What is the image point of (0,1) after the transformation D4 R90?<br> Please and thank you
Ede4ka [16]

Answer:

Image point → (-4, 0)

Step-by-step explanation:

Coordinate of a point → (0, 1)

Rule for the transformation has been given as,

D₄ o R₉₀

First use R₉₀ → Rotation of the point by 90° counterclockwise

Rule for the rotation of a point (x, y) by 90° counterclockwise about the origin,

(x, y) → (-y, x)

(0, 1) → (-1, 0)

Further use D₄ → Dilation of the point by a scale factor of 4 about the origin

If a point (x, y) is dilated by a scale factor 'k' about the origin rule for the dilation is,

(x, y) → (kx, ky)

By applying this rule,

(-1, 0) → (-4, 0)

Therefore, image point will be → (-4, 0)

Solve the system of equations
Elden [556K]

Answer:

Step-by-step explanation:

-4x + 2y = -30

-2x + 2y = -10

-4x + 2y = -30

 2x - 2y = 10

-2x = -20

x = 10

-2(10) + 2y = -10

-20 + 2y = -10

2y = 10

y = 5

(10, 5)

The price of a new car is 16000$ Mr Mar paid 15% of the price as a down payment how much does he still owe? (Please help and exp
Harlamova29_29 [7]
Ok 15% is 0.15 in decimal form so you multiply 0.15 by 16000$ and get 2,400$ (the down payment not amount owed) you then subtract 2,400$ from 16,000$ and get 13,600$ which is how much he still owes
