The lines whose equations are 2x + y = 3z and x + y = 6z intersect at which point?

1 answer:

3 0

2x + y - (x + y) = 3z - 6z
--------------------------------------------------------
x = -3z 
------------------------------------------

(-3z, 9z) 
----------------------------------
(x,y,z) = (-3z, 9z, z)
--------------------------
x = -3z, y = 9z
---------------------
There for the answer is (-3z, 9z)

What Is -0.75-(-2/50)+0.4(-3/4)? Explain and answer the question please

lilavasa [31]

The answer is -1.01
I first changed the signs of the ones i could. So -0.75+(2/50)+0.4(-3/4)
Then i multiplied the 0.4*-3/4 which equals -0.3
So you are left with -0.75+(2/50)-0.3
2/50 is equal to 0.04 so now it is -0.75+0.04-0.3 and the rest is simple math. Which equals -1.01

SashulF [63]

The Solution.

The given equation is

$\begin{gathered} y=|x|+7 \\ \text{Where x=11} \end{gathered}$

Substituting 11 for x, we can get the value of y.

$\begin{gathered} y=|11|+7 \\ y=11+7 \\ y=18 \end{gathered}$

Hence, the value of y is 18.
