True or false: When a figure on a coordinate grid is translated down and to the right, the vertex with the largest y-coordinate

Montano1993 [528]

Answer:

True

Step-by-step explanation:

Translation down and to the right doesn't change the dimensions of the original figure.

This will change coordinates of each vertex but the highest coordinates of the pre-image and image will correspond to each other.

Phân tích : x^3+2x^2y+xy^2-9x

Galina-37 [17]

Answer:

x(x+y+3)(x+y-3)

Step-by-step explanation:

x³+2x²y+xy²-9x

= x((x²+2xy+y²)-3²)

= x((x+y)² - 3²)

= x(x+y+3)(x+y-3)

Point Q is the midpoint of GH. GQ=2x+3, and GH=5x−5 .

olasank [31]

Since point Q is the midpoint of GH, that means that GH-GQ=HQ=GQ (since Q is the midpoint). Plugging them in, we get 5x-5-(2x+3)=3x-8=GQ=HQ. Since Q is the midpoint, that means that 3x-8=2x+3=GQ=HQ. Subtracting 2x from both sides as well as adding 8, we get that x=11 and 2(11)+3=25=GQ by plugging x into 2x+3
