(3 x 10^6)(8 x 10^-4) = (3 x 8) x 10^(6 - 4) = 24 x 10^2 = 2.4 x 10^3
Answer:
2.5 rounds to 3
Step-by-step explanation:
5 divided by (or 5/2) 2 is 2.5 and since its not a whole number you rounded by the ones and you get 3.
Basiclaly solve for y
8x+4y=16
minus 8x both sides
4y=-8x+16
divide by 4 both sides
y=-2x+4
Answer:
(-1/2, 27/2)
Step-by-step explanation:
Midpoint formula: (x^1 +x^2/ 2, y^1 +y^2/ 2)
(-4 +3 /2, 12+15/ 2) -> (-1/2, 27/2)
The coordinates of the image of point B after the triangle is rotated 270° about the origin is (4, 2)
<h3>How to determine the image of point B?</h3>
The complete question is added as an attachment
From the attached image, we have the following coordinate
B = (-2, 4)
When the triangle is rotated by 270 degrees, the rule of rotation is:
(x, y) ⇒ (y, -x)
For point B, we have:
B' = (4, 2)
Hence, the coordinates of the image of point B after the triangle is rotated 270° about the origin is (4, 2)
