48 = -18x is an equivalent expression because you just subtact -18 from both sides.
Answer: Choice C
(4, 18)
=========================================
Explanation:
One point shown on the graph is (2,9)
If we double each x and y coordinate, then
We go from (2,9) to (4,18)
Plotting this point on the graph will be on the same line as the other points.
Or you could note that y/x = 9/2 = 18/4 = 4.5
Answer:
7.2 m²
Step-by-step explanation:
Use the appropriate area formula, fill in the given values, and do the arithmetic.
A = (1/2)ab·sin(C)
where "a" and "b" represent triangle side lengths and C is the angle between them.
A = (1/2)(4 m)(8.5 m)sin(25°) ≈ 7.2 m²
Answer: 4. 432 cm^2/2 = 216 cm^2
6. 309.76 mm^2
8. pi * 22^2 = 484pi (or, approximately 1,519.76) in^2
484/2 = 242pi or 759.88 in^2.
10. 297.84 in^2/2 = 148.92 in^2
Step-by-step explanation:
To find the area of a triangle, you take the base and multiply by the height, and then divide by 2. Hence giving me the answers I obtained in #4 and #10.
A square is equal on all sides, so you would just square the measurement of the one side.
To find the area of a circle, you would do pi times the radius^2. Since this is a semicircle, you actually should divide the number you got by 2. (Which is why I did so up above).
