Answer:

f =  -  \frac{5}{3}  \\

Step-by-step explanation:

\frac{ - 3f}{4}  =  \frac{5}{4} \\ cross \:  \: multipication  \\  - 12f = 20 \\  \frac{ - 12f}{ - 12}  =  \frac{20}{ - 12}  \\ f =  \frac{20}{ - 12}  \\ f =  -  \frac{5}{3}

hope this helps

brainliest appreciated

good luck! have a nice day!

Answer:

f=-\frac{5}{3}

Step-by-step explanation:

-\frac{3}{4}f=\frac{5}{4}

(4)-\frac{3}{4}f=(4)\frac{5}{4}

-3f=5

\frac{-3f}{-3}=\frac{5}{-3}

f=-\frac{5}{3}

PLEASE PLEASE PLEASEE PLEASEEEEESE HELPME!?!?!? IM SO BAD AT MATH PLEASE HELP!!!
Fiesta28 [93]
For this case we have the following function:
 f (x) = 0.01 * (2) ^ x

 By definition, the average rate of change is given by:
 AVR =  \frac{f(x2) - f(x1)}{x2 - x1}
 We evaluate the function for the given values:
 For x = 7:
 f (7) = 0.01 * (2) ^ 7

f (7) = 1.28
 For x = 14:
 f (14) = 0.01 * (2) ^ {14}  f (14) = 163.84
 Then, replacing values we have:
 AVR = \frac{163.84 - 1.28}{14 - 7}
 AVR = 23.22
 Answer:
 
the average rate of change from x = 7 to x = 14 is:

Find an equation of the line that passes through the points (-0.5,0.75) and (0.75,-0.5)
Keith_Richards [23]

The equation of the line can be shown using the slope intercept form that is

y= mx+b

where m is the slope and b is the y intercept

So firstly we have to find the value of slope m

To find the value of slope m we apply the formula

m= \frac{( y_{2} - y_{1})}{( x_{2} - x_{1})}

So we can plug the values using the two given points

(-0.5,0.75) and (0.75,-0.5)

m= \frac{(-0.5-0.75) }{(0.75-(-0.5))} = \frac{-1.25}{1.25} = -1

So m = -1

Plug m=-1 in the equation we get

y= -1x +b

Now we have to find the value of b

to find the value of b , we plug any one pint in the equation

0.75 = -1(-0.5) +b

0.75 = 0.5 +b

Subtract 0.5 from both sides

0.25 = b

or

b= 0.25

Now plug the value of b , in the equation

we get

y = -1x +0.25

hence the equation of the line is y = -1x +0.25

Factor the trinomial x^2 - 7x + 10
Valentin [98]

Answer:

(x-5) (x-2)

Step-by-step explanation:

x^2 (-2x-5x) +10

basically you will write the equation down and then to double check multiply the x and then the -5 into (x-2). this can be repetitive if you get it wrong so try to do numbers that make sense.
