1) Parellel because if she had sliced perpendicular, she would have gotten a square and a triangle.
2) Perpendicular because if she had sliced parallel, she would have gotten a (once more) square and a triangle.
1) First shape and Last shape (the cylinder and the cone).
2) First shape and Second shape (the pyramid and the cone).
Answer:
3 x -3y = -9y
3 x -1 = -3
The factored expression is 3(-3y - 1)
Step-by-step explanation:
All you have to do is -9y / 3 = -3y and -3 / 3 = -1, then put those numbers in parentheses. All of that is multiplied by 3.
The reason is because if you distributed the 3 it would become:
3 * -3y + 3 * -1 = -9y - 3
Answer:
50 degrees
Step-by-step explanation:
x + y = 90
x = 2y - 30
2y - 30 + y = 90
3y - 30 = 90
3y = 90 + 30
3y = 120
y = 120/3
y = 40
x = 2y - 30
x = 2(40) - 30
x = 80 - 30
x = 50 <====== angle x
Answer:
y = 4
Step-by-step explanation:
Since the line if parallel to the x-axis, regardless of the value of x, y will be equal to 4. In general, then, the points on the line are (x,4), where x is any value, including 1.
Answer:
B
