2*(x-5) = -33, so x-5 = -16.5, so x = -11.5

This is assuming that "the difference between a and b" is a-b, which seems to be the accepted interpretation.

Hallar la ecuación de la recta que pasa por los puntos A(1,3) y B(3,7). Representarla gráficamente. Indicar su pendiente.

Fynjy0 [20]

Answer:

Step-by-step explanation:

la recta:

$y-yo=m(x-xo)$ (*)

P=(xo,yo)

$m=\frac{Ya-Yb}{Xa-Xb}$

substituindo:

$m=\frac{3-7}{1-3}\\\\m=2$

Seja P=A=(xo=1,yo=3), utilizando a formula (*)

$y-3=2(x-1)\\y=2x-2+3\\y=2x+1$

What is 3d+8=2d-7 is equations

fredd [130]

3d + 8 = 2d - 7 equals d = -15.

First, subtract 2d from both sides. Your problem should look like: 3d + 8 - 2d = -7.
Second, simplify 3d + 8 - 2d to get d + 8. Your problem should look like: d + 8 = -7.
Third, subtract 8 from both sides. Your problem should look like: d = -7 - 8.
Fourth, simplify -7 - 8 to get -15. Your problem should look like: d = -15, which is your answer.

Hopefully this helps, I'm not exactly sure what you meant by "is equations," but this is how you solve the problem.
