Answer:
Step-by-step explanation:
Point Slope is:
We are given the point (-2, 5) and a slope of 1/2.
Hope this helps.
The area scales with the square of the scale factor: the dilation has a certain scale 
, the area scales with a factor 
.
So, if ABC is scaled by 5 to for A'B'C', the area of A'B'C' will be 
times the area of ABC.
The other exercise is basically identical.

Answer:
$2.50
Step-by-step explanation:
The equation that describes Elizabeth's table can be found using the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (47.50 -27.50)/(3 -1)(x -1) +27.50
y = (20.00)/2(x -1) +27.50
y = 10x +17.50
Elizabeth's flat fee is $17.50. The difference between that and Mang's flat fee is ...
|17.50 -20.00| = |-2.50| = 2.50
The absolute value of the difference between the flat fees is $2.50.
Set up an equation. Since the ratio is 3:4 male:female, it would be 3m=4f. Since you know that 3m=18, solve for m and plug it into the 3m=4f equation to get the number of females! Don't forget that the number of females is 4f not just f!
I don't understand the question but if I think what I think the question is asking me I would say 2 feet
