What is the coefficient b makes the equation true for any real number x -3 (2x-3) + 5x = bx + 9

QveST [7]

Answer:

b = 0

Step-by-step explanation:

x -3 (2x-3) + 5x = bx + 9

x - 6x +9 + 5x = bx + 9

-9 -9

x - 6x + 5x = bx

-5x + 5x = bx

0 = bx

b/x 0/x

b = 0

Someone told me the answer was 39?? Is this true? Why ? please help.

The problem has the equation:

f(x) = (3) ^ (x/2)

In order to get the average increase in the number of flowers being pollinated from day 4 to day 10, then we need to use the equation substituting x with 4 to 10

f(4) = 9
f(5) = 12.59
f(6) = 27
f(7) = 46.77
f(8) = 81
f(9) = 140.30
f(10) = 243

Then add all the values and divide it by 7
= 559.66 / 7
= 79.95

So the correct answer is 79.95

How would you graph f(x) = 7x + 5 when you reflect it over y axis and translate it 3 units left

SOVA2 [1]

Answer:

See explanation

Step-by-step explanation:

Given the function $f(x)=7x+5$

1. To reflect the graph of the function f(x) over the y-axis, you should change the slope of the line in opposite. The slope of the function f(x) is 7, so the slope of the reflected function will be -7 and the expression of the reflected function will be

$g(x)=-7x+5$
