Jan bought a new sweater. It was priced at $32.00 and there was a 25% discount. She
gave the cashier $40.00. What was her change?

Answer:

y=x-9

y=2x-15

Step-by-step explanation:

To solve this we can just pick a random number for our slope and solve for the y intercept

For example lets say the slope is 1

we know that wehn x=6 y= -3 so we have the following equation

-3= 6+b

B is -9

which means one equation is

y=x-9

We can just repeat this same process

Let's say the slope is 2

-3 = 2*6+b

-3= 12

b= -15

which means taht

y=2x-15

Answer:

all are correct

Step-by-step explanation:

Answer: x = 5, y = 2; Solution = (5, 2)

Step-by-step explanation:

Substitution

2x + y = 12

x + 2y = 9

x + 2y = 9

Subtract 2y from both sides

x = 9 - 2y

Now, substitute x for (9 - 2y) in the first equation

2x + y = 12

2 (9 - 2y) + y = 12

Distribute 2

18 - 4y + y = 12

18 - 3y = 12

Subtract 18 from both sides

-3y = -6

Divide both sides by -3

y = 2

Now to find x, substitute 2 for y in (x = 9 - 2y)

x = 9 - 2y

x = 9 - 2(2)

x = 9 - 4

x = 5

Solution: (5, 2)

Elimination

2x + y = 12

x + 2y = 9

Multiply the second equation by -2 to find y

2x + y = 12

(x + 2y = 9) -2

2x + y = 12

-2x - 4y = -18

Add both equations

2x and -2x are cancelled out

You get:

-3y = -6

Divide both sides by -3

y = 2

Substitute 2 for y in any of the equations to find x

I chose x + 2y = 9

x + 2y = 9

x + 2 (2) = 9

x + 4 = 9

Subtract both sides by 4

x = 5

Solution = (5, 2)

Btw you can use any of these methods, I used both so you could know that you get the same answer no matter the method.

Hope I helped!

Answer:

16 ft

Step-by-step explanation:

We start by converting 1yd to ft,

1yd = 3ft

So in the smaller triangle, we have 3ft, 4.5ft. Using Sine, Cos, and Tan rule. We know that

TanΦ = opposite / adjacent

TanΦ = 3ft / 4.5ft

TanΦ = 0.667

Φ = Tan^-1 0.6

Φ = 33.69

This means that the angle of elevation is 33.69°

Using this angle, and the same tan rule again, we gave

Tan 33.69 = opp/24

0.667 = opp/24

opp = 24 * 0.667

opp = 16 ft

The function would be y = 0.45x, x being the number of seconds, y being the items he can ring up.

For example (this is an example only to show how this equation works), if we were looking at how many items the cashier can ring in 5 seconds, we would make the equation y = 0.45(5), and with multiplication, we can find that they would ring 2.25 items ( y = 2.25 )

Answer:

0.6b - 3c

Step-by-step explanation:

Multiply 0.2 and 3b

0.2 x 3b = 0.6b

Then multiply 0.2 and 15c

0.2 x 15c = 3c

We can't add these, 3c and 6b because they have different letters.

different letter vs. different letter =

don't add

different letter vs. normal number like 5 =

dont add

same letter vs. same letter =

add

normal number vs. normal number =

add

This all goes the same for dividing, subtracting, and multiplying

Answer:

Equation- s + 456 = 437 (I'm not completely sure if this is what your wanting but it is possible to solve the problem with this equation. if this isn't what you need I can write another)

Step-by-step explanation:

s represents the starting height.

s + 456 = 437

first subtract 456 from either side, 437 - 456 = -19.

s = -19 (I'm not sure if this is correct it's been a few months since I've used variables for equations but I tried)
