f(x)= -99.4x + 198.8

f(1) = -99.4*1 + 198.8 = 99.4

f(2) = -99.4*2 + 198.8 = 0

f(3) = -99.4*3 + 198.8 = -99.4

f(4) = -99.4*4 + 198.8 = -198.8

There are premium tickets costing $99 each and rest are regualr tickets costing $25 each. A pile of 120 tickets have a total val
polet [3.4K]

Answer:

There are 38 premium tickets and 82 regular tickets in a pile.

Step-by-step explanation:

Given,

Total number of tickets = 120

Total amount = $5812

Solution,

Let the number of premium tickets be x.

And the number of regular tickets be y.

Total number of tickets is the sum of total number of premium tickets and  total number of regular tickets.

So the equation can be written as;

x+y=120\ \ \ \ \ equation\ 1

Again,total amount  is the sum of total number of premium tickets multiplied by cost of each premium ticket and  total number of regular tickets multiplied by cost of each regular ticket.

So the equation can be written as;

99x+25y=5812\ \ \ \ equation\ 2

Now We will multiply equation 1 by 25 we get;

x+y=120\\25(x+y)=120\times25\\25x+25y= 3000 \ \ \ \ equation\ 3

Now Subtracting equation 3 from equation 2 we get;

(99x+25y)-(25x+25y)=5812-3000\\\\99x+25y-25x-25y=2812\\\\74x=2812\\\\x=\frac{2812}{74}=38

We will now substitute the value of x in equation 1 we get;

x+y=120\\38+y=120\\y=120-38\\y=82

Hence There are 38 premium tickets and 82 regular tickets in a pile.

What are the relative minimum and relative maximum values over the interval [−4,4] for the function shown in the graph?
kobusy [5.1K]

Answer:

Relative minimum :  -36

Relative maximum :  64

The rate of change is 336 greater

Step-by-step explanation:

Relative minimum are the minimum values  in the interval

Looking at the graph, we find the lowest point in the interval

Relative minimum : (-3, -36) and (3,-36)  y value -36

Looking at the graph, we find the highest point in the interval

Relative maximum : (0,64)  y value 64

Average rate of change = f(x2) - f(x1)

                                          ---------------

                                            x2 - x1

                                       

                                         f(7) - f(5)     1469 - 549      920

                                        ------------- = ---------------   = ------- = 460

                                             7-5               7-5                2

                                         f(4) - f(2)     287 - 39         248

                                        ------------- = ---------------   = ------- = 124

                                             4-2               4-2                2

We need to subtract

460-124

336

PLEASE HELP ASAP!! ILL GIVE BRAINLIEST IF CORRECT
Natalka [10]

Answer:

Function 1 has a greater Y intercept than that of function 2

Step-by-step explanation:

Y intercept can be found by replacing x by 0 or

x = 0 0f the given function.

in this case Function 1 has a Y intercept of 5 when x =0

on the other hand, function 2 crosses the y axis once at -1 which is the y intercept.

you can now clearly see that

y = 5 > y = -1

---> 5>-1

so that's why we conclude that 1 has a greater Y intercept.
