8 + 2r = −10 what is r?

Answers

Answer:

r = -9

Step-by-step explanation:

Subtract 8 from both sides to get 2r = -18. Divide by 2 on both sides to get r = -9.

Answer:

r=-9

Step-by-step explanation:

Step 1:- Simplify both sides of the equation.

2r+8 = -10

Step 2:- For isolating the variable, subtract 8 from both sides.

2r+8-8 = -10-8

2r = -18

Step 3:- For isolating the variable, divide by 2 from both sides.

2r/2 =-18/2

r= -9

(12x - 1.7) - (17x + 6.7) =

Answers

Answer: -5x-8.4

Step-by-step explanation:

$\left(12x-1.7\right)-\left(17x+6.7\right)$

remove the parentheses

$12x-1.7-17x-6.7$

Simplify

Group like terms

$12x-17x-1.7-6.7$

Add

$12x-17x=-5x=$

$-5x-1.7-6.7$

Subtract

$-1.7-6.7=-8.4$

= $-5x-8.4$

Answer:

-5x-8.14 is the correct answer

Step-by-step explanation:

First distribute the terms

12x - 1.7 - 17x -6.7 =

Then add/subtract similar terms

12x - 17x = -5x

-1.7 -6.7 = -8.14

so it's -5x -8.14

Step-by-step explanation:

This is a combination of 7 objects taken 5 at a time

nCr = n! / r! * (n - r)!

7C5 = 7! / (5! (7-5)!)

= 7! /(5! 2!)

= (7*6*5*4*3*2*1)

-----------------------

5*4*3*2*1 * 2*1

Canceling

= 7*6/ (2*1)

4/3v =12

Simplify your answer as much as possible.

Answers

$\frac { 4 }{ 3 } v=12\n \n \frac { 3 }{ 4 } \cdot \frac { 4 }{ 3 } v=\frac { 3 }{ 4 } \cdot 12\n \n v=\frac { 36 }{ 4 } \n \n v=9$

4/3v = 12
3/4 × 4/3v = 12 × 3/4
v = 9

How is the graph of log (x – 5) translated from the graph of log x?

Answers

Answer:

The graph of y=logx shifts 5 units right to get the graph of y=log(x – 5).

Step-by-step explanation:

The parent log function is

$y=\log x$

The translation of the function is defined as

$y=\log (x+a)+b$ .... (1)

Where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

The given function is

$y=\log (x-5)$ .... (2)

From (1) and (2), we get

$a=-5,b=0$

Since a=-5<0, therefore the graph of y=logx shifts 5 units right to get the graph of y=log(x – 5).

The transformation of g(x) to f(x) is g(x) is shifted left by 5 unit to f(x).

Describing the transformation of f(x) to g(x).

From the question, we have the following parameters that can be used in our computation:

The functions f(x) and g(x)

Where, we have

f(x) = log(x - 5)

g(x) = log(x)

So, we have

Difference = 5 - 0

Evaluate

Difference = 5

This means that the transformation of g(x) to f(x) is g(x) is shifted left by 5 unit to f(x).
