Y = 3x - 1

The format for slope intercept form is:

y = mx + b

m represents the slope and that was given so:

y = 3x + b

Now we have to substitute the value from the given point into “y” and “x” to solve for “b”

(2) = 3(1) + b
2 = 3 + b
-1 = b

Now that we know b we can substitute it into y = 3x + b to get the equation of the line

y = 3x - 1

Macy's if offering a sale where you can use two different coupons, Coupon A gives 15%
Juliette [100K]

The ticket price of the item after applying coupon B first and then coupon A is $65.45

Coupons reduce the ticket price of an item.

<u><em>Ticket price</em></u><u><em> after </em></u><u><em>coupon B i</em></u><u><em>s applied </em></u>

An item costs $80. After applying the coupon B which gives, $3 off the price, the cost of the item reduces to $77 ($80 - $3).

The ticket price of the item after coupon B is applied is $77

<em><u>Ticket price </u></em><em><u>after c</u></em><em><u>oupon A </u></em><em><u>is applied </u></em>

The item costs $77 when coupon B is applied. If the discount is 15% off on coupon A, it means that the item costs 85%( 100 - 15%) of its initial price.

Ticket Price of the item = percentage price x price of the item after the first coupon B was applied

85% x $77

0.85 x $77 = $65.45

Answer:

x+2

Step-by-step explanation:

x^3+6x^2+11x+6/x^2+4x+3

= x^3+6x^2+11x+6/x^2+4x+3

= (x+1)(x+2)(x+3)/(x+1)(x+3)

=x+2

PLEASE HELP DUE IN 40 MINS!! Using the Law of Sines, find the exact answer for x.
Savatey [412]

Answer:

Step-by-step explanation:

Sin(30) / X  = Sin(45) / 12

use algebra to isolate X

1 / X = [ Sin(45) / 12  ]   /  Sin(30)

flip both sides

X =  Sin(30) / [Sin(45) /12 ]

invert the denominator on the right side

X = Sin(30) *  12/ Sin(45)

Do you know what Sin(30) is off the top of your head?

and also Sin(45) ?

these are worth remembering... and you can b/c they are just

sin(0) = 0/2

sin(30) = 1 / 2

sin(45) = \sqrt{2}/2

sin(60)= \sqrt{3} / 2

sin(90) = \sqrt{4} / 2    (aka 1)

note the numerators just counts up  0, 1, 2, 3, 4  :)  

Cos works the same way but counts from 90° back to 0 but exactly like sin other wise, hence why Cos and Sin both = \sqrt{2}/2 at 45 °

anyway

X =  1 / 2 * 12/ \sqrt{2}/2

X = 3\sqrt{2}

A=3

B= 2

:)  nice , huh
