Mathematics

4 0

Answer:

30

Step-by-step explanation:

Triangle containing 120° and y° is an isosceles triangle.

Therefore,

y° + 120° + y° = 180°

2y° = 180° - 120°

2y° = 60°

y° = 60°/2

y ° = 30°

y = 30

Which equation shows y+15=3x in standard form?<br> PLZ help, I'm desperate 12 pts!!!
stepladder [879]
You have to put it in y=mx+b form so you subtract 15 to both sides so put it under the 3x and then it would be y=3x-15. Hope it's correct.

The chocolate Shoppe has a rectangular logo for their business that measures 2 1/2 feet tall with an area that is exactly the ma
Ilya [14]

The equation that could be used to determine L, the unknown side length of the logo is A =2.5w

<h3>How to determine the equation?</h3>

The given parameters in the question are:

  • Shape: Rectangle
  • Height of logo, h = 2 1/2 feet

From the question we understand that the area is at maximum.

Represent this area with A

The area of the rectangle is:

A = h * l

Where h and l are the dimensions of the rectangle.

Substitute 2 1/2 for h

A = 2 1/2 * l

Express 2 1/2 as a decimal number

A = 2.5 * l

Evaluate the product

A =2.5l

Hence, the equation that could be used to determine L, the unknown side length of the logo is A =2.5w

Substitution<br> 1.y=-5x-19<br> y=-6x-24<br><br> 2.y=-6x-22<br> y=-3x-10
omeli [17]

Answer:

1. y=5 and x=-5

2. y=2 and x=-4

Step-by-step explanation:

1.y=-5x-19

y=-6x-24

since both equations are equal to y, they are also equal to eachother

-5x-19=-6x-24

addition P.O.E.

x-19=-24

addition P.O.E.

x=-5

substitute x into one equation

y=-5*-5-19

y=6

2. y=-6x-22

y=-3x-10

since both equations are equal to y, they are also equal to eachother

-6x-22=-3x-10

addition P.O.E.

-22=3x-10

addition P.O.E.

-12=3x

division P.O.E.

-4=x

substitute x into one equation

y=-3*-4-10

y=2
