How do you find the inverse of y=2x-3

Mathematics

Lady bird [3.3K]3 years ago

Subtract 3 from each side

y - 3 = 2x

 

Divide through by 2

y/2 - 3/2 = x

or x = y/2 - 3/2

 

Now simply switch labels: x↔y

y = x/2 - 3/2

Answer:

In order to subtract a whole number from a fraction, you first have to turn the hole number into a mixed fraction.

y = 3/2x + b

Plug in the point (2,2) and solve for b.

2 = (3/2)(2) + b

2 = 3 + b

b = -1

Final equation is y = 3/2x - 1.

1.Encuentra de dos formas diferentes el área de las figuras mostradas en cada literal:​
MA_775_DIABLO [31]

Answer:

Cuadrilátero A: A = y^{2}+4\cdot y +4

Cuadrilátero B: A = a^{2}+6\cdot a + 9

Step-by-step explanation:

Existen dos formas distintas de determinar las áreas de cada cuadrilátero:

(i) <em>Obtener el área de cada cuadrado y sumar los resultados.</em>

(ii) <em>Calcular los lados del cuadrilátero grande y determinar el área. </em>

Cuadrilátero A

Método (i)

A = y^{2}+2\cdot y +4+2\cdot y

A = y^{2}+4\cdot y +4

Método (ii)

A = (y+2)\cdot (y+2)

A = y^{2}+4\cdot y + 4

Cuadrilátero B

Método (i)

A = a^{2}+3\cdot a +9 + 3\cdot a

A = a^{2}+6\cdot a +9

Método (ii)

A = (a+3)\cdot (a+3)

A = a^{2}+6\cdot a + 9
