What is the image of the point (5,-4) after a rotation of 90° counterclockwise about the origin?​

Mathematics
1 answer:
Debora [2.8K]3 years ago
4 0

Answer:

(4,5)

Step-by-step explanation:

Rotating a <em>point </em>by 90 degrees <em>counterclockwise</em> would make the y become x and switch it's negative/positive value, and make x the y.

Ex: (x,y) would become (-y,x)

G(x) = −2x + 4<br> f (x) = −4x − 12/5 <br> Are they inverses or not
katen-ka-za [31]

Answer:

  • No, they are not inverses

Step-by-step explanation:

  • g(x) = −2x + 4
  • f (x) = −4x − 12/5

<u>Let's get inverse of g(x) and compare it with f(x):</u>

  • g(x)= -2x + 4
  • x = - 2g'(x) + 4
  • 2g'(x) = - x + 4
  • g'(x) = -1/2x + 2

g'(x) and f(x) are different so the answer is No

Solve for the zeros of the quadratic function f(x) = 9.2 + 6x +1. Write the answer as a fraction.
VladimirAG [237]

Answer:

x = -1.7, or x = -17/10

Step-by-step explanation:

f(x) = 9.2 + 6x + 1 is a linear function and as such (and because the slope is not zero) has only one solution.  Combining like terms, we get

f(x) = 10.2 + 6x = 0 (you must set this equal to zero if solving for zero(s).

Then 6x = -10.2, and x = -1.7, or x = -17/10

The sum of the quotient of a number and and 3 and 8 is 16 what is the number
zhuklara [117]
After having done this on paper:

\frac{n}{3} + 8 = 16

We want to isolate the variable, and the first step is to subtract the 8.

\frac{n}{3} = 8

Since the <em>n</em> is being multiplied by 3, and that = 8, we can multiply both sides by 3.

<em>n</em> = 24

Let me know if this helped you understand better.

Also, you can check this by substituting in 24 for <em>n</em>.
