Circle B has a radius of 7.2in. Find the diameter of circle B dilated by a factor of 8.1

Since the scale factor is greater than 1, this dilation will be an enlargement. Therefore, you multiply 7.2 times 8.1 to get 58.32. This question asks for diameter, so multiply 58.32 times 2 to get 116.64 in.

The graph of the even function F(X) Has 5 x-intercepts if (6,0) is the one of the intercepts what set of points can be the other
alex41 [277]

f(x) being even means


f(x) = f(-x)


So the zeros come in positive and negative pairs. If there are an odd number of intercepts like there are here, it's because one of them is x=0 which is its own negation.


Given zero x=6 we know x=-6 is also a zero.


So we know three zeros, and know the other two zeros are a positive and negative pair.


The only choice with (-6,0) and (0,0) is A.


Choice A

100 divided by 9 and 3/5100 divided by 9 3/5
Tems11 [23]
100/9 is equal to 11.11.
3/5100 is equal to 0.00058824
And 9 3/5 is equal to 5.4( here you multiply 9 by 3 and after you divided the result with 5)

Solve the following equation-7x-4y=-4 -9x-5y=-6
maks197457 [2]

Answer:

\boxed{x = 4~~and~~ y = -6}

.

Step-by-step explanation:

-7x - 4y = -4 (times 5) -35x - 20y = -20

-9x - 5y = -6 (times 4) -36x - 20y = -24

.

Eliminate both equations

-35x - 20y = -20

<u>-36x - 20y = -24 </u>  <u>  </u>

x = 4

.

Substitute the value of x to one of equations

-7x - 4y = -4

-7(4) - 4y = -4

-28 - 4y = -4

-4y = - 4 + 28

-4y = 24

y = \frac{24}{-4}

y = -6
