Lera25 [3.4K]

Nine days. You can divide 108 by 36, to get how many times she has to read 36 pages, which is 3. Then you multiply that by 3, because she uses 3days for every 36 pages. 3x3=9

Find the circumcenter of the triangle (-2,4) (-2,-1) (1,-1)

lana66690 [7]

Answer:

( $-\frac{1}{2}$ , $\frac{3}{2}$ )

Step-by-step explanation:

( $x_{1}$ , $y_{1}$ )

( $x_{2}$ , $y_{2}$ )

Coordinates of midpoint are

( $\frac{x_{1} +x_{2} }{2}$ , $\frac{y_{1} +y_{2} }{2}$ )

~~~~~~~~~~~~~~~~~~~~

The figure is right triangle.

The circumcenter is the middle of the hypotenuse.

( - 2, 4 )

( 1 , - 1 )

( $-\frac{1}{2}$ , $\frac{3}{2}$ )

Timmy writes the equation f(x) = x – 1. He then doubles both of the terms on the right side to create the equation g(x) = x – 2.

skelet666 [1.2K]

The graph lines stay the same, however the y-intercept changes from (-1,0) to (-2,0), since it is now g(x) = x - 2, instead of f(x) = x - 1.
