Metropolitan high school sells sweat shirts and t shirts at each athletic event. during the first event, they sold 12 sweatshirts and 8 t-shirts for a total of $312. the school took in $300 during a second event by selling 8 sweatshirts and 13 t-shirts. what is the price of one sweatshirt and one t shirt HELP NOW PLEASEEEE

Answer 1
Answer:

Answer:

T = $12

S =$18

Step-by-step explanation:

This question would be solved using simultaneous equation

Let t = cost of t-shirt

s = price of sweatshirt

two equations can be derived from this question

12s + 8t = 312   eqn 1

8s + 13t = 300   eqn 2

Multiply eqn 1 by 8 and eqn 2 by 12 :

96s + 64t = 2496 eqn 3

96s + 156t = 3600 eqn 4

subtract eqn 3 from 4

92t =1104

t = 12

Substitute for t in eqn 1

12s + 8(12) = 312

12s + 96 = 312

12s = 216

s = 18

Each of the letters in the word APPLE is on separate cards, face down on the table. If you pick a card at random, what is the probability that its letter will be A or L?

Answers

Probability =

         (number of possible ways to succeed)
divided by
         (total number of possible outcomes) .

Number of ways to succeed = 2  (pick the 'A' or the 'L')

Total number of possible outcomes = 5 (the cards on the table) .

Probability of success  =  2/5  =  40% .

Write the equation for f(x)=x^2But flipped over the x-axis, shifted 4 units down, and shifted 1 unit to the left.

Answers

Answer:

f^\prime(x)=-(x+1)^2-4

Step-by-step explanation:

We have the function:

f(x)=x^2

And we want to write its equation after being: 1) Flipped over the x-axis, 2) shifted 4 units down, and 3) shifted 1 unit to the left.

To denote a flip over the x-axis, we multiply the function by -1. Hence:

f^\prime(x)=-x^2

Is our function flipped over the x-axis.

To shift n units vertically, we simply add n to our function.

Since we are going 4 units downwards, we will add -4 to our function. Hence:

f^\prime(x)=-x^2-4

Finally, to shift n units horizontally, we substitute our variable x for (x-n).

Since we are shifting 1 unit to the left, n=-1. Hence, we will substitute x for (x+1). Therefore:

f^\prime(x)=-(x+1)^2-4

So, our final function is:

f^\prime(x)=-(x+1)^2-4
