Step-by-step explanation:
The initial image of the photo is 2 in by 4 in. The mat is 4 in by 6 in.
The new image is dilated by a scale of 2. So we double the dimensions. The new photo is 4 in by 8 in. The new mat is 8 in by 12 in.
Answer:
the slope is -1
Step-by-step explanation:
To find the slope, we use the formula
m = (y2-y1)/ (x2-x1)
= (4--1)/ (-1-4)
= (4+1)/(-5)
= 5/-5
= -1
If its a reflection across the y axis the x value is reflected and the y value stays the same, so (-3,7)
Recognize that you must combine "like" terms. 5x^2y and x^2y are "like" terms.
Adding them together, you get 6x^2y.
Now add 2xy^2 to 6x^2y. These are NOT "like" terms, so you end up with
6x^2y+2xy^2 as your final answer. This answer is acceptable as is.
However, you could factor out the common factors: 2xy(3x+y).
