Answer:
The dimensions are <u>15 x 6</u>
Step-by-step explanation:
Length (L) Width (W)
Perimeter = (W x 2) + (L x 2)
L = (W x 2) + 3
L x 2 = (W x 4) + 6
42 - 6 = 36
36 ÷ 6 = 6
6 x 2 + 3 = 15
<u>Perimeter = (6 x 2) + (15 x 2) = 42</u>
Answer:
- 2. Rotate the triangle 90º clockwise about the origin and then translate it 10 units left and 9 units down.
Step-by-step explanation:
- <em>Easy way to take one of the vertices and apply the transformations</em>
1. Rotate the triangle 90º counterclockwise about the origin and then translate it 10 units left and 9 units down.
2. Rotate the triangle 90º clockwise about the origin and then translate it 10 units left and 9 units down.
- True
- (-3, 3) → (3, 3) → (3 - 10, 3 - 9) = (-7, -6)
3. Rotate the triangle 90º counterclockwise about the origin then translate it 1 unit up.
4. Rotate the triangle 90º clockwise about the origin then translate it 1 unit up.
Answer:
X + 50 =180 ( being straight angle)
or, X =180 - 50
X = 130
If Angle M is y then,
Step-by-step explanation:
(6y) + (3y -6) + y = 180°
10y - 6 = 180
10y = 186
y= 18.6
Angle O = 3(18.6) - 6 = 49.8
Answer <u><em>4</em><em>9</em><em>.</em><em>8</em></u>

Answer:
21
Step-by-step explanation:
It is given that y varies inversely with x.
...(i)
where, k is constant of proportionality.
It is given that x=-3 when y=-105. Substitute these values in equation (i), to find the value of k.
Now,
Substitute x=15 in the above equation.
Therefore, the value of y is 21 when x=15.
