Answer: Ix - 950°C I ≤ 250°.

Step-by-step explanation:

Ok, the limits are:

700°C to 1200°C.

The first step is to find the mean these numbers:

M = (700°C + 1200°C)/2 = 950°C

Now let's find the distance between the mean and the limits (which is equal to half the difference between our numbers)

D = (1200°C - 700°C)/2 = 250°C.

Now we can write our relation as:

Ix - MI ≤ D

Ix - 950°C I ≤ 250°.

if x = 1200°C.

I1200°C - 950°CI = 250°C ≤ 250°C ---- true.

if x = 700°C

I700°C - 950°CI = I-250°CI = 250°C ≤ 250°C ---- true

Four friends all use $10 off coupons to buy themselves concert tickets.
eimsori [14]

Answer:

$64

Step-by-step explanation:

Since there were 4 of them and the coupons were $10 off, they saved a total of $40

To find how much they would have spent without the coupons, add 40 to 216:

216 + 40

= 256

To find the normal cost of one ticket, divide this by 4:

256/4

= 64

So, the price of one concert ticket without the coupon is $64

PLEASE HELP THANK YOU
Svetllana [295]

Answer:

change in the total cost for each book printed = $15

cost to get started (before books are bought) = $1200

Step-by-step explanation:

IF the eqn is y = 15x +1200

where y  represent the total cost of publishing a book (in dollars) and

x  represent the number of copies of the book printed


then cost to get started (before books are bought) can be found by substitute x=0 into the eqn

y = 1200 + 15*0 = $1200


change in the total cost for each book printed will be the difference in total cost at x=0 and x=1

when x=0, y=1200

when x=1, y=1200+15*1=1215

so the change in total cost=$15
