Answer:
1. True
2. False
3. True
Step-by-step explanation:
1. (x,y) = (3,1). x = 3; y = 1
2. Vertical is y and horizontal is x
3. The origin is (0,0), The only time these two x and y axis intercept.
Answer:
4 airplanes
Step-by-step explanation:
1 = 2/3
6 = x
cross multiply
x = 6 × 2/3
therefore x = 4

Answer:
The perpendicular line would be y = -3x - 7
Step-by-step explanation:
To find the equation of the line, we first need to solve the original line for y.
-x + 3y = 9
3y = x + 9
y = 1/3x + 3
Now we know the slope of the original line to be 1/3. Since perpendicular lines have opposite and reciprocal slope, we know the new line to have a slope of -3. We can then use that along with the given point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 2 = -3(x + 3)
y - 2 = -3x - 9
y = -3x - 7
Kelly and Adam are buying candy boxes to give to friends
Step-by-step explanation:
Kelly statement is true.
1. Kelly buy a candy box which is cone -shaped with radius x.
2.Adam buy a candy box which is square pyramid shape with same height as Kelly's box but the side length is xπ√.
3.Two candy boxes have different in shape so volumes of the boxes will be different.
