I have a really bad grade in Geometry right now and I

Andrews [41]

Answer: A. (x - 4, y - 2)

B. (x + 7, y - 11)

<u>Step-by-step explanation:</u>

A) How do you get the x-coordinate of 3 to become a x-coordinate of -1? by subtracting 4 --> x - 4

How do you get the y-coordinate of 5 to become a y-coordinate of 3? by subtracting 2 --> y - 2

The transformation is: (x - 4, y - 2)

B) How do you get the x-coordinate of -4 to become an x-coordinate of 3? by adding 7 --> x + 7

How do you get the y-coordinate of 11 to become a y-coordinate of 0? by subtracting 11 --> y - 11

The transformation is: (x + 7, y - 11)

Get the mixed number into one fraction
$\frac{3}{2} + \frac{3}{5} + \frac{1}{8}$
Get a common denominator
$\frac{60}{40} + \frac{24}{40} + \frac{5}{40}$
Now add
$\frac{89}{40}$
You can get it back to a mixed number
$2 \frac{9}{40}$

A rational expression has been simplified below.

Margaret [11]

<span>The first thing to do here is simplify both sides. X=4/9 is simplified, but you can simplify the other side by canceling out the (x-2) in the numerator and denominator.

</span><span>The expression should be (x + 4)(x - 2)/9(x - 2)= (x + 4)/9. After simplification by (x - 2) , the remainder is (x + 4)/9. When x = -4, both sides equal to zero When x = 0 , both sides equal to 4/9

I hope my answer has come to your help. God bless and have a nice day ahead!

Find an explicit rule for the nth term of a geometric sequence where the second and fifth terms are -6 and 162, respectively.

Vesna [10]

Answer:

b. an = 2 • (-3)^(n - 1)

Step-by-step explanation:

Before we test a solution or two, we can easily discard most of them.

We see the values alternate of signs (-5 for the 2nd term and +162 for the 5th term)... so the progression factor has to be negative (in order to alternate sign). <u>That already excludes answers A and C.</u>

Normally, a geometric progression has the (n-1) exponent, not (n+1), so our chances seem to be better with B.

We can test both D and B with n = 2, to obtain -6

Let's test answer D before:

$a_{2} = 2 * (-3)^{2+1} = 2 * (-3)^{3} = 2 * -27 = -54$

The result is -54, not -6... so it's not the right result.

Let's test answer B then:

$a_{2} = 2 * (-3)^{2-1} = 2 * (-3)^{1} = 2 * -3 = -6$

Right! Let's verify with n=5 to get 162:

$a_{5} = 2 * (-3)^{5-1} = 2 * (-3)^{4} = 2 * 81 = 162$

Confirmed, answer is B. an = 2 • (-3)^(n - 1)

Hello,

I suppose C is at the same altitude as A
else we can't anwser.
C=(4;1)

Slope of AB= (3-1)(4-1)=2/3

The equation of CD is
