Answer:

Explicación paso a paso:

Primero, puede crear ecuaciones como este:

Carmen = x + 4x + 2

Daniel = 4x

Tomas = 9x + 2

Marco = 2

42 = 9x + 2 + x + 4x + 2 + 4x + x

38 = 19x

x = 2

La edad de Marco = 2, entonces:

Daniel = 4 (2) = 8

La edad de Daniel = 8

T = 9 (2) +2

Carmen = 5 (2) +2

La edad de Carmen = 12

entonces La edad de Tomás es = 20

Answer:

La edad de Tomas= 20.

Step-by-step explanation:

Primero, puede crear ecuaciónes como este:

C= x+4x+2

D=4x

T= 9x+2

M=2

42= 9x+2+x+4x+2+4x+x

38= 19x

x= 2

La edad de Marco= 2, entonces:

D= 4(2)= 8

La edad de Daniel=8

T= 9(2)+2

La edad de Tomas= 20

C= 5(2)+2

La edad de Carmen= 12

2(x-3) = (x-1) + 7<br><br> Please show your steps!!
andre [41]
Simplify the equation.

First, distribute the 2 in the left side of the equation.
Resulting in: 2x-6 = (x-1) + 7

Second, remove the parentheses form the right side of the equation (there is nothing to distribute there).
Resulting in: x - 1 + 7

Now simplify the right side of the equation by subtracting the 1 from the 7.
Resulting in: x + 6

Our goal is to isolate the x to the left side, and the numerals to the right side.
With that in mind, add the 6 (from the right side) to both sides. This cancels out the 6 on the right side.
Resulting in: 2x = 12

Lastly, in order to fully isolate the variable (x), we divide both sides by 2.
Resulting in: x = 6

Hope this helps.

Choose the correct answer for each of the following questions Find the y-intercept for following equation F(X)=-(X+1)^21- -12- -
devlian [24]

Solution

Find the y-intercept for following equation:

f(x)=-(x+1)^2

Using the slope equation formular:

\begin{gathered} y=mx+c \\ f(x)=-(x+1)^2 \\ f(x)=-x^2-2x-1 \end{gathered}

The value of y when x = 0

\begin{gathered} f(0)=-0^2-2(0)-1 \\ y=-1 \end{gathered}

Hence the answer is - 1
