Answer:

x = 2

Step-by-step explanation:

Given

3x + 1 = x + 5

Subtract x from both sides

3x - x + 1 = x - x + 5

2x + 1 = 5

Subtract 1 from both sides

2x + 1 - 1 = 5 - 1

2x = 4

Divide both sides by 2

x = 4/2

x = 2

Answer:

x=2

Step-by-step explanation:

3x+1=x+5

Subtract x from each side to get all the variables on one side

3x-x+1=x-x+5

2x+1 = 5

Subtract 1 from each side to get all the constants on the other side

2x+1-1 = 5-1

2x= 4

Divide each side by 2

2x/2 =4/2

x =2

Given P(1,3) and Q(3,7) what is the slope of PQ
Aleksandr [31]

Answer:

hi! you have 2 points! this means slope formula! y2-y1/x2-x1

okay all you do now is plugin! (x1 1,y1 3) (x2 3,y2 7) what I did was label your x1 y1 x2 y2! now just follow the formula and that / is division or basically a fraction

7-3/3-1

that equals -5! and that's your slope! memorize the formula it helpss!

Porfabor necesito ayuda en la esta pregunta. ¿Encuentra cuatro pares ordenados de la siguiente función? f(x) = X3 – 2X2 – 2
zlopas [31]

Answer:

(0, -2), (1, -3), (2, -2) y (3, 7) son pares ordenados de f(x) = x^{3}-2\cdot x^{2}-2.

Step-by-step explanation:

Un par ordenado es un elemento de la forma (x,f(x)), donde x es un elemento del dominio de la función, mientras f(x) es la imagen de la función evaluada en x. Entonces, un par ordenado que está contenido en la citada función debe satisfacer la siguiente condición:

La imagen de la función existe para un elemento dado del dominio. Esto es:

x \rightarrow f(x)

Dado que f(x) es una función polinómica, existe una imagen para todo elemento x. Ahora, se eligen elementos arbitrarios del dominio para determinar sus imágenes respectivas:

x = 0

f(0) = 0^{3}-2\cdot (0)^{2}-2

f(0) = -2

(0, -2) es un par ordenado de f(x) = x^{3}-2\cdot x^{2}-2.

x = 1

f(1) = 1^{3}-2\cdot (1)^{2}-2

f(1) = -3

(1, -3) es un par ordenado de f(x) = x^{3}-2\cdot x^{2}-2.

x = 2

f(2) = 2^{3}-2\cdot (2)^{2}-2

f(2) = -2

(2, -2) es un par ordenado de f(x) = x^{3}-2\cdot x^{2}-2.

x = 3

f(3) = 3^{3}-2\cdot (3)^{2}-2

f(3) = 7

(3, 7) es un par ordenado de f(x) = x^{3}-2\cdot x^{2}-2.

(0, -2), (1, -3), (2, -2) y (3, 7) son pares ordenados de f(x) = x^{3}-2\cdot x^{2}-2.

How can help me pls I need help
dolphi86 [110]

Answer:

\lim_{x \to 2^-} x^3=2^3=\boxed8\\  \lim_{x \to 2^+} 3x-4=3\cdot 2-4=6-4=\boxed2

\lim_{x \to 2} f(x) does not exist

Step-by-step explanation:

Inserting 2 to both formulas, you get different results. In that cases, a limit does not exist
