hello, John says the transformation rule (x, y) Right-arrow (x + 4, y + 7) can be used to describe the slide of the pre-image (4

, 5) to the image (0, –2). What was his error?

Answer:John's error is that he applied the transformation rule to the image instead to the pre-image.The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5). This results to (4, 5) + (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image.

What is the solution to this system of linear equations2x+3y=3 and 7x-3y24
Kay [80]

For this case we have a system of two equations with two unknowns:

2x + 3y = 3\\7x-3y = 24

We follow the steps below:

We add the equations:

9x = 27

We divide between 9 on both sides of the equation:

x = \frac {27} {9}\\x = 3

We substitute the value of "x" in the first equation and find the value of y:

2 (3) + 3y = 3\\6 + 3y = 3\\3y = 3-6\\3y = -3\\y = \frac {-3} {3}\\y = -1

Thus, the solution of the system is: (3, -1)

Answer:

(3, -1)

Find the generating function for the sequence 1,-2,4,-8, 16, ...
kirill [66]

Answer:

  a(x)=\dfrac{1}{1+2x}

Step-by-step explanation:

The generating function a(x) produces a power series ...

  a(x)=a_0+a_1x+a_2x^2+a_3x^3+\dots

where the coefficients are the elements of the given sequence.

We observe that the given sequence has the recurrence relation ...

  a_0=1;a_n=-2a_{n-1} \quad\text{for n $>$ 0}

This can be rearranged to ...

  a_n+2a_{n-1}=0

We can formulate this in terms of a(x) as follows, then solve for a(x).

\sum\limits^{\infty}_{n=1} {a_{n}x^n} =a(x)-a_0 \quad\text{and}\\\\\sum\limits^{\infty}_{n=1} {2a_{n-1}x^n} =(2x)a(x) \quad\text{so}\\\\\sum\limits^{\infty}_{n=1} {(a_n+2a_{n-1})x^n}=0=a(x)-a_0+2xa(x)\\\\a(x)=\dfrac{a_0}{1+2x}=\dfrac{1}{1+2x}

The generating function is ...

  a(x) = 1/(1+2x)

Alex
I believe your answer is B.37 because if u make the x a 5 like shown in the equation it now looks like h(5)=8(5)-3 so now you solve it and i got 37 i hope this helps you!<span />

A temperature recorded in Antarctica was -121Fahrenheit. The temperature recorded in the Sahara desert was 132 fahrenheit. How m
rodikova [14]

Answer: 253°F

Step-by-step explanation:

Given the following :

Temperature in Antarctica = - 121 Fahrenheit

Temperature in Sahara desert = 132 Fahrenheit

Number of degrees in which Sahara desert is warmer than Antarctica :

(temperature in Sahara desert - temperature in Antarctica)

= ( 132°F - (-121°F))

= (132°F + 121°F)

= 253°F

Sahara Desert is 253°F warmer
