Answer:
(x,y) → (ax,ay) .
Step-by-step explanation:
A dilation is a transformation that changes the size of the image. It either shrink or enlarge a shape by using a scale factor about a center of dilation.
If we transform point (x,y) by using dilation with scale factor k (assume center of dilation at (0,0) then the coordinate of the image will be (kx,ky).
So, the coordinate expression represents the coordinates of any point after dilation by a scale factor of a:
(x,y) → (ax,ay) .
Answer:
[tex]\huge\boxed{(ax, ay)}[/tex]
Step-by-step explanation:
In order to dilate the coordinates of a point, we want to make it [tex]a[/tex] times bigger. In order to do this, we can multiply the x and y values by our scale factor, a. This is called mapping. What it does is it basically multiplied our points by a specific number so that we end up with a figure that is [tex]a[/tex] (the scale factor) times bigger than the original.
So in order to make an expression for this, we multiply the x and y coordinates by a. So we have ax and ay.
Hope this helped!
Solve for h. -18+7h>12+9h
Answer:
[tex]h<-15[/tex]
Step-by-step explanation:
[tex]-18+7h>12+9h[/tex]
Add 18 to both sides:
[tex]-18+7h+18>12+9h+18[/tex]
[tex]7h>9h+30[/tex]
Subtract 9h from both sides:
[tex]7h>9h+30[/tex]
[tex]-2h>30[/tex]
Multiply both sides by -1 and flip the symbol:
[tex]\left(-2h\right)\left(-1\right)<30\left(-1\right)[/tex]
[tex]2h<-30[/tex]
Divide both sides by 2:
[tex]\frac{2h}{2}<\frac{-30}{2}[/tex]
[tex]h<-15[/tex]

find the initial value seventeen years from now, Ms. speedis car, which is depreciating at 20% per year, will be worth $500
Answer:
Around 22200 dollars
Step-by-step explanation:
Firstly, it was depreciating 20% per year for 17 years. So, if we were to go back in time, it would be appreciating by 25%. Therefore, after doing the plugging in, it is 500 * 1.25^17. The initial value is around 22200. It is around 22204, to be exact.

(3,-7) and (4,0) distance formula
Answer: approximately 7.07
Step-by-step explanation:
The distance formula is [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]. Since we are given teo points, we can plug them in and solve.
[tex]d=\sqrt{(4-3)^2+(0-(-7))^2}[/tex] [parenthesis]
[tex]d=\sqrt{(1)^2+(7)^2}[/tex] [exponent]
[tex]d=\sqrt{1+49}[/tex] [add]
[tex]d=\sqrt{50}[/tex] [square root]
[tex]d=7.07[/tex]
The distance is approximately 7.07.
What is £36 in the ratio 2:1:1
Answer:
