Answer:

I think this is what your asking

Step-by-step explanation:

Isometries are sometimes also called congruence transformations. Two figures that can be transformed into each other by an isometry are said to be congruent (Coxeter and Greitzer 1967, p. ... If a plane isometry has more than one fixed point, it must be either the identity transformation or a reflection.

8. For questions 8-9, determine whether the two figures are similar. If so, give the scale factor of the smaller figure to the l
Vinvika [58]

Question 8:

Your choice is correct: two figures are similar if all correspondant sides are in the same ratio.

In your case, the figure on the right have correspondant sides which are all three times the figure on the left, since

12 = 4\times 3, 21 = 7\times 3, 54 = 18\times 3

So, the two figures are similar and their ratio is 1:3.

Question 9:

We follow exactly the same approach: let's see if the radii and the heights are in the same ratio: the radii are in ratio

\cfrac{3.2}{2} = 1.6 = \cfrac{16}{10} = \cfrac{8}{5}

While the heights are in ratio

\cfrac{6.4}{4} = 1.6 = \cfrac{16}{10} = \cfrac{8}{5}

So, the answer is again yes, they are similar, and the ratio is 1.6.

-3x+2y=6 Find the intercepts. Show your work.
Arte-miy333 [17]

Answer:

The x-intercept is (-2,0)

The y-intercept is (0,3)

Step-by-step explanation:

An x-intercept is the point when the graph crosses the x-axis. In other words, the y-coordinate of the x-intercept is 0 (since it lays on the x-axis). In other words, to solve for the x-intercept(s), plug in 0 for y and solve for x:

-3x+2y=6\\-3x+2(0)=6\\-3x=6\\x=-2

So, the x-intercept is (-2,0).

Likewise, the y-intercept is the point when the graph crosses the y-axis. Because it's on the y-axis, the x-coordinate value would be 0. Thus, to find the y-intercept, plug in 0 for x and solve for y:

-3x+2y=6\\-3(0)+2y=6\\2y=6\\y=3

Thus, the y-intercept is (0,3).
