<h3>Answer: Yes it is a function</h3>

Each point listed is of the form (x,y). The x coordinate is always listed first. We dont have any repeat x values, so this is enough to conclude we have a function.

If you wanted to, you could graph each point given on the same coordinate grid. Note how none of the points stack on top of each other. Or put another way, note how it is impossible to draw a single straight line through more than one point graphed. This graph passes the vertical line test.

A function is where plugging in any x value leads to exactly one y value.

If you had two points like (5,2) and (5,7) then the input x = 5 leads to more than one output y = 2 and y = 7 at the same time, making this example not a function.

Solve for x, ab and bc
Savatey [412]

Answer:

x = 5

AB = 26

BC = 39

Step-by-step explanation:

A___B___C

AC = AB + BC

65 = (5x+1) + ( 7x+4 )

65 = 12x + 5

12x = 65-5

12x = 60

x = 60/12

x = 5

AB = 5x +1 = 5(5) +1 = 25 +1 = 26

BC = 7x+4=7(5) + 4 = 35 +4 = 39

I hope I helped you^_^

Using synthetic division, find (x4 − 2) ÷ (x + 1).
Fiesta28 [93]

Answer:

Step-by-step explanation:

We have given:

x^4-2/x+1

Put x+1 = 0

x= 0-1

x= -1

-1 | 1   0   0   0   -2

  |      -1   1   -1     1

_______________

    1    -1   1  -1    -1

Thus it makes the expression:

x^3-x^2+x-1 - 1/x+1

You can further confirm this expression by solving the expression:

(x4 − 2) ÷ (x + 1).

x^4 - 1 -1/x+1

x^4-1/x+1 - 1/x+1

(x^2-1) (x^2+1)/x+1 - 1/x+1

(x-1)(x+1) (x^2+1)/x+1  - 1/x+1

x+1 n the numerator will be cancelled out by x+1 in the denominator.

(x-1) (x^2+1) - 1/x+1

Multiply (x^2+1) by x-1

x(x^2+1) -1(x^2+1)  - 1/x+1

x^3+x-x^2-1 - 1/x+1

x^3-x^2+x-1 - 1/x+1 ....

n200080 [17]

Answer:

$158.75

Step-by-step explanation:

Given:

The Maple Car Rental Comany charges a flat fee of $45 plus 35 cents per mile

And we have to write a linear equation that gives the total cost in terms of numbers of miles driven then find the total cost if the renter drives 325 miles.

Solution:

Total cost = 35 cents of renter drives in miles + fixed charge of the car

Total cost = 0.35\times325 +45

                = 113.75  + 45\\= 158.75

Thus,  total cost is $158.75, when the renter drives 325 miles.
