches cubed
The x-intercept is 8 because it passes through the horizontal line (x) at point 8.
The y-intercept is -4 because it passes through the vertical line a (y) at point -4.
The correct answer is B.
Hope this helps!
