Mumz [18]

Answer:

y = 3

Step-by-step explanation:

We need to find the slope. We do so by choosing any two points and dividing the change in the y-coordinates (their difference) by the change in the x-coordinates (their difference). Let's just choose (1, 3) and (0, 3). The slope is: . So, the slope is 0.

We want to write a line in slope-intercept form, which is: y = mx + b, where m is the slope and b is the y-intercept (where the line crosses the y-axis). Here, the slope m = 0. Looking at the graph, we see that the y-intercept is (0, 3), so b = 3. Then, our line is: y = 0x + 3 ⇒ y = 3.

Another note is that this is a horizontal line. One thing to remember is that all horizontal lines have slopes of 0, so their function is simply y = k, where k is a constant through which the line cuts through.

Resuelve las siguientes ecuaciones y luego verifica A-)3x +1=7 B-)2a-2=1+3a

jarptica [38.1K]

Answer:

A) x=2

B) a=-3

Step-by-step explanation:

La primera ecuación dada es,

A) 3x + 1 = 7

Reste 1 de ambos lados, tenemos

3x +1-1=7-1

$\Rightarrow 3x=6$

Dividir por 3 (ya que 3 es un número distinto de cero) de ambos lados, tenemos

$\frac{3x}{3}=\frac {6}{3}$

$\Rightarrow x=2$

Ahora, compruebe si x = 2 es la solución correcta o no.

El lado izquierdo de la ecuación dada es 3x + 1.

Ponga x = 2, tenemos

$3\times2+1=7$

Que es igual al lado derecho de la ecuación dada.

Por tanto, x = 2 es la solución correcta.

La segunda ecuación es

B) 2a-2=1+3a

Reste 3a de ambos lados, tenemos

2a-2-3a=1+3a-3a

$\Rightarrow -a-2=1$

Suma 2 de ambos lados, tenemos

-a-2+2=1+2

$\Rightarrow -a=3$

Multiplica por -1 (como -1 es un número distinto de cero) de ambos lados, tenemos

$-a\times (-1)=3\times(-1)$

$\Rightarrow a=-3$

Ahora, verifique si a = -3 es la solución correcta o no

El lado izquierdo de la ecuación dada es 2a-2.

Ponga a = -3, tenemos

$2\times(-3)-2=-8$

El lado derecho de la ecuación dada es 1 + 3a.

Ponga a = -3, tenemos

$1+3\times(-3)=-8$ .

Aquí, al poner a = -3, el valor del lado izquierdo es igual al valor del lado derecho.

Por tanto, a = -3 es la solución correcta.

Kelly, Laura, and Tia so boxes of cookies for a fundraiser. Kelly sold 15 boxes less than Laura. Tia so twice as many boxes as K

Andre45 [30]

Answer:

Laura 32

Kelly 17 )

Tia 34

Step-by-step explanation:

L+ (L-15) + 2(L-15) = 83

4L - 45 = 83

4 L = 128

L = 32

Laura 32

Kelly 17 (32-15)

Tia 34 (2*17)

32+17+34 = 83

Urgent! don't know why i'm stuck...

ioda

When you're given an ordered pair and a system of equations, always try plugging the point in and seeing if the result is true or false.

3x + 4y = 18
2x - 2y = 2

3(2) + 4(3) = 18
6 + 12 = 18
18 = 18 is true.

2(2) - 2(3) = 2
4 - 6 = 2
-2 = 2 is false.

this point is not a solution for this system of equations. it works for the first equation, but not for the second.
