Which of the following equations defines a line that is parallel to the line y=-4/3x-4 and passes through the point (3,-1)

ValentinkaMS [17]

Answer:

Step-by-step explanation:

given that your slop is -4/3, plug the (x,y) point in to the equation of y = -4x/3 +b

-1 = -4 + b , b = 3

y = -4x/3 + 3

For the graphed function f(x) = (4)x − 1 + 2, calculate the average rate of change from x = 1 to x = 2.

lorasvet [3.4K]

Average rate of the function: 3

Step-by-step explanation:

The function in this problem is

$f(x)=4^{x-1}+2$

The average rate of change of a function over an interval $(x_1,x_2)$ is given by

$r=\frac{f(x_2)-f(x_1)}{x_2-x_1}$

where

$f(x_1),f(x_2)$ are the values of the function calculated in $x_1,x_2$ respectively

For the function in this problem we have:

$x_1=1$ , so

$f(x_1)=f(1)=4^{1-1}+2=4^0+2=1+2=3$

$x_2=2$ , so

$f(x_2)=f(2)=4^{2-1}+2=4^1+2=4+2=6$

So, the average rate of change is

$r=\frac{6-3}{2-1}=\frac{3}{1}=3$

james tailoring service charges a flat rate of $20 and charges an additional $12 per hour when making a tailored suit. how much

jeka94

Answer:

It will cost Mr. Smith $68 to make his suit.

Step-by-step explanation:

Since the charge $12 per hour, and it takes 4 hours to make the suit, then we need to multiply 12 by 4.

12 × 4 = 48

Now we need to add the flat rate since that is the initial charge for service.

48 + 20 = 68

This means it will cost Mr. Smith a total of $68 for his suit.
