I need help! I will give brainliest, if correct!
nekit [7.7K]

<em>kx</em> + <em>z</em> = 3 means <em>z</em> = 3 - <em>kx</em>. Substitute this into the first two equations:

<em>x</em> + <em>y</em> + 3 (3 - <em>kx</em>) = 10   ==>   (1 - 3<em>k</em>) <em>x</em> + <em>y</em> = 1

-4<em>x</em> + 3<em>y</em> + 5 (3 - <em>kx</em>) = 7   ==>   (-4 - 5<em>k</em>) <em>x</em> + 3<em>y</em> = -8

Multiply through the first equation by -3 :

-3 ((1 - 3<em>k</em>) <em>x</em> + <em>y</em>) = -3 (1)   ==>   (-3 + 9<em>k</em>) <em>x</em> - 3<em>y</em> = -3

Add this to the second equation to eliminate <em>y</em> :

((-3 + 9<em>k</em>) <em>x</em> - 3<em>y</em>) + ((-4 - 5<em>k</em>) <em>x</em> + 3<em>y</em>) = -3 + (-8)

(-7 + 4<em>k</em>) <em>x</em> = -11

Normally, you would solve for <em>x</em> by dividing both sides by -7 + 4<em>k</em>. But you can't do that if this turns out to be equal to 0, which happens for

-7 + 4<em>k</em> = 0   ==>   <em>k</em> = 7/4

2x-2=x+45 <br> Can someone figure out the value of x?
Andre45 [30]

Answer:

<h3>x=47</h3>

Step-by-step explanation:

To solve this problem, first, you have to isolate x on one side of the equation. Isolate it on one side of the equation.

2x-2=x+45

2x-2+2=x+45+2 (First, add 2 from both sides.)

45+2 (Solve.)

45+2=47

2x=x+47

2x-x=x+47-x (Then, subtract x from both sides.)

47-x (Solve.)

47-x=47

x=47

In conclusion, the final answer is x=47.

Simplify each expression, if possible.<br> 13. (2+ 5xi)(7- xi)
vaieri [72.5K]

Answer:

Step-by-step explanation:

(2+5xi)(7-xi)=2(7-xi)+5xi(7-xi)

=14-2xi+35xi-5x²i²

=14+33xi-5x²(-1)

=14+33xi+5x²

=14+5x²+33xi

Given two points m and n on the coordinate plane, find the slope of line mn, and state the slope of the line perpendicular to li
ololo11 [35]
The slope of the line MN where M (9,6) and N (1,4) can be obtained by obtaining the rate of the rise over the run. This is shown below:

(y2 - y1)/(x2 - x1) = (4 - 6)/(1 - 9) = (-2)/(-8)
m1 = 1/4

The slope of the line perpendicular to line MN can be obtained by taking the negative reciprocal of the slope of line MN.

m1 = 1/4
m2 = -1/m1 = -1/(1/4) = -4

Therefore, the slope of the line perpendicular to line MN is -4.
