Answer:

$\boxed{\large\sf y = 3x - 5}$

Step-by-step explanation:

Here we are given a equation which is ,

$\longrightarrow y = 3x + 6$

We need to find out the equation of the line which is parallel to the given line and passes through the given point .

And as we know that the slope of two parallel lines are equal .

On comparing the given equation with slope intercept form (y = mx + c )of the line , we have ,

$\longrightarrow m = 3$

Therefore the slope of the parallel line will be ,

$\longrightarrow m_{||}= 3$

Now we can use the point slope form of the line which is ,

$\longrightarrow y - y_1 = m(x - x_1)$

Substitute ,

$\longrightarrow y - 7 = 3 ( x -4)\\\\\longrightarrow y -7 = 3x -12 \\\\\longrightarrow y = 3x -12+7\\\\\longrightarrow y = 3x -5$

This is the required answer .

Exercise 2.1.47 Prove that ifA^-1 exists and AX=0 then X =0.

stepan [7]

Answer:

Step-by-step explanation:

If $A^{-1}$ exist, then we have that $A^{-1}\cdot A=1$ .

Therefore, in the case that $AX=0$ , if we multiply both

terms in the equation by $A^{-1}$ , then we have

$A \cdot A^{-1}X=A^{-1}0$

and so the equation tells us that

$X=A\cdot A^{-1}X=A^{-1}0=0$ .

Answer:

x=90

Step-by-step explanation:

So, since x-20 is the vertical angle directly near 70, we can say:

x-20=70.

if we solve x is 90.
