100 POINTS HELP ASAP Linear Combination

notka56 [123]

Answer:

1) $x=\dfrac12$

2) $n = -3 \ \ \textsf{and} \ \ m = -4$

3) see below

4) A: 0 = 1

Step-by-step explanation:

<u>Question 1</u>

$15-0.5(4x-2)+4x=17$

$\implies 15-2x+1+4x=17$

$\implies 2x+16=17$

$\implies 2x=1$

$\implies x=\dfrac12$

<u>Question 2</u>

$\textsf{rearrange} \ n=m+1 :$

$\implies -m=-n+1$

$\textsf{add equations} \ -m=-n+1 \ \textsf{and} \ m=2n+2:\\$

$\implies0=n+3$

$\implies n=-3$

$\textsf{substitute} \ \ n=-3 \ \ \textsf{into} \ \ m=n-1:$

$\implies m=-3-1$

$\implies m=-4$

<u>Question 3</u>

subtract the second equation from the first

divide both sides by -4

substitute found value for y into first equation

solve for x

<u>Question 4</u>

$3j=k$

$k=3j+1$

$\textsf{rearrange} \ 3j=k :$

$\implies -k=-3j$

$\textsf{add equations}\ -k=-3j \ \ \textsf{and}\ \ k=3j+1:$

$\implies 0=1$

Solution = A

Write an equation of the line in slope-intercept form.<br><br><br><br> The equation is y= <br> .

aivan3 [116]

Answer:

y = x + 2

Step-by-step explanation:

Slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. Here, b is equal to 2 because the line crosses the y-axis at 2. THe slope is rise over run, or the change in y divided by the change in x. From the two points given, we get 3/3 which is equal to 1. 1x equals x, so this gives us "no slope." Putting it together gives us y = x + 2.

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

Find the equation of the line which passes through the point

sammy [17]

Answer:

$y= \frac{1}{5}x- \frac{56}{5}$

Step-by-step explanation:

We want to find the equation of the line that goes through: !6,-10) and is perpendicular to the line

$5x + 3y = 2y - 3$

Let's simplify the equation of the line to get:

$3y - 2y = - 5x + 3$

$y = - 5x + 3$

The slope of this line is -5.

The perpendicular to this line has a slope of

$\frac{1}{5}$

The equation going through (6,-10) is

$y=m(x-x_1)+y_1$

We substitute to get;

$y= \frac{1}{5} (x-6) - 10$

Expand;

$y= \frac{1}{5}x- \frac{6}{5} - 10$

$y= \frac{1}{5}x- \frac{56}{5}$
