The scale drawing of the computer lab will have a length of 4 centimeter and a widtgh of 6 centimeter.
Answer is -pi
Let x be this unknown number. Adding on x to pi gets us the expression x+pi
If we set x+pi equal to zero (which is a rational number) and solve for x, we get
x+pi = 0
x+pi - pi = 0 - pi
x = -pi
so adding pi to -pi will lead to 0 since
x+pi = -pi+pi = 0
Answer:
A. 4.4 units²
Step-by-step explanation:
Area of a Triangle: A = 1/2bh
sin∅ = opposite/hypotenuse
cos∅ = adjacent/hypotenuse
Step 1: Draw the altitude down the center of the triangle
- We should get a perpendicular bisector that creates 90° ∠ and JM = KM
- We should also see that we use sin∅ to find the <em>h</em> height of the triangle and that we use cos∅ to find length of JM to find <em>b</em> base of the triangle
Step 2: Find <em>h</em>
sin70° = h/3.7
3.7sin70° = h
h = 3.47686
Step 3: Find <em>b</em>
cos70° = JM/3.7
3.7cos70° = JM
JM = 1.26547
Step 4: Find entire length base JK
JM + KM = JK
JM = KM (Definition of Perpendicular bisector)
2(JM) = JK
2(1.26547) = 2.53095
b = 2.53095
Step 5: Find area
A = 1/2(3.47686)(2.53095)
A = 4.39988
A ≈ 4.4
Answer:
7x - 9
Step-by-step explanation:
1: Multiply the numbers
4 - 3 x 2 + 2x + 5x - 7
4 - 6 + 2x + 5x - 7
2: Add the numbers
4 - 6 + 2x + 5x - 7
-9 + 2x + 5x
3: Combine like terms
-9 + 2x + 5x
-9 + 7x
4: Rearange terms
-9 + 7x
7x - 9
Solution
7x - 9

You swap x and y. for example, the first set is (0,1) so the inverse would be (1,0)
