Find a range of th fucunction f(x)=4x-1 for the domain{-1,0,1,2,3}

1 answer:

7 0

F(x) = 4x - 1

All you have to do is substitute the values in the domain for x in the function.

f(-1) = 4(-1) - 1
f(-1) = -4 - 1
f(-1) = -5

f(0) = 4(0) - 1
f(0) = -1

f(1) = 4(1) - 1
f(1) = 4 - 1
f(1) = 3

And so on.

After 45 seconds, Camden’s bathtub fills with 3 inches of water. How many seconds will it take to fill Camden’s tub with 20 inch

Pepsi [2]

So you have to find how many seconds it takes to fill up with 1 inch.
TO find that, you have to divide 45/3 which equals to 15.
So it takes 15 seconds for 1 inch. The question is asking you to find out how many seconds will it take to fill the tub with 20 inches.
SO your gonna multiply 15*20.
15*20 = 300
So it would take 300 seconds to fill up Camden's tub.

Answer: B) (x-1)2+(y+1)2= 25 radius = 5 miles

Step-by-step explanation:

In order to get this answer you see that you are adding a negative to x in the first part then multiplying it by 2. Second, you add y+1 then multiplying it by 2. You get the radius of 25 which equals 5 miles. Look at the graph to also check your answers to the problem.

Iliada went to Minewaska state park one day this summer. All of the people at the park were either either hiking or bike riding.

B r = 178 + h;
b r + h = 676;
then, 178 + 2h = 676 => h = 498/2 = 249 => b r = 178 + 249 = 427;

How can 1/5x − 2 = 1/3x + 8 be set up as a system of equations? a . 5y − 5x = −10. 3y − 3x = 24 b. 5y − 5x = −10. 3y + 3x = 24 c

VMariaS [17]

The answer is d. 5y − x = −10. 3y − x = 24

$\frac{1}{5}x-2= \frac{1}{3}x+8=y$
⇒    $y= \frac{1}{5}x-2$
   $y= \frac{1}{3}x+8$
________________________
$y= \frac{x}{5} -2= \frac{x}{5} - \frac{10}{5} = \frac{x-10}{5}$
$y= \frac{x}{3} +8= \frac{x}{3} + \frac{24}{3} = \frac{x+24}{3}$
________________________
$y= \frac{x-10}{5}$ ⇒    $5y=x-10$
$y= \frac{x+24}{3}$   ⇒    $3y=x+24$
________________________
$5y-x=-10$
$3y-x=24$

Fifteen students are going hiking on their spring break. They plan to travel in three vehicles—one seating 7, one seating 5, and

andriy [413]

Answer:

The students can group themselves in 360360 ways

Step-by-step explanation:

For this exercise we need to use the following equation:

$\frac{n!}{n1!*n2!*...*nk!}$

This equation give us the number of assignation of n elements in k cell, where n1, n2, ..nk are the element that are in every cell

In this case we have 15 student that need to be assign in three vehicles with an specific capacity. This vehicles would be the equivalent to cells, so we can write the equation as:

$\frac{15!}{7!*5!*3!}$

Because the first vehicle have 7 seating, the second vehicle have 5 seating and the third vehicle have 3 seating.

Solving the equation we get 360360 ways to organized 15 students in three vehicles with capacity of 7, 5 and 3 seating.
