Answer:
14 gel pens/minute
Step-by-step explanation:
divide the amount by time.
210/15 = 14
To determine which line the point lies on, you can just plug in one of the numbers into the equations to see if it equals out.
(2, -1) I will use the 2 and plug it in for x in the equation.
y = 2x + 1
y = 2(2) + 1
y = 5 The point does not lie on this line because when x = 2, y = 5 (2, 5)
y = x + 5
y = 2 + 5
y = 7 The point does not lie on this line because when x = 2, y = 7 (2, 7)
y = 2x - 5
y = 2(2) - 5
y = 4 - 5
y = -1 The point does lie on this line because when x = 2, y = -1 (2, -1)
y = x - 2
y = 2 - 2
y = 0 The point does not lie on this line because when x = 2, y = 0 (2, 0)
Answer:
B
Step-by-step explanation:
Transformation that maps triangle XYZ into triangle X'Y'Z' is a translation 3 units to the right and 1 unit down, because
- X(0,0)→X'(3,-1);
- Y(2,3)→Y'(5,2);
- Z(4,-1)→Z'(7,-2).
So, the algebraic ru;e of the transformation is
(x,y)→(x+3,y-1)
Answer:
22
Step-by-step explanation:
but be more especific
11 units
sin45°=√2 / 2
the length of one leg = √2/2 . 22/√2 = 11
